Visok broj RBC može ukazivati na koncentrovanu krv, a ne na povećan broj crvenih krvnih zrnaca. Prvi zadatak je razlikovanje privremenog gubitka tečnosti od perzistentnog povišenja koje zahteva odgovarajuću dijagnostiku.
- Relativna eritrocitoza znači da je količina plazme opala, čineći da broj RBC, hemoglobin i hematokrit izgledaju povišeno bez stvaranja novih ćelija.
- WHO праг vrednosti koje podržavaju moguću policitemiju veru su hemoglobin iznad 16,5 g/dL kod muškaraca ili 16,0 g/dL kod žena, odnosno hematokrit iznad 49% i 48%.
- Ponovno testiranje nakon hidratacije je obično razumno kod blagog, izolovanog povišenja nakon povraćanja, dijareje, izlaganja vrućini, posta ili napornog vežbanja — ukoliko se inače osećate dobro.
- Диуретици može povećati hematokrit usled gubitka tečnosti; ne prekidajte uzimanje propisanih lekova bez konsultacije sa lekarom koji ih je prepisao.
- образац је важан: visok albumin, ukupni proteini, natrijum, odnos BUN/kreatinin i specifična težina urina više podržavaju dehidrataciju nego pravu prekomernu proizvodnju crvenih krvnih zrnaca.
- Понављање у одређеним интервалима je obično 1–2 nedelje nakon oporavka, normalnog unosa tečnosti i 24–48 sati bez neuobičajeno napornog vežbanja, osim ako nisu prisutni hitni simptomi.
- упорно повишен nakon dobre hidratacije zahteva procenu izloženosti pušenju, poremećaja disanja u snu, nadmorske visine, testosterona, bolesti pluća ili bubrega, eritropoetina i često JAK2 testiranje.
- Хитни симптоми uključuju bol u grudima, novonastali nedostatak vazduha, slabost jedne strane tela, gubitak vida, konfuziju ili bolnu otečenu nogu; ovo zahteva hitnu negu, a ne ponovno testiranje kod kuće.
Šta obično znači visok rezultat RBC
Visok RBC broj može biti lažno visok usled dehidratacije kada gubitak tečnosti koncentriše ćelijski deo krvi; to ne znači automatski da vaša koštana srž proizvodi previše crvenih krvnih zrnaca. Trag je u tome da li se hemoglobin i hematokrit normalizuju nakon oporavka i uobičajenog unosa tečnosti, umesto da ostanu povišeni na pravilno pripremljenom ponovljenom CBC.
RBC broj izveštava o broju crvenih krvnih zrnaca po litru, dok хематокрит izveštava o udelu pune krvi koji zauzimaju te ćelije. Referentni intervali za odrasle se razlikuju u zavisnosti od laboratorije, ali mnogi koriste približno 4,5–5,9 × 10¹²/L za muškarce i 4,1–5,1 × 10¹²/L za žene. Vrednost neznatno iznad opsega često je manje informativna od hemoglobina i hematokrita pored nje; naš vodič za šta obuhvata CBC објашњава зашто.
Dehidratacija smanjuje tečnu komponentu krvi u roku od nekoliko sati, pa ista masa crvenih krvnih zrnaca zauzima manju izmerenu zapreminu. U klinici to često viđam nakon stomačnog virusa: RBC 5,8 × 10¹²/L, hemoglobin 17,1 g/dL, hematokrit 51%, zatim normalne vrednosti nakon oporavka. Ovo je relativna eritrocitoza, a ne laboratorijska greška i nije nužno bolest.
Кантести је АИ анализатор крви koji zajedno tumači RBC, hemoglobin, hematokrit, indekse crvenih krvnih zrnaca, bubrežne markere i prethodne rezultate. Od 5. septembra 2026. godine, naš radni proces kliničkog pregleda tretira jedno granično upozorenje CBC kao poziv da se proveri priprema i trend—a ne kao dijagnozu.
RBC broj nije isto što i masa crvenih krvnih zrnaca
CBC ne može direktno da izmeri ukupnu masu crvenih krvnih zrnaca. On meri koncentraciju, koja raste kada se smanji zapremina plazme; specijalizovane studije izotopa za merenje mase crvenih krvnih zrnaca su danas retko potrebne, ali one ilustruju zašto koncentrisan CBC može izgledati alarmantno bez stvarnog povećanja broja ćelija.
