Hematocrit (Overview)

Of red blood cell number. Classically this was the "packed cell volume." blood was placed in a microtube and spun in a centrifuge. The rbcs settle to the bottom and one measures the height in the tube and reported as a percentage. Now determined by an automated machine. A typical hct is about 3 x the hemoglobin (hgb).

What's hematocrit in the blood?

What's hematocrit in the blood?

It's a percentage: Basically, the hematocrit is a volume percentage of red cells in whole blood (the other parts being primarily plasma, white cells and platelets). Low or high hematocrits could indicate disease processes; however abnormal levels are not uniformly something to worry about. ...Read more

Cbc test shows high wbc, low hematocrit, low mcv, low mch, high platelet count, low lymphocytes and monocytes - can you define these for me?

Cbc test shows high wbc, low hematocrit, low mcv, low mch, high platelet count, low lymphocytes and monocytes - can you define these for me?

Hard to say...: It sounds like it may be an infection but it's impossible to say without more information including if you have any other signs or symptoms. It is also important to know the numbers: how high is that wbc, for example. The best way to go for you is to discuss it with you doctor directly. ...Read more

If I was prescribed Diovan (valsartan) hct, can I subsitute it with hydralazine HCl for cost purposes?

Yes and no: They are both blood pressure medicines, but they work very differently.

Because they work differently, they have different scenarios we use them in. ...Read more

How low your hemoglobin hematocrit to do work up for anemia?

Find cause: I would investigate any anemia in the hope of finding a treatable cause, especially before things get serious. Iron deficiency causes fatigue before it causes anemia. ...Read more

16wks pregnant and hemoglobin is 10.8, hematocrit 32.7. My dr. Prescribed iron supplement ferrous sulfate 325mg (65 fe) to take 2x a day. Is this safe?

16wks pregnant and hemoglobin is 10.8, hematocrit 32.7. My dr. Prescribed iron supplement ferrous sulfate 325mg (65 fe) to take 2x a day. Is this safe?

Yes.: When you are pregnant you need to expand your blood volume, and to make more red cells you need iron. It is absolutely safe, although some people have stomach side effects like constipation or nausea. Slow release versions of iron may be better tolerated in that regard. Iron preparations are available without prescription. ...Read more

How dangerous is a hematocrit of 24?

Depends: It is something that should definitely be evaluated. Either you body isn't making enough red blood cells or you are losing them somewhere. The hematocrit of 24 is not a danger on its own. Your body can tolerate a crit that low. You need to be evaluated for the cause, though. ...Read more

Elevated hemoglobin 18.3, elevated hematocrit 54.8, elevated bilirubin 1.9. Abdominal pain Adult age 43. Why?

See hematologist: Possible causes include cigarette smoking or other source of carbon monoxide poisoning, chronic lung disease, sleep apnea, kidney tumor, and polycythemia (a marrow disease). See a hematologist. ...Read more

At 4wks pregnant, WBC 14.3, RBC 3.40, hgb 10.7, hct 31.7. Will anemia this early in pregnancy hurt baby or increase chance of miscarriage?

At 4wks pregnant, WBC 14.3, RBC 3.40, hgb 10.7, hct 31.7. Will anemia this early in pregnancy hurt baby or increase chance of miscarriage?

No: It's common, very common, for women to have some anemia such as you have. If you take an iron pill with citric acid (orange juice to increase absorption) you should be fine. You can also try to increase iron by eating iron rich foods. It's always better if you can, to eat iron rich foods than take supplement. But will not increase risk for miscarriage or hurt baby unless hgb. ...Read more

Test results! Bun=6 /hematocrit=34/hct ic =35.1. Is these normal results? The paper I was given shows these are below normal but dr said they were ok

What's "normal"?: Reference ranges are set so that several percent of healthy folks fall outside on either end. "normal" doesn't necessarily mean "healthy" in any case. Especially, low BUN in a person who looks and feels well never means anything. Your physician gave you good advice. ...Read more

What do blood results mean? TIBC, Hemoglobin, Hematocrit, RBC & MCH all LOW. Retic count & RDW are HIGH. Iron, Tran Sat, Ferriten, MCV NORMAL

Anemia: Your results indicate anemia. The cause requires identification. Strong possibilities from high retic count include blood cell hemolysis (breakdown) or blood loss from your body. Needs more attention as soon as possible. ...Read more

Low hemoglobine, hematocrit&creatinine w/anisocytosis poikilocytosis anisochromia microcytes dianocytes schitocytes difusse basophilia, what it means?

Get it looked at: Your peripheral smear and your labs need to be reviewed by a hematologist or hematopathologist for accuracy of the lab report and possible diagnosis. It may be nothing more than minor genetic fluke, or something significant. Heads up -- vasculitis in the gall bladder wall is usually nothing to worry about though it scares some pathologists into overcalls. ...Read more

What does it mean if CBC consistently shows low RBC but normal hematocrit and hemoglobin?

What does it mean if CBC consistently shows low RBC but normal hematocrit and hemoglobin?

Not much: If blood contains normal amount of hemoglobin, it will carry oxygen to tissues and CO2 to lungs normally. If red cells are a little larger than normal, number of red cells ("RBC") could be slightly low. You could have macrocytosis (large cells) without disease, but might want MD to rule out some causes of it (low B12, low thyroid, increased reticulocytes, and others) just to be sure. ...Read more

Could you tell me what are leads to for high hematocrits?

Polycythemia: Elevation of hemoglobin / hematocrits is called polycythemia. It can be divided in to two groups- primary bone marrow problem- is called- polycythemia vera vs. Secondary polycythemia that can be caused by / associated to different conditions- including dehydration, significant lung disease, problem with liver, cysts, familial conditions etc. D/w your md and you may need to see a hematologist. ...Read more

How can I treat a low hematocrit?

Depend of the cause: Treatment for anemia (low hemoglobin/hematocrit) has to be directed to the underlying cause/etiology of the anemia. Many things can cause anemia eg- bleeding, iron deficiency, deficiency in other nutrient, red blood cells destruction, drug induced, bone marrow failure, other red blood cells disorder etc. See you doctor and have further evaluation. If complicated- see a hematologist to help you. ...Read more
