Tha MCHC àrd is ann ainneamh agus gu tric nas feumail mar chomharra na mar dhearbhadh. Is e a’ cheist phractaigeach am bheil na ceallan dearga gu fìrinneach dùmhail agus cruinn, no an do rinn an sampall ceàrr air an àireamhachadh.
- Raon MCHC mar as trice 32-36 g/dL (320-360 g/L) ann an inbhich, ged a tha raon an leabhair-lann fhèin a’ gabhail prìomhachas.
- MCHC àrd os cionn 36 g/dL tha e neo-àbhaisteach agus bu chòir dha sgrùdadh a bhrosnachadh airson spherocytes, hemolysis, losgadh, no bacadh anailis.
- Spherocytes tha iad nam ceallan dearga beaga, dùmhail às aonais gealachadh meadhanach agus faodaidh iad tachairt ann an hereditary spherocytosis no autoimmune hemolytic anemia.
- Agglutinins fuara faodaidh iad MCHC àrdachadh gu mearachd le bhith a’ cruinneachadh cheallan dearga, a’ lughdachadh cunntas RBC tomhaiste, agus a’ cur bacadh air clàr-amais àireamhach.
- Lipemia faodaidh hemoglobin a bhith air a mheas ro mhòr air cuid de luchd-anailis, a’ cruthachadh MCHC àrdaichte eadhon nuair a tha cumadh nan ceallan dearga àbhaisteach.
- Leòn-loisgidh is urrainn do leòn-loisgidh MCHC àrd fhìor a dhèanamh tro chall ball-frèam dearg-chill, mar as trice còmhla ri anemia agus fianais obair-lann de hemolysis.
- Sanasan hemolysis a’ toirt a-steach reticulocytes àrdaichte, bilirubin neo-dhìreach agus LDH, le haptoglobin ìosal nuair a tha ceallan dearga a’ briseadh sìos sa bhodhaig.
- Ath-dheuchainn le sampall EDTA a chaidh a chruinneachadh o chionn ghoirid, air a làimhseachadh gu ceart gu tric is e a’ chiad cheum ciallach nuair a tha MCHC air leth agus dìreach beagan àrd.
MCHC àrd air CBC: an fhreagairt dhìreach
Mar as trice tha MCHC àrd a’ ciallachadh gu bheil ceallan dearga gu math dùmhail, ach is urrainn dha cuideachd ciallachadh gun deach an inneal-sgrùdaidh a mhealladh leis an t-sampall. Ann an inbhich, tha MCHC os cionn timcheall air 36 g/dL airidh air co-theacsa: mar as trice tha àrdachaidhean fìor a’ comharrachadh a dh ionnsaigh spherocytes no leòn teirmeach cudromach, fhad ‘s a tha fuar-ghreimean, lipemia, agus hemolysis sampall nan mìneachaidhean obair-lann cumanta. Bho 23 Lùnastal, 2026, cha bhithinn a’ lorg eas-òrdugh fala bhon chlàr-amais seo a-mhàin.
Tha MCHC air a thomhas mar hemoglobin air a roinn le hematocrit, air iomadachadh le 100, mar sin is e dùmhlachd a th’ ann seach tomhas cealla dìreach. Bidh hemoglobin de 15.0 g/dL agus hematocrit de 40% a’ toirt a-mach MCHC de 37.5 g/dL; faodaidh an àireamh èirigh leis gu bheil hemoglobin air a leughadh nas àirde, tha hematocrit air a leughadh nas ìsle, no an dà chuid. Tha an treòraiche bith-chomharraidhean CBC againn feumail nuair a tha grunn chlàran-amais air an comharrachadh aig an aon àm.
Nuair a nì mi ath-sgrùdadh air pannal le MCHC 36.5-37.5 g/dL ach hemoglobin, bilirubin, reticulocytes, agus RDW àbhaisteach, tha artifact mar as trice nas dualtaiche na tinneas. Tha MCHC de 39-42 g/dL gu math duilich gu fiosaigeach a chumail suas ann an ceallan dearga a tha a’ cuairteachadh gun mhilleadh, mar sin bu chòir don obair-lann casg a chuir air casg mus bi duine a’ gabhail clisgeadh.
Tha Kantesti na Anailisiche deuchainn fala AI a leughas MCHC còmhla ri hemoglobin, hematocrit, MCV, RDW, bilirubin, LDH, agus toraidhean roimhe an àite a bhith a’ làimhseachadh aon bhratach dhearg mar diagnosas. Tha riaghailt clionaigeach an Dotair Thomas Klein sìmplidh: dearbhaich an àireamhachd agus an sampall mus òrdaich thu obair-rannsachaidh leudachaidh; tha an rud againn gu mionaideach RDW agus stiùireadh clàr-amais nan ceallan dearga a’ mìneachadh carson a tha an dòigh seo stèidhichte air pàtrain cudromach.
