Nizak broj trombocita ponekad može biti greška u mjerenju povezana s epruvetom, a ne problem unutar vašeg tijela. Evo kako se pseudotrombocitopenija povezana s EDTA identificira prije nego što vam se dijagnosticira trombocitopenija.
- Pseudotrombocitopenija je lažno nizak broj trombocita uzrokovan lijepljenjem trombocita nakon uzimanja, najčešće u EDTA epruveti.
- Tipičan raspon trombocita za većinu odraslih osoba koje nisu trudne iznosi približno 150-450 × 10⁹/L, iako laboratorije postavljaju vlastite intervale.
- Nakupine trombocita na razmazu mogu uzrokovati da automatski analizator podcjenjuje trombocite jer se nakupina ne mjeri kao zasebne stanice.
- Ponovno uzimanje krvi s citratom često rješava lijepljenje trombocita u EDTA; laboratorije obično primjenjuju korekciju razrjeđenja od 1,1 na brojanje trombocita s citratom.
- Nema simptoma krvarenja plus neočekivano izolirani nizak broj trombocita trebao bi potaknuti pregled razmaza prije liječenja ili hitnih uputnih odluka.
- Prava trombocitopenija se može javiti istovremeno sa aglutinacijom trombocita u EDTA epruveti, tako da je normalan rezultat iz citrate umirujući, ali mora odgovarati kliničkoj slici.
- Potrebna je hitna procjena je i dalje potreban kod nekontrolisanog krvarenja, novih raširenih petehija, jakih glavobolja, konfuzije ili kada je broj trombocita ispod 10 × 10⁹/L.
Što zapravo znači lijepljenje trombocita u EDTA
Aglutinacija trombocita u EDTA epruveti je in vitro laboratorijski artefakt u kojem se trombociti lijepe jedni za druge u epruveti za prikupljanje, što uzrokuje lažno nizak automatski broj trombocita. Sam po sebi ne znači da se trombociti uništavaju u tijelu i obično ne stvara rizik od krvarenja.
EDTA je aditiv u epruveti sa ljubičastim čepom koji se koristi za većinu kompletnih krvnih slika jer vezuje kalcijum i sprečava koagulaciju. Kod malog broja ljudi, uklanjanje kalcijuma izlaže površinske ciljeve trombocita koji omogućavaju prirodno prisutnim antitijelima da povežu trombocite. Analizator može prebrojati klaster trombocita kao jednu veliku česticu, događaj veličine bijele krvne ćelije, ili uopšte ništa; pogledajte naš pregled šta uključuje CBC.
U svom kliničkom radu, klasičan nalaz je broj trombocita od 48 × 10⁹/L kod nekoga ko se osjeća potpuno dobro, nema modrice i ima normalan hemoglobin i broj bijelih krvnih zrnaca. Ta nesaglasnost nije dokaz, ali je trenutak za zastajanje. Kantesti je AI analizator krvi koji signalizira izolovani nizak broj trombocita uz laboratorijske komentare kao što su agregati trombocita, umesto da se broj tretira kao dijagnoza.
EDTA-zavisna pseudotrombocitopenija se procjenjuje kod otprilike 0,03-0,27% rutinskih ambulantnih uzoraka, sa višim stopama među uzorcima koji su već upućeni zbog niskog broja trombocita. Lippi i kolege opisuju to kao klinički bezopasan, ali potencijalno značajan preanalitički fenomen jer može dovesti do nepotrebnih hospitalizacija, transfuzija trombocita ili steroidne terapije (Lippi et al., 2012).
Kako analizatori trombocita mogu podcijeniti zalijepljene uzorke
Automatski brojači trombocita su pouzdani za raspršene trombocite, ali klasteri izlaze izvan očekivanih veličina i obrazaca signala analizatora. Broj se stoga može smanjiti sa stvarnih 220 × 10⁹/L na prividnih 40 × 10⁹/L bez ikakvog biološkog gubitka trombocita.
Impedancioni analizatori klasifikuju čestice uglavnom po zapremini, dok optički sistemi dodaju informacije o rasejanju svetlosti. Trombocit je obično širok oko 2-3 mikrometra, ali klaster može preklapati fragment crvenih krvnih zrnaca ili leukocitnu regiju. Zato histogram trombocita može biti abnormalan i zašto laboratorija može dodati “prisutni klasteri trombocita” ili “broj nepouzdan”.”