Relativna eritrocitoza naspram pravog viška crvenih krvnih zrnaca
Relativna eritrocitoza je visok RBC, hemoglobin ili hematokrit uzrokovan smanjenom zapreminom plazme, dok apsolutna eritrocitoza odražava stvarno povećanu masu crvenih krvnih zrnaca. Hidratacija može ispraviti prvi obrazac, ali neće ispraviti drugi.
Prava eritrocitoza može biti primarna, kao kod policitemije vere, ili sekundarna usled povećanog eritropoetina zbog niskog nivoa kiseonika, lekova ili, retko, procesa u bubrezima. Kriterijumi SZO iz 2016. koriste hemoglobin iznad 16,5 g/dL kod muškaraca ili 16,0 g/dL kod žena kao pragove koji bi trebalo da otvore pitanje policitemije vere, posebno kada je stanje perzistentno (Arber i dr., 2016). Jedna vrednost nije dovoljna za dijagnozu.
Praktična razlika se ogleda u ostatku panela. Dehidratacija visok RBC broj obrasci često uključuju visok albumin, ukupne proteine, ureu/BUN, natrijum i koncentrovanu mokraću; apsolutna eritrocitoza može ostaviti ove markere nepromenjenim. Pregledajte naš fokusirani članak o blago povišenom hemoglobinu ako je hemoglobin, a ne samo RBC, rezultat koji je označen.
Normalan RBC broj ne isključuje eritrocitozu ako su hemoglobin ili hematokrit visoki, a povišen RBC broj sam po sebi može se javiti uz sitna crvena krvna zrnca usled nedostatka gvožđa ili talasemije minor. Zbog toga su MCV i feritin važni; visok RBC uz MCV ispod 80 fL je drugačija klinička priča.
Kako dehidratacija menja CBC i bubrežne markere
Dehidratacija obično podiže RBC broj, hemoglobin i hematokrit istovremeno, a često podiže i albumin, ukupne proteine, ureu/BUN, kreatinin i koncentraciju mokraće. Neslaganje rezultata—na primer, visok RBC uz nizak hemoglobin—ne odgovara dobro jednostavnoj hemokoncentraciji.
A BUN/creatinine ratio above about 20:1 in US units can support reduced kidney perfusion from fluid loss, although gastrointestinal bleeding, protein intake, corticosteroids, and low muscle mass can alter the ratio. Creatinine may rise modestly after heat exposure or a long run because both filtration and muscle metabolism change. Our vodič za dehidrataciju i eGFR covers when a low eGFR should be repeated.
Urine specific gravity of 1.025 or higher is compatible with concentrated urine, but it is not a direct hydration meter. Glucose, protein, and some imaging contrast agents can also increase it, so a clinician should interpret it with symptoms and electrolytes. A urine specific gravity reference is useful when the CBC and urinalysis were collected on the same day.
I advise against trying to force-normalise a test by drinking several litres immediately before a draw. Rapid overdrinking can lower sodium, and it creates another unrepresentative sample; normal meals and ordinary thirst-guided fluids for 24–48 hours are generally safer for people without a fluid restriction.
Povraćanje, dijareja, vrućina, post i diuretici
Vomiting, diarrhea, heavy sweating, prolonged fasting, and diuretic medicines can all cause a temporary high RBC concentration by reducing plasma water. The degree of elevation depends more on fluid loss and replacement than on how unwell a person feels.
Acute vomiting often produces low chloride and sometimes high bicarbonate because gastric acid and fluid are lost. Loop diuretics such as furosemide and thiazides can produce a similar volume-contracted profile, especially in older adults. A low chloride result belongs in the same clinical frame; see vomiting and diuretic chloride clues obrazac.
Do not stop a prescribed diuretic to improve a CBC without medical advice. People taking these medicines for heart failure, cirrhosis, resistant hypertension, or kidney disease may need a tailored fluid plan, because indiscriminate drinking can worsen swelling or breathlessness. The right question is whether the dose, symptoms, weight, blood pressure, and renal results fit together.
Thirst is helpful but imperfect in adults over 65 and in people with diabetes, kidney disease, or certain neurological conditions. Dark yellow urine, dry mouth, postural light-headedness, reduced urination, and a weight drop of 1 kg over 24 hours can support fluid loss, but severe symptoms deserve assessment rather than self-treatment.
Vežbanje može privremeno da koncentriše vašu krv
Hard endurance exercise can raise hematocrit and hemoglobin for several hours through sweat loss and plasma-volume shifts, even though repeated training may lower baseline hematocrit through expanded plasma volume. Timing is therefore unusually important for athletes.