Chan eil MCHC na MCH no MCV
Tha MCHC a’ toirt cunntas air dùmhlachd hemoglobin taobh a-staigh meud na cealla dearg phacaichte, fhad ‘s a tha MCH a’ toirt cunntas air meud hemoglobin gach cealla agus tha MCV a’ toirt cunntas air meud a’ chill. Tha bhith a’ cur troimh-a-chèile na trì clàr-amais seo mar aon adhbhar gum faod brataich cunbhalach CBC a bhith nas eagallach na tha iad.
Mar as trice tha MCH 27-33 pg gach ceall, fhad ‘s a tha MCV mar as trice 80-100 fL ann an inbhich; chan eil raon sam bith a’ mìneachadh MCHC. Faodaidh ceallan dearga mòra barrachd hemoglobin a ghiùlan agus mar sin àrdachadh MCH, ge-tà faodaidh an MCHC aca a bhith àbhaisteach oir tha an tomhas-lìonaidh aca air fàs gu co-chuimseach. Faic ar coimeas practaigeach de MCV agus MCH ma tha an dà luach air am brataich.
Gu tric bidh fìor àrd MCHC an cois MCV àbhaisteach no ìosal-àbhaisteach oir tha spherocytes air uachdar an t-seallaidh a chall agus air fàs nas cruinne, chan ann air sgàth ‘s gu bheil hemoglobin gun chrìoch annta. Tha an geoimeatraidh sin cudromach: tha nas lugha de dh’ uachdar aig cruinne airson an tomhas-lìonaidh aice, agus mar sin chan eil ionad bàn oirre air sleamhnan sampall cealla air a dheagh ullachadh.
Is e an rud, faodaidh àrdachadh ann an deuchainn fala MCHC a bhith fìor gu matamataigeach fhad ‘s a tha e a’ cur dragh air bith-eòlasach. Nì hematocrit a tha air a thoirt fo-mheas beag às dèidh cruinneachadh cheallan dearga an co-mheas a lìonadh suas eadhon ged nach eil ceallan dearga an euslaintich ro dhlùth idir; seo carson a tha ath-sgrùdadh cunntais fala iomlan bu chòir roimhe seo co-dhùnaidhean.
Spherocytes: an comharra clasaigeach fìor MCHC àrd
Is e spherocytes an adhbhar as aithnichte airson fìor àrd MCHC oir tha call an t-seallaidh a’ dèanamh cheallan dearga teann agus gu math trom le hemoglobin. Chìtear iad ann an spherocytosis oighreachail agus anemia hemolytic fèin-ghluasadach, ach feumar fianais smear a mhìneachadh le comharran agus comharran hemolysis.
Gu tric bidh spherocytosis oighreachail a’ toirt luachan MCHC os cionn 36 g/dL, reticulocytosis, a’ bhuidheach eadar-amail, clachan-mòra, splanomegaly, no eachdraidh teaghlaich de anemia. Tha an stiùireadh 2011 aig a’ Chomann Breatannach airson Haematology ag ràdh gu bheil MCHC a’ toirt taic don diagnosis ach nach eil e gu leòr mothachail no sònraichte airson a dhearbhadh leis fhèin (Bolton-Maggs et al., 2012).
Ann an anemia hemolytic fèin-ghluasadach, bidh antibodies a’ comharrachadh cheallan dearga airson toirt air falbh pàirt den t-sealladh anns an t-sruth, a’ fàgail spherocytes air an cùlaibh. Tha deuchainn antiglobulin dìreach, cunntas reticulocyte, bilirubin, LDH, agus haptoglobin nas fhiosraiche còmhla na clàr-amais sam bith air leth; an stiùireadh againn gu haptoglobin ìosal a bharrachd air hemolysis a’ còmhdach crìoch a tha furasta a chall.
Tha aon bhreabadh clionaigeach: faodaidh ath-mhuinntireachd o chionn ghoirid sgàil a dhèanamh no am pàtran spherocyte dachaigheil aig euslainteach a chòmhdach airson grunn sheachdainean. Tha Christensen et al. a’ toirt cunntas air ceangal eosin-5-maleimide le sruth-cytometry mar dheuchainn fheumail airson spherocytosis oighreachail a tha fo amharas, ged a bu chòir do neach-hematologist deuchainn a thaghadh agus a chlàr-ama gu faiceallach (Christensen et al., 2015).
Ciamar a bhios fios a bheil MCHC àrd a’ tighinn le hemolysis
Tha àrd MCHC a’ fàs nas ciallach gu clionaigeach nuair a bhios e an cois anemia, cunntas reticulocyte àrdaichte, àrdachadh bilirubin neo-dhìreach, àrdachadh LDH, agus haptoglobin ìosal. Tha an cruinneachadh sin a’ nochdadh àrdachadh ann an tionndadh cheallan dearga, ged nach eil aon chlàr-amais foirfe.