Signal za trombocite analizatora je podsticaj za ljudsku reviziju, a ne konačna dijagnoza. Ručna procjena iz dobro napravljenog razmaza periferne krvi može biti korisnija nego ponavljanje iste EDTA epruvete, posebno ako je uzorak stajao 2 sata prije analize. Za praktične pragove oko procedura, naš vodič za broj trombocita pre vađenja zuba objašnjava zašto je potvrđen rezultat važan.
Veliki trombociti stvaraju drugačiji, ponekad preklapajući problem. Vrlo veliki pojedinačni trombociti mogu biti propušteni impedancionim metodama čak i bez vidljivih klastera, često povećavajući prosječnu zapreminu trombocita (MPV). Visok MPV nije zamjenjiv sa pseudotrombocitopenijom; naš pregled uzroci velikih trombocita razdvaja ova dva nalaza.
Kako izgledaju nakupine trombocita na razmazu
Klasteri trombocita na razmazu izgledaju kao nepravilne grupe malih ljubičastih zrnastih elemenata nalik grožđu, često koncentrisane na perastom rubu stakalca. Njihova lokacija je bitna jer brojanje samo centralnog polja razmaza može propustiti upravo onu karakteristiku koja objašnjava nizak rezultat.
Obučeni morfolog pregleda tijelo i rep razmaza pod velikim povećanjem, ne samo jedno reprezentativno polje. Trombocitni satelitizam je rjeđi EDTA-udruženi obrazac u kojem trombociti okružuju neutrofile poput rozete; također može sniziti prijavljeni broj trombocita. Oba nalaza su pojave uzorka, iako se satelitizam i široki agregati povremeno mogu javiti zajedno.
Jedan koristan detalj je da se aglutinacija u EDTA epruveti često pojačava s vremenom. Uzorak mjeren 10 minuta nakon uzimanja može pokazati 118 × 10⁹/L, a zatim 42 × 10⁹/L nakon 90 minuta kako se formira više agregata. Laboratorije se razlikuju po svom radnom toku, tako da normalan početni broj ne isključuje u potpunosti ovaj artefakt ako se pojavi kasniji signal analizatora.
When I, Thomas Klein, MD, see a low count paired with a smear comment but no clinical bleeding, I ask for the actual smear interpretation before discussing immune thrombocytopenia. Similar microscopy-first reasoning is useful when a report mentions schistocytes on a blood film, although schistocytes require a much more urgent clinical context.
Zašto EDTA uzrokuje nakupine trombocita kod nekih ljudi
EDTA can trigger platelet clumping by chelating calcium and changing the shape of platelet membrane glycoproteins, allowing antibodies to bind and bridge neighboring platelets. This reaction occurs after collection, not because EDTA has harmed circulating platelets inside the body.
The best-supported mechanism involves antibodies, often IgG, IgM, or IgA, recognizing cryptic sites on the platelet GPIIb/IIIa complex after calcium-dependent structural change. The reaction is temperature and time dependent in some patients, which explains why a warmed sample can occasionally improve counting but is not a universal fix. It is a laboratory compatibility issue, not an allergy to EDTA.
Pseudothrombocytopenia can occur in healthy people and has been reported alongside autoimmune conditions, infections, malignancy, and pregnancy, but those associations do not establish causation in an individual. A positive ANA or a recent viral illness should not be used to explain the count until the artifact is excluded. Kantesti is an AI platforma za tumačenje krvne slike that reads a platelet result with its tube type, analyzer flags, and the rest of the CBC rather than in isolation.
The phenomenon may persist for years yet vary between draws. A patient can have a platelet count of 35 × 10⁹/L in EDTA on Monday and 230 × 10⁹/L in citrate the same morning, then show partial clumping again months later. Recording the preferred tube in the laboratory record can prevent repeated alarms.
Kako ponovno uzimanje krvi s citratom potvrđuje pseudotrombocitopeniju
A platelet count that normalizes in a sodium citrate tube while the EDTA tube contains aggregates strongly supports EDTA-dependent pseudothrombocytopenia. The citrate count needs a dilution adjustment because the tube contains liquid anticoagulant.
Blue-top sodium citrate tubes are generally filled at a 9:1 blood-to-anticoagulant ratio. Many laboratories multiply the measured citrate platelet count by 1.1 to correct for dilution, though the local laboratory's validated method takes precedence. For example, a raw citrate result of 182 × 10⁹/L becomes about 200 × 10⁹/L after correction.