A 90-minute run in warm weather can remove 1–3 litres of fluid, depending on body size, climate, and sweat rate. Sampling immediately after a race may also show higher creatinine, CK, albumin, and total protein; that cluster is more useful than an RBC result alone. Our marathon blood-test timing guide discusses the recovery markers that commonly change.
For routine monitoring, I usually suggest avoiding unusually intense exercise for 24–48 сати before the draw, arriving rested, and drinking normally the day before. This is not a universal laboratory rule, and elite-athlete monitoring may deliberately test under load—but consistency matters more than perfection. Dr. Thomas Klein has seen many unnecessary referrals disappear once an athlete is retested after a normal recovery week.
Kantesti’s Istraživački vodič za BUN i kreatinin is particularly helpful when an endurance athlete has both a high hematocrit and a borderline kidney flag. A falling weight, high urine specific gravity, and short recovery interval make hemoconcentration plausible; muscle pain, cola-coloured urine, or very high CK require a different level of caution.
Bezbedan plan za ponavljanje blago povišenog CBC
A mildly elevated RBC count can usually be repeated after 1–2 weeks of recovery, ordinary hydration, and stable medication use when you have no red-flag symptoms. Repeat sooner only if your clinician requests it or the initial result was substantially elevated.
Before the repeat, record whether you had diarrhea, vomiting, fever, alcohol intake, a sauna, long travel, altitude exposure, fasting, or intense exercise in the prior 72 hours. Keep your usual diet and medication schedule unless your clinician tells you otherwise. This baseline blood-test preparation guide has a practical checklist for avoiding accidental variation.
Use the same laboratory when possible, because analyser methods and reference intervals differ. Ask for a CBC with hemoglobin, hematocrit, MCV, RDW, white-cell count, and platelets; persistent elevation accompanied by high platelets or white cells is more concerning for a marrow process than isolated erythrocytosis. A recent illness can affect these lines in opposite directions, so the full panel counts.
Кантести је услузи за тумачење лабораторијских тестова заснованој на AI-у that compares a new CBC with earlier values and flags changes that exceed ordinary variation. Our trend approach does not replace a clinician, but it can preserve the crucial context—exercise, illness, medications, and prior hematocrit—that is often lost when a single result is viewed alone.
Kada ponovljen visok rezultat zahteva testiranje na eritrocitozu
Persistently high hemoglobin above 16.5 g/dL in men or 16.0 g/dL in women, or hematocrit above 49% or 48%, should prompt a clinician to evaluate erythrocytosis after dehydration is excluded. The usual first tests are repeat CBC, erythropoietin level, oxygen assessment, and JAK2 mutation testing when appropriate.
Polycythemia vera is a myeloproliferative neoplasm in which JAK2 mutations are found in about 98% of affected patients. Low serum erythropoietin supports primary marrow overproduction, but no single blood test should be interpreted in isolation. The British Society for Haematology guideline recommends a structured approach that separates primary from secondary erythrocytosis (McMullin et al., 2019).
Symptoms can be subtle: headaches, blurred vision, itch after a warm shower, unusual facial flushing, fatigue, or a past clot may matter more than the exact RBC value. For a fuller explanation of hematocrit, erythropoietin, and JAK2, read our vodiču za simptome poliglobulije. Many people with mild laboratory elevation have none of these features.
I am careful not to imply that every persistent high count is cancer. Smoking-related carbon monoxide exposure, untreated sleep apnea, lung disease, testosterone, high altitude, and some kidney conditions are more common explanations in many practices. Still, persistence is precisely why a repeat CBC should not become an endless cycle of casual retesting.
Nizak nivo kiseonika, pušenje i apneja u snu kao uzroci visokog RBC
Chronic low oxygen can stimulate erythropoietin and cause a truly elevated red blood cell count; sleep apnea, smoking-related carbon monoxide exposure, and lung disease are frequent causes. A normal daytime oxygen saturation does not fully exclude overnight oxygen drops.
Obstructive sleep apnea can cause modest erythrocytosis, particularly when there are substantial overnight oxygen desaturations. Loud snoring, witnessed pauses, morning headaches, resistant hypertension, and daytime sleepiness should trigger a sleep-focused history rather than an assumption that dehydration explains everything. A vodič za analizu krvi kod kratkog daha outlines the broader cardiopulmonary context.