Faodaidh ceudad reticulocyte os cionn 2% a bhith neo-iomchaidh ann an anemia mhòr, mar sin gu tric bidh luchd-clionaigeach a’ tomhas cunntas absolute reticulocyte no clàr-amais toraidh reticulocyte nan àite. Mar eisimpleir, faodaidh cunntas reticulocyte 4% le hematocrit 24% nochdadh dìreach freagairt meadhanach cnàimh às deidh ceartachadh; an artaigil againn air comharran reticulocyte àrdaichte a’ dol troimhe.
Bidhidh am bilirubin neo-cheangailte suas nuair a thèid an t-seiche a phròiseas nas luaithe na as urrainn don ae a cheangal ris, fhad ‘s a dh’ èiricheas an LDH leis gu bheil an LDH pailt ann an ceallan dearga. Tha haptoglobin fo ìre as ìsle na obair-lann a’ toirt taic do hemolysis a-staigh, ach faodaidh e nochdadh àbhaisteach rè sèid leis gu bheil haptoglobin na phròtain geir. Bidh Barcellini agus Fattizzo a’ deasbad an ribe breithneachaidh seo san ath-sgrùdadh aca air anemia hemolytic autoimmune (Barcellini & Fattizzo, 2015).
Bidh fual dorcha, sgìths a tha a’ sìor fhàs, giorrad analach aig fois, pian broilleach, faochadh, no sùilean buidhe le fiabhras a’ moladh measadh clionaigeach air an aon latha. Tha ceallan briste mar stiùireadh smeur eadar-dhealaichte agus nas èiginn na sferocytes; ar mìneachadh air nuair a dh’ fheumas schistocytes ath-sgrùdadh èiginneach a’ cuideachadh le bhith a’ soilleireachadh carson.
Carson a dh’fhaodadh losgadh adhbhrachadh gu fìrinneach MCHC àrdaichte
Faodaidh milleadh teas mòr adhbhrachadh fìor àrd MCHC leis gu bheil teas a’ dèanamh cron air membran nan ceallan dearga, a’ toirt air falbh membran, ceallan coltach ri sferocyte, agus hemolysis. Tha seo mar as trice na fhaighinn san ospadal às dèidh losgadh a tha follaiseach gu clionaigeach, chan e mìneachadh airson toradh CBC neo-chinnteach taobh a-muigh an euslaintich.
Faodaidh milleadh teas microspherocytes a chruthachadh taobh a-staigh uairean a thìde bho losgadh mòr, agus faodaidh an MCHC èirigh mar a thuiteas an co-mheas membran ri meud. Faodaidh hemoglobin cuideachd tuiteam thar na làithean às dèidh sin bho ghluasadan lionn, modhan-obrach, phlebotomy, agus hemolysis a tha a’ dol air adhart, mar sin chan urrainn do aon MCHC cruinneas cruinneas milleadh a thomhas.
Tha mi air euslaintich fhaicinn uaireannan a’ cur fòcas air MCHC de 37.1 g/dL às deidh faighinn a-steach do shàr-èiginn fhad ‘s a tha iad a’ dearmad air mòran thar-ghnìomhachdan nas gnìomhaiche: hemoglobin a’ tuiteam, creatinine ag èirigh, atharrachaidhean potasium, no lactate. Anns an t-suidheachadh sin, bidh luchd-clionaigeach a’ riaghladh an neach agus fiosaig losgaidh, chan e an clàr-amais; ar clàr-ama deuchainn às dèidh ospadal a’ mìneachadh carson a dh’ fhaodas luachan gluasad gu luath.
Kantesti AI ’s e àrd-ùrlar mìneachaidh biomarcadairean AI a dh’ fhaodas clàr-amais MCHC àrd a chomharrachadh còmhla ri hemoglobin agus toraidhean dubhaig fiùghantach, ach feumaidh losgadh geur measadh ospadail dìreach agus chan urrainnear an riaghladh gu sàbhailte bho mhìneachadh aithisg. Bu chòir toradh às deidh losgadh mòr a bhith air a choimeas ris na 24-72 uairean roimhe sin, chan ann an aghaidh cuibheas coitcheann den t-sluagh.
Cold agglutinins: an artifact MCHC àrd a bhios dotairean a’ coimhead às a leth
Faodaidh fuasglaidhean fuar MCHC meallta àrd adhbhrachadh le bhith a’ dèanamh air ceallan dearga cruinneachadh aig teòthachd an t-seòmair mus tèid an anailis. Dh’ fhaodadh gun cunnt an anailisiche grunn cheallan ceangailte mar aon phàirt, a’ leantainn gu àireamh RBC gu bràth ìosal, MCV gu bràth àrd, agus MCHC tomhaiste inflated.