The redraw must be properly filled and gently mixed. An underfilled citrate tube changes the anticoagulant ratio and can create a different misleading result, which is one reason a laboratory scientist may reject an apparently simple repeat. Our explanation of blood test tube colors helps patients recognize why the tube choice is part of the test method.
Magnesium sulfate or acid-citrate-dextrose tubes can be useful when clumping continues in citrate, but this is usually a laboratory-directed decision. Nagler and colleagues documented a case in which recognition of EDTA-dependent pseudothrombocytopenia avoided an unnecessary diagnostic work-up after citrate testing showed an adequate count (Nagler et al., 2014).
Kada brojanje trombocita s citratom ne razjašnjava pitanje
A citrate redraw does not rule out true thrombocytopenia when the corrected count remains low, clumping occurs in more than one anticoagulant, or symptoms suggest bleeding. Some patients have multi-anticoagulant platelet aggregation, and some have a real low count alongside an artifact.
If the corrected citrate platelet count is 82 × 10⁹/L and the smear is free of clumps, that is genuine thrombocytopenia until proven otherwise. If EDTA is 25 × 10⁹/L and citrate is 86 × 10⁹/L with residual aggregates, both an artifact and a true reduction may be present. The clinical team should use the best verified estimate, not simply choose the more reassuring number.
Clotting in the specimen can also invalidate a CBC because platelets are consumed within the microclot. Unlike EDTA pseudothrombocytopenia, a partially clotted specimen may affect white cells and red-cell indices as well. Read our redraw guide after sample problems for the practical differences between collection artifacts.
Finger-prick samples are not automatically safer. Slow collection, squeezing, or delayed mixing can promote local aggregation and compromise a platelet count, particularly when the reported value is below 100 × 10⁹/L. Venous recollection with prompt processing is usually the cleaner confirmation route.
Rasponi broja trombocita, rizik od krvarenja i zamka artefakta
Most adult laboratories use a platelet count reference interval near 150-450 × 10⁹/L, but bleeding risk depends on the verified count, its cause, platelet function, and medications. A falsely low EDTA result must not be used alone to deny a procedure or prescribe treatment.
Spontaneous major bleeding becomes more likely as a true platelet count falls below about 10 × 10⁹/L, while many people with stable counts above 50 × 10⁹/L have little spontaneous bleeding. These are broad clinical guideposts, not permission to ignore symptoms. Anticoagulants, aspirin, liver disease, kidney failure, and platelet dysfunction can alter the risk at any number.
A platelet count of 90 × 10⁹/L deserves different handling in a well person with a normal citrate result than in someone with new melena and an elevated INR. That is why platelet count interpretation belongs beside coagulation testing; our aPTT and clotting test guide explains what a normal clotting screen can and cannot exclude.
Laboratories may use 140 × 10⁹/L rather than 150 × 10⁹/L as the lower reference limit, particularly with locally derived intervals. A reference interval describes 95% of a comparator population; it does not define a universal treatment threshold. This distinction saves a surprising amount of unnecessary worry.
CBC obrasci koji čine artefakt vjerojatnijim
An isolated unexpectedly low platelet count with normal hemoglobin, white cells, and a clumping comment is the CBC pattern most suggestive of pseudothrombocytopenia. This pattern is suggestive rather than diagnostic because early immune or drug-related thrombocytopenia may also be isolated.
True marrow disorders often alter more than one blood-cell line, although exceptions exist. Low platelets combined with falling hemoglobin, abnormal white cells, blasts, or persistent constitutional symptoms calls for prompt clinician review and often a formal film examination. Our article on the CBC pathway for blood disorders outlines why these clusters change the urgency.
The platelet-to-lymphocyte ratio can become meaningless when the denominator is valid but the platelet numerator is artificially depressed. A PLR of 60 calculated from an EDTA-clumped count should not be interpreted as an inflammatory or cardiovascular signal. This is a quiet but common secondary error in automated health reports; see our explanation of high PLR results.
Kantesti AI identifies discordance between a low platelet count and normal neighboring CBC measures, then directs the reader to verify sample comments. An Alat za analizu krvnih nalaza uz pomoć AI-a should never convert a single unverified platelet value into a disease label. That clinical restraint matters more than speed.