Cigarette smoking raises carboxyhemoglobin, which reduces oxygen delivery despite a pulse oximeter that may look reassuring. Vaping does not create the same carbon monoxide exposure as combustible tobacco, but it has other health risks and should still be discussed honestly. Carbon monoxide testing or co-oximetry is sometimes more useful than a routine oxygen saturation.
Kantesti AI interprets a high RBC result alongside hemoglobin, hematocrit, kidney markers, and reported sleep or smoking factors rather than presenting a generic cause list. That contextual reading is especially valuable when the hematocrit is 50% after hydration and the patient reports unrefreshing sleep.
Nadmorska visina, testosteron i lekovi koji povećavaju RBC
Living or training at altitude and using testosterone can increase red-cell production, so the elevation may be real rather than dehydration-related. The timing of exposure often answers more than the initial number.
At altitude, lower oxygen pressure stimulates erythropoietin and raises hemoglobin over days to weeks; the expected range depends on elevation, duration, ancestry, and laboratory reference data. A CBC collected during or shortly after a mountain stay should be interpreted against that exposure. Our altitude hemoglobin retest guide explains why return-to-sea-level timing matters.
Testosterone injections, gels, pellets, and some anabolic agents can cause erythrocytosis. Many prescribing protocols reduce or pause therapy when hematocrit reaches 54%, although individual risk decisions differ, especially in people with cardiovascular disease or sleep apnea. Never donate blood or alter a prescribed dose as a substitute for discussing the result with the prescriber.
Less commonly, SGLT2 diabetes medicines can cause a small rise in hematocrit, partly through plasma-volume effects and possibly erythropoietin signalling. A medication list should include over-the-counter androgen products, injectable treatments, and recent changes—not merely medicines printed in the electronic record.
Indikatori u CBC koji menjaju nivo zabrinutosti
High RBC is more concerning when hemoglobin and hematocrit are also high, especially with elevated platelets, white cells, low erythropoietin, or abnormal cells on a smear. A high RBC with low MCV often points instead toward small-cell disorders.
An MCV below 80 fL with a relatively high RBC count can occur in thalassemia trait, where cells are small but numerous. Iron deficiency can also lower MCV, although it more often lowers hemoglobin over time; ferritin and transferrin saturation clarify the distinction. Our Poređenje MCV i MCH explains why the RBC number alone misleads.
High white cells or platelets alongside a high hematocrit do not diagnose polycythemia vera, but they lower the threshold for a haematology review. A peripheral smear, ferritin, erythropoietin, JAK2 testing, and sometimes bone-marrow assessment may follow. Our put za testiranje na karcinome krvi shows why these tests are sequenced rather than ordered indiscriminately.
Dr. Thomas Klein’s practical rule is simple: look for agreement across independent signals. A hematocrit of 52%, platelets of 520 × 10⁹/L, and low erythropoietin is a fundamentally different pattern from hematocrit 50% after a heatwave with albumin 5.3 g/dL and concentrated urine.
Simptomi i rizik od ugrušaka: kada je visok RBC hitan slučaj
Seek urgent care for a high RBC result with chest pain, sudden shortness of breath, coughing blood, fainting, new weakness, speech difficulty, visual loss, or a painful swollen leg. These symptoms can reflect a clot or another acute condition and should never wait for a repeat CBC.
Higher hematocrit can increase blood viscosity, but symptoms and overall vascular risk determine urgency more reliably than a modest isolated elevation. Polycythemia vera carries a recognised thrombotic risk, particularly with older age, prior thrombosis, cardiovascular risk factors, and uncontrolled counts. Tefferi and Barbui's 2021 review describes risk-adapted treatment rather than treating every raised count in the same way.
Headache alone is common and nonspecific; headache with new visual symptoms, weakness, or confusion is not. Likewise, a warm shower itch can occur in polycythemia vera but also in dry skin and allergy, so it is a clue, not proof. Review blood-test warning signs for chest pain if symptoms are part of why the test was ordered.
Do not take aspirin solely because an RBC count is high unless your clinician recommends it. Aspirin has bleeding risks and may be inappropriate with ulcers, anticoagulants, low platelets, or certain medical histories. Emergency services are the safer choice when focal neurological or cardiopulmonary symptoms develop.
Zašto vaši prethodni CBC rezultati mogu odgovoriti na pitanje
A stable mildly high RBC count over years has a different meaning from a rapid rise over weeks, and trends can distinguish personal baseline from new disease. Compare results using hemoglobin, hematocrit, MCV, and the same laboratory whenever possible.