Is e am pàtran fuasgladh fuar clasaigeach àireamh RBC ìosal le MCV neo-chothromach àrd, MCH, agus MCHC àrd, gu tric gun sgeulachd clionaigeach a’ maidseadh. Tha teasachadh an tiùb EDTA gu 37°C agus ath-ruith an CBC gu tric a’ ceartachadh na luachan, a tha fada nas fhiosrachail na bhith ag ath-aithris deuchainn air thuaiream seachdainean às deidh sin.
Faodaidh fuasglaidhean fuar tachairt gu sealach às deidh cuid de ghalaran analach no maireannach ann an tinneas fuasglaidh fuar agus cuid de thinneasan lymphoproliferative. Bidh comharran mar atharrachadh dath no mì-chofhurtachd ann an corragan le nochd fuar a’ cur cuideam clionaigeach ris, ach is dòcha gur e am pàtran obair-lann fhèin a’ chiad stiùireadh; ath-dheuchainn às deidh hemolysis a’ tabhann ceistean tarraing a-rithist practaigeach.
Na bi gad theasachadh gu làidir no feuchaidh ri toraidhean a làimhseachadh aig an taigh. Faighnich an chunnaic an obair-lann cruinneachadh nan ceallan dearga, an deach an sampall a theasachadh agus ath-ruith, agus an deach hematocrit làimhe a dhèanamh; bidh na trì freagairtean sin gu tric a’ socrachadh na cùise.
Faodaidh lipemia agus hemolysis sampall atharrachadh MCHC
Faodaidh lipemia agus hemolysis sampall in-vitro MCHC a thogail gu meallta leis gu bheil mòran anailisichean a’ tomhas hemoglobin gu photometraigeach às deidh na ceallan dearga a bhith air am briseadh. Faodaidh lipidean neòlach no hemoglobin an-asgaidh san sampall an gabhail a-steach optach àrdachadh agus toirt air hemoglobin nochdadh nas àirde na tha e dha-rìribh.
Tha lipemia mar as trice ri fhaicinn às deidh cus triglycerides, mar as trice os cionn timcheall air 400-500 mg / dL, ged a tha eadar-theachd an urra ris an ionnstramaid agus tonn-tonn an sgrùdaidh. Faodaidh obair-lann blank plasma a chleachdadh, tonn-tonn eile, no dòigh eile an àite plasma seach dìreach a bhith a ’gabhail ris an toradh hemoglobin fèin-ghluasadach.
Bidh sèididh in-vitro a ’tachairt às deidh cruinneachadh no làimhseachadh, chan ann taobh a-staigh a’ chuirp, agus faodaidh e buaidh a thoirt air barrachd air MCHC. Faodaidh potasium, LDH, AST, agus phosphate èirigh ann an sampall millte, is e sin as coireach gu bheil MCHC àrd singilte còmhla ri potasium àrd ris nach robh dùil a ’feumachdainn sgrùdadh càileachd sampall; faic an stiùireadh againn gu mhearachdan potaisium co-cheangailte ri sèididh.
Tha sreath plasma a tha follaiseach pinc no dearg na chomharra obair-lann, chan e dearbhadh anemia sèididh san euslainteach. Is e an ath-ghnìomh practaigeach cruinneachadh ùr le làimhseachadh socair agus giollachd sgiobalta, gu sònraich nuair a tha clàr tùsail a ’toirt a-steach clàr-innse sèididh no beachd gum faodadh toraidhean a bhith air am faicinn.
Cruinneachadh, stòradh, agus trioblaidean tiùb a dh’atharraicheas clàr-amais CBC
Faodaidh droch mheasgachadh sampall, fo-líonadh, dòrtadh, agus casg air mion-sgrùdadh clàr-innse CBC atharrachadh, ged a bhios stòradh dàil mar as trice a ’lughdachadh seach a bhith a’ togail MCHC le bhith a ’leigeil le ceallan a bhith a’ sèid. Bu chòir MCHC àrd mar sin a leughadh le beachdan sampall an obair-lann, chan ann dìreach an àireamh air portal an euslainteach.
Mar as trice bidh sampallan CBC air an cruinneachadh ann an tiùban EDTA, agus faodaidh tiùb fo-líonaichte a bhith ann co-mheas anticoagulant-gu-sampall cus a dh ’atharraicheas tomhasan cealla. Faodaidh dòrtadh beag ceallan a thoirt air falbh gu roghnach bho sgrùdadh agus dèanamh cinnteach gu bheil an cunntas fèin-ghluasadach neo-chòrdail; ar n-sealladh air stuthan tiùb fala a ’mìneachadh carson nach eil seòrsa tiùb na fhìnealas.