Trudnoća, bolnička njega i druga okruženja s visokim ulozima
EDTA platelet clumping can occur during pregnancy and hospital care, but it must never be assumed when true thrombocytopenia could change urgent management. Pregnancy-specific causes such as gestational thrombocytopenia, pre-eclampsia, HELLP syndrome, and immune thrombocytopenia require a verified count.
Platelet counts commonly drift downward in uncomplicated pregnancy, and some laboratories accept lower trimester-specific reference limits. A count below 100 × 10⁹/L is less typical for uncomplicated gestational thrombocytopenia and merits a careful clinical assessment, even if EDTA aggregates are seen. Our trimester-specific platelet reference guide in pregnancy gives context without replacing obstetric review.
In hospital, a sudden fall of more than 50% from baseline may raise questions about sepsis, drug exposure, heparin-induced thrombocytopenia, dilution, or device-related consumption. An EDTA artifact can mimic a dramatic decline, especially when a previous result came from a different laboratory method. Comparing a verified citrate result with the patient's baseline is often more useful than repeating a routine EDTA CBC.
Before an epidural, surgery, chemotherapy cycle, or platelet transfusion, ask whether the laboratory has confirmed the value on a smear or alternative anticoagulant. I have seen delays in care avoided by that one phone call. Conversely, active symptoms or an unstable patient should be assessed while confirmation is underway.
Lijekovi i dijagnoze za koje ne treba prerano kriviti
EDTA platelet clumping should be excluded before attributing an isolated low platelet count to a medicine, autoimmune disease, or immune thrombocytopenia. Stopping a valuable medication on the basis of an unverified count can cause avoidable harm.
Heparin, quinine-containing products, trimethoprim-sulfamethoxazole, valproate, linezolid, chemotherapy, and some immune therapies can cause real thrombocytopenia. The time relationship matters: a genuine drug-associated fall typically persists in a properly collected citrate sample and does not vanish when EDTA is replaced. A medication history should include injections, over-the-counter products, and herbal preparations.
Immune thrombocytopenia is a diagnosis of exclusion, not a laboratory flag. It can present with isolated platelets below 100 × 10⁹/L, but a clumped EDTA smear makes the initial count uninterpretable. Lippi et al. (2012) specifically caution that recognizing pseudothrombocytopenia prevents inappropriate therapies such as corticosteroids and splenectomy.
If a report appears to contradict your prior results, preserve the original PDF and note the collection date, tube comment, acute illness, and new medicines. Our guide to značajnim promjenama između krvnih testova explains why a numerical delta is not automatically a biological change.
Što pitati svoju laboratoriju ili kliničara sljedeće
For an unexpected low platelet count, ask whether platelet clumps were seen, whether a peripheral smear was reviewed, and whether an alternative-anticoagulant count can be performed. Those three questions usually clarify the next step faster than searching for symptoms online.
A practical request is: “Could the laboratory review the blood film for platelet aggregates and, if needed, repeat the platelet count in citrate?” This is not demanding a particular diagnosis; it is asking that the measurement be validated. If the sample was collected elsewhere, the clinician may need to order a new draw rather than add testing to an old tube.
Zatražite ispravljen citrate result and whether clumps persist in that tube. A raw result of 145 × 10⁹/L may look borderline until dilution correction gives approximately 160 × 10⁹/L. Also ask whether the laboratory used an optical or fluorescence platelet count, as these methods sometimes improve enumeration in complex samples.
Kantesti's 2026 interpretation workflow encourages users to compare the numerical result with the laboratory narrative and flag fields before acting on an alert. For a broader safety framework, our kontrolni spisak tačnosti AI izvještaja covers transcription, units, reference ranges, and result verification.
Što ne raditi dok čekate potvrdu
Do not start supplements, stop prescribed medicines, or assume you have a bleeding disorder solely because one EDTA platelet count is low. At the same time, do not dismiss active bleeding just because clumping is suspected.
There is no diet, vitamin, or home remedy that corrects EDTA-dependent pseudothrombocytopenia because the platelets are clumping in the tube, not failing inside the body. Folate, vitamin B12, and iron deficiency can affect blood formation in other settings, but supplements cannot validate a questionable count. Treating the artifact is about collection and analysis.