Biological variation and analyser variation mean a small change is not always a real physiological change. A 0.3 g/dL hemoglobin difference between two draws may reflect hydration, posture, timing, or ordinary variation; a sustained climb from 15.2 to 17.3 g/dL deserves more attention. Our article on značajnim laboratorijskim promenama explains the reference-change-value concept.
Keep a simple record of altitude, smoking status, testosterone dose, illness, heavy exercise, menstrual bleeding, and fluid losses at each draw. That record is more clinically useful than chasing one exact “ideal” RBC count. In my experience, the absence of this context is why patients receive conflicting explanations from different appointments.
Kantesti, a платформа за тумачење биомаркера помоћу AI, can display serial CBC values beside renal and protein markers to identify concentration patterns. We encourage users to treat trend analysis as preparation for a clinician conversation, not a replacement for an examination or targeted testing.
Razmatranja o trudnoći, starijem životnom dobu i hroničnim bolestima
Pregnancy usually lowers hemoglobin and hematocrit through plasma-volume expansion, so a high value in pregnancy deserves clinician review rather than a casual dehydration assumption. In older adults and people with heart or kidney disease, fluid advice must be individualised.
During pregnancy, plasma volume expands by roughly 40–50%, creating physiological dilution; many maternity services investigate hemoglobin above 16.0 g/dL because it may signal inadequate plasma expansion or other concerns. Severe vomiting in early pregnancy can still concentrate the CBC, but persistent elevation should be discussed with the maternity team. See laboratorijske crvene zastavice u trudnoći for same-day scenarios.
Older adults may not report thirst reliably, while heart failure and advanced kidney disease can make excess fluid dangerous. A rapid change in ankle swelling, weight, breathlessness, or urine output matters more than trying to meet a generic water target. Diuretic adjustments belong with the clinician managing the underlying condition.
Children have age-specific hemoglobin ranges, and a value that looks high on an adult portal may be appropriate at a particular age or altitude. A paediatric clinician should interpret persistent elevation, particularly with cyanosis, congenital heart disease, or poor growth.
Pitanja za vašeg lekara nakon visokog broja RBC
Ask whether your result represents hemoconcentration, whether hemoglobin and hematocrit are also high, and what repeat conditions are appropriate for your health history. Good questions prevent both premature alarm and missed persistent erythrocytosis.
Bring the complete report, not just the flagged RBC value, plus previous CBCs and a current medication list. Ask: “Were albumin, total protein, sodium, creatinine, BUN/urea, and urine concentration consistent with fluid loss?” This водичу за серумске протеине can help you understand why albumin belongs in that discussion.
If the elevation persists, ask whether oxygen assessment, sleep testing, erythropoietin, ferritin, JAK2 testing, or haematology referral fits your pattern. The answer will differ for a 28-year-old endurance athlete with hematocrit 50% and a 67-year-old smoker with hematocrit 55% and a prior clot. Specific history changes the work-up.
Kantesti’s clinical methodology is overseen with published quality standards and physician input; readers can review our приступ медицинској валидацији before using any automated interpretation. Dr. Thomas Klein’s bottom line is that hydration is a reasonable first check for a mild isolated result, but persistent high values deserve a real explanation.
Praktičan zaključak o dehidrataciji i visokom RBC
Dehydration can cause a false-looking high RBC result by concentrating blood, but it should be considered a working explanation only when the clinical context and companion laboratory markers agree. A normal repeat after recovery is reassuring; a persistent elevation should be investigated.
For an isolated, mild elevation after heat, gastrointestinal illness, fasting, or strenuous exercise, recover normally and repeat the CBC under consistent conditions in roughly 1–2 weeks. Avoid extreme water loading, and do not change diuretics, testosterone, or other prescribed medicine without advice. If you are unsure whether your result is only marginal, our резултат ван опсега водич explains laboratory flags.
For repeated hematocrit above 49% in men or 48% in women, or hemoglobin above 16.5 g/dL or 16.0 g/dL, ask for directed assessment rather than repeating indefinitely. Smoking exposure, sleep apnea, altitude, medication effects, erythropoietin, and JAK2 status are commonly considered in the next phase. Symptoms suggesting clotting or stroke need urgent care.
Кантести је Алат за анализу крвних тестова уз помоћ AI built to organise these results and their trends for an informed medical discussion. Our physician reviewers and Медицински саветодавни одбор emphasise the same principle: context first, repeat testing when safe, and prompt clinical review when the pattern persists.
Често постављана питања
Да ли дехидратација може да доведе до високог броја RBC?