Bidh stòradh aig teòthachd an t-seòmair airson ùine mhòr ag adhbhrachadh gum bi ceallan dearga a ’gabhail uisge, a’ togail MCV agus a ’crìonadh MCHC. Tha an stiùireadh sin de dh ’atharrachadh feumail: chan eil MCHC àrd gu math às deidh sampall dàil air a mhìneachadh gu fèin-ghluasadach le aois a-mhàin, mar sin faodaidh fuachd-chruinneachadh no eadar-theachd optigeach a bhith ann fhathast.
Faodaidh sampall capillary a bhith freagarrach ann an cuid de shuidheachaidhean ach tha e nas dualtaich atharrachadh cruinneachaidh na sampall EDTA venous air a chruinneachadh gu math. Ma tha MCHC àrd gun chomharran maidse no mì-ghnàthachaidhean co-cheangailte, is fheàrr leam mar as trice aon ath-tharraing venous glan mus tèid a làimhseachadh mar thinneas cròcronach ùr.
Cleachd CBCan roimhe gus co-dhùnadh a bheil an t-atharrachadh fìor
Tha àrdachadh obann ann am MCHC bho bhun-loidhne seasmhach 33-35 g / dL gu 38 g / dL nas coltaiche le duilgheadas sampall no lorgaire na an fhuil-mhuir-mhuir hereditary a tha a ’leasachadh gu slaodach. Chan eil gluasadan a ’dol an àite smear, ach tha iad nan comharra cumhachdach air smachd càileachd.
Tha raon MCHC pearsanta reusanta aig a ’mhòr-chuid de dhaoine thar ùine, gu tric ag atharrachadh le nas lugha na 1 g / dL nuair a tha suidheachaidhean deuchainn co-ionann. Tha sgrùdadh delta obair-lann a ’toirt coimeas eadar toradh ùr agus toradh roimhe gus atharrachaidhean neo-chòrdail a chomharrachadh mus tèid toraidhean fhoillseachadh; ar n-artaigil air sgrùdaidhean delta a ’sealltainn mar a tha an lìon sàbhailteachd sin ag obair.
Tha Kantesti na seirbheis eadar-mhìneachaidh deuchainn-lann AI a tha a ’toirt coimeas eadar luachan CBC gnàthach agus roimhe, a’ cuideachadh le bhith a ’comharrachadh comharra leantainneach bho aon-mach. Anns an t-sruth-obrach ath-bhreithneachaidh againn, tha atharrachadh MCHC nas cudromaiche nuair a bhios e a ’siubhal còmhla ri hemoglobin, MCV, bilirubin, agus reticulocytes ann an stiùireadh a tha beòthail.
Tha eisgeulan ann. Faodaidh sèididh fèin-dhìonach ùr, prìomh losgadh, freagairt dòrtadh fala, no cruinneachadh fuar mòr atharrachadh thoraidhean gu luath, mar sin tha luach eachdraidheil seasmhach a ’gealltainn ach chan e adhbhar a-riamh a bhith a’ dearmad jaundice ùr, fual dorcha, no anemia.
Suidheachaidhean a tha gu tric air am marbhadh air MCHC ach tearc an urra ris
Mar as trice chan eil dìth uisge, dìth iarainn, dìth bhiotamain B12, agus cuideam àbhaisteach ag adhbhrachadh MCHC àrd dha-rìribh. Faodaidh iad luachan CBC eile atharrachadh, ach cha bu chòir an cleachdadh mar mhìneachaidhean goireasach airson MCHC de 38 g / dL às aonais dearbhadh an sampall.
Mar as trice bidh dìth iarainn a’ lughdachadh MCH agus MCHC agus gu tric a’ lughdachadh MCV aon uair ‘s gu bheil dìth ann. Is dòcha gu bheil MCV àbhaisteach aig dìth iarainn tràth, ach chan eil e a’ mìneachadh clàr-amhairc hyperchromic; ar mìneachadh air TSAT ìosal a’ cuideachadh le bhith a’ sgaradh ruigsinneachd iarainn bho dùmhlachd CBC.
Bidh dìth Bhiotamin B12 no folate mar as trice ag adhbhrachadh macrocytosis, le MCV os cionn 100 fL, seach MCHC àrd. Ma tha MCV agus MCH àrd le chèile ach tha MCHC àbhaisteach, is e sin stiùireadh breithneachaidh eadar-dhealaichte; faic clàran-amhairc MCV àrd.