Avoid non-essential aspirin, ibuprofen, naproxen, and heavy alcohol intake until a clinician has clarified a very low reported count, particularly if you bruise easily. Do not stop anticoagulants, antiplatelet medicines, antiseizure drugs, or cancer treatments without prescriber advice; the indication for those medicines may carry greater immediate risk than the unverified result.
Keeping a concise result timeline can change the appointment. Our lab result tracking guide suggests recording draw time, recent illness, medicines, sample comments, and whether the result came from EDTA or citrate.
Crvene zastavice koje zahtijevaju hitnu medicinsku procjenu
Seek urgent medical assessment for uncontrolled bleeding, black stools, vomiting blood, a severe new headache, confusion, fainting, or widespread pinpoint rash, even if EDTA clumping is suspected. A laboratory artifact and a genuine emergency can coexist.
A true platelet count below 10 × 10⁹/L is generally treated as an urgent result because spontaneous mucosal and internal bleeding risk rises substantially. A count below 20 × 10⁹/L with new bleeding, fever, severe hypertension, pregnancy complications, or recent heparin exposure also deserves same-day clinician input. Local emergency advice should take priority over any online interpretation.
New neurological symptoms are particularly significant because intracranial bleeding is uncommon but serious. Do not drive yourself if you have severe headache with weakness, speech change, collapse, or confusion. In children, a non-blanching rash with fever needs urgent assessment regardless of the platelet result.
Thomas Klein, MD, advises patients to separate the question “Is this count real?” from “Is this person safe today?” The first usually needs a smear and citrate redraw; the second depends on symptoms, exam findings, and the whole clinical picture. Our vodič za drugo mišljenje o krvnom testu can help prepare a focused discussion after urgent issues are addressed.
Kako Kantesti sigurno tumači obilježeni broj trombocita
Kantesti AI treats a low platelet count with EDTA clumping comments as a verification signal, not as proof of thrombocytopenia. Our interpretation places analyzer flags, the other CBC lines, prior values, and reported symptoms ahead of a simplistic red-or-green label.
Kantesti je usluzi za tumačenje laboratorijskih testova AI designed to explain laboratory data in plain language while preserving the limits of the source report. If an uploaded PDF states “platelet clumps,” our system should tell the user that the number may be falsely low and that the laboratory or clinician can confirm it with a film review or citrate sample.
Optical character recognition can misread a decimal point, a unit, or a laboratory footnote. That is why patients should inspect the image preview before relying on any digital interpretation, particularly around values such as 18 versus 180 × 10⁹/L. Our kontrolnom spisku za kvalitet PDF upload-a explains the few checks that prevent most avoidable errors.
Clinical oversight remains human work. Kantesti's methodology is reviewed against safety-focused workflows; readers who want to understand our approach can review our tehnička validacija i klinički nadzor. AI can organize questions efficiently, but it cannot inspect the actual smear or assess active bleeding.
Praktični plan praćenja nakon lijepljenja trombocita u EDTA
The usual follow-up plan is to document the EDTA artifact, obtain a verified alternative-tube platelet count, and use that result for future clinical decisions. Most people need no treatment for the artifact itself once the laboratory has established the pattern.
Ask for the laboratory record to note “EDTA-dependent platelet clumping” or equivalent wording if confirmation is clear. On future draws, the phlebotomy team may collect a citrate tube alongside the routine EDTA CBC, saving a second appointment. This is especially useful before surgery, during pregnancy, or when a treatment protocol has platelet thresholds.
A verified baseline is more valuable than repeated unverified low values. If your corrected citrate count is stable at 205 × 10⁹/L over 12 months, a future EDTA value of 55 × 10⁹/L with aggregates is far less alarming than the same number in someone without prior documentation. Trends are useful only when the testing method is comparable.
Kantesti has supported more than 2 million users across 127+ countries with multilingual laboratory explanations, but results still belong in the care relationship with your clinician. Our medical reviewers and Medicinski savjetodavni odbor emphasize the same final rule: verify the platelet count first, then decide what—if anything—needs treatment.
Istraživačke publikacije
As of August 29, 2026, the two Kantesti research publications listed below are supplementary educational resources. They do not establish the diagnosis of EDTA-dependent pseudothrombocytopenia; the laboratory smear and alternative-anticoagulant platelet count remain the relevant confirmation tools.
Često postavljana pitanja
Može li zgrudnjavanje trombocita izazvano EDTA uzrokovati vrlo nizak broj trombocita?