Da. Dehidracija može izazvati povišen broj RBC jer gubitak vode iz plazme koncentriše crvena krvna zrnca u manjoj zapremini krvi, što se naziva relativna eritrocitoza. Hemoglobin i hematokrit obično rastu zajedno sa brojem RBC, a albumin, ukupni proteini, BUN/urea ili specifična težina urina takođe mogu biti povišeni. Blago izolovano povišenje često se normalizuje nakon oporavka i uobičajene hidratacije, ali trajni hematokrit iznad 49% kod muškaraca ili 48% kod žena zahteva kliničku procenu.
Koliko vode treba da popijem pre ponovnog testiranja visokog RBC?
Većina odraslih treba da pije uobičajenu količinu tečnosti prema žeđi 24–48 sati pre ponovljenog CBC, umesto da namerno pije prekomerne količine. Praktičan cilj je bledožuta mokraća i normalno mokrenje, a ne potpuno bistra mokraća ili forsirani unos vode. Osobe sa srčanom insuficijencijom, uznapredovalom bolešću bubrega, cirozom ili propisanim ograničenjem unosa tečnosti treba da zatraže individualni plan od svog kliničara. Brzo ispijanje nekoliko litara tečnosti može sniziti nivo natrijuma i dati nereprezentativan rezultat.
Koliko dugo nakon dehidracije treba da ponovim CBC?
Ponovljeni CBC se obično radi 1–2 nedelje nakon povlačenja povraćanja, dijareje, groznice, izloženosti toploti ili intenzivne fizičke aktivnosti. Kada je reč o promenama povezanim sa vežbanjem, izbegavajte neuobičajeno naporne treninge 24–48 sati pre uzimanja uzorka i održavajte normalan unos tečnosti. Vreme može biti i kraće ukoliko je hematokrit izrazito visok, ukoliko postoje simptomi ili ako su bubrežni parametri abnormalni. Gde je moguće, koristite istu laboratoriju kako bi referentne vrednosti i metode analizatora bile uporedive.
Koji se broj RBC smatra opasno visokim?
Ne postoji jedinstven broj RBC koji definiše opasnost jer rizik više zavisi od hematokrita, hemoglobina, simptoma, uzroka i istorije nastanka tromba. Hematokrit od oko 54% ili viši generalno zahteva hitnu kliničku procenu istog dana, dok uporne vrednosti iznad 49% kod muškaraca ili 48% kod žena opravdavaju ispitivanje eritrocitoze. Bol u grudima, iznenadni nedostatak daha, gubitak vida, slabost, poteškoće u govoru ili bolna otečena noga su hitna stanja bez obzira na tačan broj. Ovi simptomi zahtevaju hitnu procenu umesto čekanja na hidrataciju ili ponovno testiranje.
Mogu li diuretici da uzrokuju povišen broj crvenih krvnih zrnaca?
Diuretici mogu uzrokovati povišenu koncentraciju crvenih krvnih zrnaca smanjenjem volumena plazme, naročito nakon povećanja doze, po toplom vremenu, usled nedovoljnog unosa tečnosti, povraćanja ili dijareje. Oni obično ne podstiču koštanu srž da proizvodi dodatna crvena krvna zrnca, tako da se ovaj efekat može povući kada se balans tečnosti uspostavi. Nemojte samoinicijativno prestajati sa uzimanjem furosemida, hidrohlortiazida ili drugog propisanog diuretika jer ovi lekovi mogu kontrolisati srčanu insuficijenciju, krvni pritisak ili otoke. Razmotrite CBC zajedno sa telesnom težinom, krvnim pritiskom, kreatininom, natrijumom, kalijumom i simptomima.
Da li visok RBC uvek znači policitemiju veru?
Ne. Većina visokih rezultata RBC automatski ne znači policitemiju veru; dehidracija, ugljen-monoksid povezan sa pušenjem, apneja u snu, nadmorska visina, bolesti pluća i testosteron su česti alternativni uzroci. Policitemija vera postaje verovatnija kada hemoglobin ostaje iznad 16,5 g/dL kod muškaraca ili 16,0 g/dL kod žena, hematokrit ostaje iznad 49% ili 48%, eritropoetin je nizak, a JAK2 test je pozitivan. Policitemija vera ima JAK2 mutaciju u oko 97% slučajeva. Kliničar treba da tumači ove testove kao obrazac, a ne da postavlja dijagnozu na osnovu jednog CBC upozorenja.