Bidh dìth G6PD ag adhbhrachadh haemolysis bho àm gu àm às deidh brosnachaidhean oxidative sònraichte ann an daoine a tha buailteach, ach chan e deuchainn sgrìonaidh earbsach a th’ ann an MCHC air a shon. Rè prìomh dheuchainn, faodaidh an smear agus na comharran tionndaidh a bhith nas fhollaisiche, agus is dòcha gum feumar deuchainn enzyme ath-aithris às deidh faighinn seachad air oir tha dùmhlachd G6PD nas àirde aig ceallan dearga òga.
Na deuchainnean leanmhainn as feumail às deidh MCHC àrdaichte
Is e an ceum as fheàrr a leanas airson MCHC àrd iomallach mar as trice ath-aithris CBC le sgrùdadh obair-lann, air a leantainn le smear iomaill agus pannal haemolysis dìreach ma mhaireas an àrdachadh no ma tha clàran-amhairc eile an làthair. Faodaidh òrdachadh a h-uile deuchainn anemia sa bhad barrachd fuaim a chruthachadh na freagairtean.
Tha sgrùdadh fìor-chiad loidhne a’ toirt a-steach ath-aithris CBC, sgrùdadh sgrìobadh sampall cealla, cunntas reticulocyte, bilirubin iomlan agus neo-dhìreach, LDH, haptoglobin, agus deuchainn antiglobulin dìreach nuair a tha haemolysis fèin-ìosal comasach. Faodaidh an smear spherocytes, agglutination, fragments, polychromasia, no morphology àbhaisteach a dh’ fhaodadh artifact a bhith nas dualtaich a chomharrachadh.
Ma mhaireas spherocytosis ginteil dualtach, dh’ fhaodadh hematologist beachdachadh air ceangal eosin-5-maleimide, deuchainn dìonachd osmotic, no deuchainn ginteil. Tha cunnartan mearachdach eadar-dhealaichte aig na deuchainnean sin às deidh tar-chur agus rè haemolysis geur, is e sin as coireach gum bu chòir òrdugh deuchainn a leantainn eachdraidh clionaigeach seach liosta bogsaichean; ar stiùireadh deuchainn G6PD a’ sealltainn an duilgheadas ùine nas fharsainge.
Bidh Kantesti AI a’ mìneachadh MCHC àrd le bhith a’ sgrùdadh an àireamhachadh an aghaidh comharran co-cheangailte ri CBC agus haemolysis, agus an uairsin a’ comharrachadh cheistean airson a thoirt gu neach-clionaigeach. Chan eil e a’ cur an àite sgrùdadh morphology cealla, gu sònraichte nuair a tha an obair-lann air brataich inneal-anailis a chuir a-mach no nuair a tha anemia a’ fàs nas miosa.
Cuin a tha MCHC àrd a’ feumachdainn measadh meidigeach èiginneach
Chan e stairsneach èiginn a th’ ann an MCHC àrd leis fhèin, ach faodaidh MCHC àrd le comharran haemolysis geur, anemia trom, no losgadh mòr a bhith a’ feumachdainn cùram an aon latha. Tha comharran agus an ìre atharrachaidh a’ dearbhadh èiginn fada nas fheàrr na bheil am brataich air a chomharrachadh H.
Iarr measadh èiginn airson giorrad analach ùr aig fois, pian broilleach, faochadh, troimh-chèile, laigse a tha a’ fàs gu luath, fual dath tì, no buidheachadh nan sùilean le fiabhras. Faodaidh na comharran sin a bhith an cois anemia no haemolysis cudromach, gu sònraichte nuair a tha hemoglobin air tuiteam le còrr air 2 g/dL bhon bhun-loidhne aithnichte.
Cuir fios chun neach-clionaigeach a dh’ òrduich an deuchainn taobh a-staigh làithean ma mhaireas MCHC os cionn 36 g/dL air sampall ath-aithris, tha anemia an làthair, no ma bheir an aithisg iomradh air agglutination no spherocytes. Ann an neach seasmhach, fallain le MCHC 36.2 g/dL agus toraidhean eile àbhaisteach, tha tarraing neo-èiginneach gu tric reusanta; ar stiùireadh pàtrain bilirubin faodaidh cuideachadh le bhith a’ cruthachadh an ath chòmhraidh.
Na tòisich air iarann, folate, steroids, no stuthan cur-ris dìreach airson MCHC a cheartachadh. Chan eil gin a’ làimhseachadh na prìomh adhbharan fìor, agus faodaidh steroids gu sònraichte an measadh air haemolysis fèin-ìosal a mhilleadh ma thèid an tòiseachadh gun stiùireadh clionaigeach.
Ciamar a chuireas Kantesti MCHC ann an co-theacs clionaigeach

Bidh mi a’ comhairleachadh euslaintich am PDF obair-lann, ceann-latha a’ chruinneachaidh, inbhe an traisg, tinneas o chionn ghoirid, eachdraidh tar-chuir fala agus beachdan obair-lann sam bith a shàbhaladh. Bidh an clàr beag sin gu tric a’ mìneachadh eas-aonta a tha coltach nas luaithe na bhith ag ath-dèanamh dheuchainnean fharsaing, gu h-àraidh nuair a thèid toraidhean a choimeas mìosan às dèidh sin.