Da. Aglutinacija trombocita izazvana EDTA-om može dati znatno lažno nizak broj trombocita, ponekad ispod 50 × 10⁹/L, iako je stvarni broj cirkulirajućih trombocita osobe normalan. Analizator broji agregate trombocita, ali ne može pouzdano prepoznati svaki trombocit unutar nakupine. Pregled periferne krvi koji pokazuje agregate i normalan korigovani citratni broj snažno podupiru pseudotrombocitopeniju. Rezultat bi i dalje trebalo hitno pregledati ako postoji aktivno krvarenje ili ako citratni broj ostaje nizak.
Kako se potvrđuje pseudotrombocitopenija?
Pseudotrombocitopenija se obično potvrđuje pregledom razmaza periferne krvi na agregate trombocita i ponavljanjem broja trombocita u epruveti sa natrijum citratom. Citratne epruvete sadrže tečni antikoagulant, tako da mnoge laboratorije množe izmereni broj trombocita sa 1.1 kako bi uzele u obzir razređenje. Na primer, sirovi citratni broj od 180 × 10⁹/L se nakon korekcije obično izveštava kao približno 198 × 10⁹/L. Validna korekcija lokalne laboratorije i interpretacija razmaza treba da vodi konačnom rezultatu.
Znači li aglutinacija trombocita u EDTA da imam poremećaj krvarenja?
Ne. Agregacija trombocita u EDTA epruveti sama po sebi predstavlja artefakt in vitro uzorka i ne znači da imate poremećaj krvarenja ili da vam se trombociti agregiraju u cirkulaciji. Većina pogođenih osoba nema simptome krvarenja i ima potvrđen broj trombocita unutar uobičajenog odraslog intervala od oko 150-450 × 10⁹/L. Kliničar bi i dalje trebao istražiti simptome krvarenja, abnormalne koagulacione testove ili uporno nizak broj trombocita u citratnoj epruveti. Artefakt ne štiti osobu od nepovezanih rizika krvarenja uzrokovanih lijekovima ili medicinskim stanjima.
Može li do zgrudnjavanja trombocita doći i u citratu?
Da, iako natrijum-citrat često sprečava zgrudnjavanje povezano sa EDTA, agregacija trombocita se povremeno može zadržati u citratu ili nastati sa više antikoagulanasa. U takvoj situaciji, laboratorija može koristiti optički ili fluorescencijski broj trombocita, brzu obradu na toplom, magnezijum sulfat ili acid-citrat-dekstrozu, zavisno od svojih validiranih protokola. Korigovani broj trombocita u citratu ispod 150 × 10⁹/L bez agregata treba smatrati mogućom pravom trombocitopenijom. Zgrudnjavanje sa više antikoagulanasa je retko i zahteva potvrdu pod laboratorijskim nadzorom.
Trebam li ponoviti broj trombocita ako u nalazu piše da postoje aglomerati trombocita?
Da. Izvještaj koji navodi nakupine trombocita, agregate trombocita ili nepouzdano brojanje trombocita općenito opravdava provjeru, a ne prihvaćanje brojčanog rezultata. Uobičajeno ponovno testiranje je svježe prikupljeni uzorak natrij citrata s pregledom razmaza, po mogućnosti obrađen promptno. Ako je prvobitni broj ispod 10 × 10⁹/L ili imate nekontrolirano krvarenje, crnu stolicu, jaku glavobolju ili konfuziju, potražite hitnu medicinsku pomoć dok se potvrda organizira. Nemojte mijenjati propisane lijekove bez savjeta kliničara koji zna zašto su propisani.
Da li EDTA pseudotrombocitopenija može da dolazi i odlazi?
Da. EDTA pseudotrombocitopenija može biti perzistentna godinama ili se pojavljivati varijabilno jer stepen aglutinacije zavisi od vremena nakon uzorkovanja, temperature uzorka i metode analizatora. Jedan EDTA uzorak može pokazati 70 × 10⁹/L, dok drugi prikupljen drugog dana pokazuje 145 × 10⁹/L, uprkos stabilnom stvarnom broju trombocita. Dokumentovani normalan citratni nalaz pruža korisnu osnovicu za buduću usporedbu. Traženje od laboratorije da zabilježi preferirani antikoagulans može spriječiti ponovljene lažne uzbune.