Ceistean a nì coinneamh MCHC àrd nas toraidhe
Faighnich an deach an MCHC ath-dhearbhadh, an do mhothaich an obair-lann spherocytes no agglutination, agus a bheil anemia no comharran haemolysis an làthair. Bidh na ceistean sin a“ gluasad a” chòmhraidh bho “carson a tha aon àireamh àrd?” gu slighe chlinigeach chruaidh, a ghabhas dearbhadh le deuchainnean.
Am measg briathrachas feumail tha: “An robh an sampall haemolysed no lipemic?”, “An do chomharraich an anailisear agglutination cheallan dearga?”, agus “An urrainn dhuinn an toradh seo a choimeas ris an MCHC a bh” agam roimhe?” Tha sgrùdadh làimhe air smear gu sònraichte luachmhor nuair a tha MCHC a-rithist os cionn 36 g/dL no nuair nach eil adhbhar na h-anemia soilleir.
Tha an Dr Thomas Klein a’ moladh liosta de chungaidhean-leigheis, ghalaran o chionn ghoirid, chomharran air an adhbhrachadh le fuachd, eachdraidh teaghlaich de chlachan-gall no anemia, agus tar-chuiridhean fala anns na 3 mìosan roimhe a thoirt leat. Dh’fhaodadh an eachdraidh sin a bhith a’ comharrachadh spherocytosis oighreachail, haemolysis fèin-dìonach no agglutinin fuar sealach fada nas luaithe na rannsachadh coitcheann air-loidhne.
Tha susbaint mheidigeach Kantesti air ath-sgrùdadh fo stiùireadh lighiche, ach faodaidh an clionaigiche agad fhèin do sgrùdadh, ath-dheuchainn bhlàthaichte iarraidh agus bruidhinn gu dìreach ris an obair-lann. Faodaidh luchd-leughaidh a tha airson ar frèam ath-sgrùdaidh chlinigeach a thuigsinn coinneachadh ris an bòrd comhairleachaidh meidigeach, agus bu chòir ana-àbhaisteachdan leantainneach no samhlachail a bhith air an deasbad gu pearsanta an-còmhnaidh.
Rannsachadh, neo-chinnt, agus crìochan aon MCHC
Tha MCHC na chomharra sgrìonaidh feumail, chan e deuchainn breithneachaidh fa leth airson spherocytosis oighreachail, haemolysis fèin-dìonach, losgadh no galar agglutinin fhuar. Bidh a luach ag èirigh gu mòr nuair a bhios sampall ath-dhearbhaichte, morf-eòlas cheallan, comharran tionndaidh agus eachdraidh chlinigeach uile ag innse an aon sgeòil.
Chan eil gearradh-ìre uile-choitcheann MCHC ann a nì breithneachadh air spherocytosis oighreachail, oir faodaidh dòighean anailisear, aois, reticulocytosis agus easbhaidh iarainn co-aontach mothachalachd atharrachadh. Tha stiùireadh BSH a’ toirt taic do bhith a’ cothlamadh eachdraidh teaghlaich, toraidhean smear, reticulocytes, bilirubin agus deuchainnean dearbhaidh far a bheil feum, seach a bhith an urra ri aon stairsneach (Bolton-Maggs et al., 2012).
Tha Kantesti a’ toirt taic do leantainn fiosraichte le bhith a’ comharrachadh phàtranan thoraidhean agus mì-chinnt, chan ann le bhith a’ toirt seachad breithneachadh haemat-eòlach deimhinnte. Tha ar an dòigh-obrach airson dearbhadh clionaigeach a’ mìneachadh carson a tha luachan neo-àbhaisteach, brataichean anailisear agus comharraidhean èiginneach fhathast nan adhbharan airson ath-sgrùdadh le proifeiseantaich obair-lann agus clionaigiche.

Tha an dà chuid nam foillseachaidhean foghlaim a bharrachd, chan e luchd-àiteachaidh smear fala iomaill no measadh speisealaiche.
Ceistean Bitheanta
Dè tha ìre àrd MCHC ann an deuchainn fala a’ ciallachadh?
Tha ìre àrd MCHC mar as trice a' ciallachadh gu bheil dùmhlachd hemoglobin taobh a-staigh tomhas-lìonaidh cheallan fala dearga os cionn raon obair-lann, mar as trice os cionn 36 g/dL ann an inbhich. Bidh àrdachaidhean fìor a' tachairt le spherocytes bho spherocytosis oighreachail, anemia sèididh fèin-immine, no leòn mòr teas. Faodaidh fuasglaidhean fuar, lipemia, agus comharran sèididh fuil cuideachd toradh àrd meallta a chruthachadh. Faodaidh ath-aithris CBC, ath-sgrùdadh sleamhnan sampall cealla, agus comharran sèididh fuil soilleireachadh dè an mìneachadh a tha iomchaidh.
A bheil cunnart ann an MCHC àrd?
Chan eil MCHC àrd cunnartach leis fhèin; is e clàr-amais air a thomhas de CBC a th' ann seach tinneas. Bidh MCHC de 36.2 g/dL le hemoglobin àbhaisteach agus gun chomharran gu tric air a làimhseachadh le deuchainn ath-aithris àbhaisteach, ach feumaidh MCHC àrd a bharrachd air hemoglobin a tha a' tuiteam, buidheachas, fual dorcha, no anail gann measadh luath. Tha luachan os cionn 39 g/dL gu sònraichte dualtach beachdachadh air casg no buairidh air anailisear. Tha an cunnart clionaigeach a' tighinn bhon adhbhar bunaiteach, leithid fuasgladh mòr, chan ann bhon àireamh MCHC a-mhàin.
An urramasachd uisge air sgàth dìth uisgeachadh adhbhrachadh MCHC àrd?
Chan eil MCHC fìor àrd gu cumanta air adhbhrachadh le dìth uisge oir tha e a’ dùnadh sìos leabhar plasma nas motha na atharraicheas e dùmhlachd haemoglobin taobh a-staigh gach cealla dearg. Faodaidh dìth uisge haemoglobin agus hematocrit a thogail còmhla, a’ fàgail MCHC faisg air an raon àbhaisteach 32-36 g/dL. Mas e MCHC 37-40 g/dL, bu chòir do luchd-clionaigeach smaoineachadh air spherocytes, fuachd-chruinneachadh, lipaemia, no cùis tomhais nan àite. Tha CBC ath-thaghte a chaidh a chruinneachadh gu math nas feumail na bhith a’ feuchainn ris a’ luach a cheartachadh le lionnaichean a bharrachd.
An urrainnear spherocytes a dhèanamh gu sònraichte MCHC àrd?
Bidhidh cnàmhan gu tric ag àrdachadh MCHC os cionn 36 g/dL, ach chan eil iad an-còmhnaidh a’ dèanamh sin agus chan eil MCHC àrd a’ dearbhadh gu bheil cnàmhan an làthair. Faodar spherocytosis oighreachail fhalach le dìth iarainn, tar-chur o chionn ghoirid, no galar tlàth, fhad ‘s a dh’ fhaodadh sèid fèin-mhillteach a bhith a’ sealltainn toraidhean caochlaideach a rèir ùine. Tha feum air sampall cheallan air a sgrùdadh le proifeasanta obair-lann le eòlas gus cnàmhan a chomharrachadh. Tha cunntas reticulocyte, bilirubin, LDH, haptoglobin, agus deuchainn dìreach antiglobulin a’ cur ri co-theacsa breithneachaidh.
An urrainnear fuachd-ghlùinean a bhith a' cur MCHC àrd?
Faodaidh cruinneagan fuar MCHC a thogail gu mearachd le bhith a’ cruinneachadh cheallan dearga mus tomhaisear an CBC fèin-ghluasadach. Gu tric tha an clàr a’ toirt a-steach àireamh RBC ìosal, MCV àrd, MCH àrd, agus MCHC os cionn 36 g/dL nach eil a’ freagairt air comharraidhean an euslaintich. Faodaidh blàthachadh an sampall EDTA gu 37°C agus ath-ruith e na cunntasan a dhèanamh àbhaisteach. Bu chòir cruinneachadh fuar leantainneach no comharraidhean de cheall-leagadh a bhith air am measadh le clionaigiche no hematologist.
Dèuchainnean sam bu chòir dhomh iarraidh às dèidh MCHC àrd?
An dèidh MCHC àrd leantainneach, is iad na deuchainnean àbhaisteach a leanas ath-dheuchainn CBC, ath-sgrùdadh sleamhnan sampall cealla, cunntas reticulocyte, roinnean bilirubin, LDH, haptoglobin, agus uaireannan deuchainn dìreach antiglobulin. Faodaidh neach-clionaigeach iarradh ceangal eosin-5-maleimide no deuchainnean sònraichte eile ma tha amharas air spherocytosis oighreachail. Is dòcha nach fheum MCHC os cionn 36 g/dL le ath-dheuchainn àbhaisteach agus gun anemia sgrùdadh farsaing. Tha an t-sreath deuchainn as fheàrr an urra ri comharran, luachan CBC roimhe, eachdraidh teaghlaich, agus brataichean obair-lann.
