What could cause low MCV and high RDW but normal MCH, hemoglobin, and hematocrit for over a year?

What could cause low MCV and high RDW but normal MCH, hemoglobin, and hematocrit for over a year?

How low?: Reference ranges are set so that several percent of healthy folks fall outside on either end. If your peripheral smear is unremarkable and the MCV above 70, I'd forget the whole thing. My RDW is always high from donating blood. There are some variants of thalassemia minor that will produce this and puzzle people over a lifetime, though MCH is usually lowish. ...Read more

Hematocrit (Definition)

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 ...Read more

Blood test result show high packed cell volume ,high RBC, high WBC and high Neutrophil count what does it mean ? With Hand Burning and oral thrush.

Blood test result show high packed cell volume ,high RBC,  high WBC and high Neutrophil count what does it mean ? With Hand Burning and oral thrush.

By itself, nothing: You're a young man and your somewhat high Hct may simply be you -- reference ranges are set so that several percent of folks fall outside on either end. Same for white count. The oral thrush, if proven, calls for a check for a few illnesses; the hands, a neuropathy workup perhaps. Labs are meaningful only in the context of clinical fnidings. Your physician owes you a full explanation. ...Read more

My dads CBC range: RBC 3.95,haemoglobin 11.9, packed cell volume 34.9.others are all in range.he is 54yrs.is this a serious concern.what should he do!

My dads CBC range: RBC 3.95,haemoglobin 11.9, packed cell volume 34.9.others are all in range.he is 54yrs.is this a serious concern.what should he do!

Fecal occult blood: For an otherwise healthy man hemoglobin of 11.9 is lower than expected and occult blood loss needs to be excluded. It would be prudent to exclude blood loss in the GI tract. His doctor may start with testing for blood in the stool and go from there. The finding should not be ignored. ...Read more

Inflammation: You are anemic and have inflammation. Check 25-oh vit d level. Anemia could be due to iron deficiency if having heavy periods. That can make you more toxic to cadmium a pollutant that is activated by stress and increases cr-protein. Improve health with healthy food, supplements to prevent deficiency, a good night sleep, mild exercise through the day, and de-stress. See kelly mcgonigal's book. ...Read more

Labs, hematocrit high 46.9, MCHC low at 31.9 and red blood cell high at 5.16. Had labs done myself. What could cause this. Anxious something's wrong!

Labs, hematocrit high 46.9, MCHC low at 31.9 and red blood cell high at 5.16. Had labs done myself. What could cause this. Anxious something's wrong!

Try HealthTap PRIME: Lab results usually are numbers, and numbers are just numbers, with little meaning unless a doctor takes in the whole picture of what's going on with his patient. "Creating patient anxiety" is one of the arguments against people doing their own lab tests. One can try HealthTap PRIME for a virtual consultation, in which a doctor can ask questions and look over the lab results, to explain them. ...Read more

Recent blood test shows low indirect bilirubin (.08)+increased blood volume (99.7)+increased hematocrit (47.2)+high WBC (14,200). Huh?

Recent blood test shows low indirect bilirubin (.08)+increased blood volume (99.7)+increased hematocrit (47.2)+high WBC (14,200). Huh?

Uncertain.: The WBC is definitely high, but the HCT and MCV are borderline, and thus of uncertain significance. If truly elevated, the HCT could point to a primary or secondary polycythemia, an increase in the number of red blood cells. But this could also reflect mild dehydration, and given the borderline degree could be nothing. The high WBC is real. If you have no symptoms I would just repeat in 1mo. ...Read more

What can happen with untreated high hematocrit, red blood cell counts, and blood calcium levels? I do live at high altitude in SLC, Utah.

What can happen with untreated high hematocrit, red blood cell counts, and blood calcium levels? I do live at high altitude in SLC, Utah.

Nothing for high HCT: Your hematocrit is high due to living on high altititude which may be normal physiological reaction to O2 level being low.But we do not know how high it is to comment High Calcium level needs to be further investigated as it may be due Primary Hyperparathyroidism or Secondary Hyperparathyroidism You need to have blood level of Calcium,Parathyroid Hormone Level,25 Hydroxy VitD level as well Consult ...Read more

Hemoglobin hematocrit and red blood cell low counts and glucose and nitrogen high what is cause 
?

Numbers are numbers: Lab results are numbers, and numbers are just numbers. They have little meaning without looking at the whole person. Low hemoglobin, hematocrit, and red blood cell counts means blood cells are not being made fast enough, are being lost (through bleeding), are being broken up, or any combination of such problems. Glucose goes up from increased body stress, inadequate insulin, I.V. Glucose, etc.... ...Read more

Last blood test:high red blood cells( 5.8) high hemoglobin (17.3) high hematocrit 52% and high bilirubin 2.1. What's wrong with me? Polycythemia vera?

Hey buddy!: You've asked this question repeatedly. Being a smart teen with an interest in science, you're understandably concerned. At your age, and with normal cbc's as a kid (were they normal?) i'd be more concerned about sleep apnea -- that will ruin your life -- or that someone is giving you Anabolic steroids without your knowing it, or an erythropoietin-producing tumor somewhere. ...Read more

What causes Low Immature Granulocyte, High Neutrophil. High Hematocrit, High White Blood Cell Count?  Have bone pain but rf factor shows normal.

See below: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, it would have helped to have the actual results. Why were the tests done? What symptoms do you have? It would require taking history, physical examination and may be more tests to settle the issue. Please see your doc. ...Read more

What's your question: A blood test isn't a patient; you are. You didn't just wander into a phlebotomy office and make an impulse purchase. A doctor ordered the CBC for a reason. What was the reason? Also, please repost with the discussion you had with your doctor about the significance of these results; or if you have not asked your doctor, please state why not. ...Read more

Red blood cells-5.9, hematocrit- 55%, hemaglobin-18.0, esr-2, ldh-199, white blood cells- 9.0 (high neutrophils) & platlets-285, 000 polycythemia vera?

Can't tell. need w/u: Normal range will vary -depending on the range used on each lab. On my lab, hb of 18 is still normal for male. Your white blood cell and platelet are also within normal range. I don't see any problem there-except you said you have high neutrophils- which can be caused by many things. However, if you are worried about p.Vera- go to see a hematologist and she/he will be able to help you. ...Read more

Why might having a sickle cell anemia crisis result in a reduced red blood cell count, an elevated white blood cell count, and a reduced hematocrit?

Why might having a sickle cell anemia crisis result in a reduced red blood cell count, an elevated white blood cell count, and a reduced hematocrit?

Acute blood trapping: Sickle cell crisis occurs because these patients red cell are not elastic, gets trapped in vessels, in spleen,liver, lungs,leading to loss from circulation, hence low red cells and hematocrit in CBC. Repeated episodes compromise immune functions and patients prone to infections, which could then induce rise in white blood cells to fight infections. BE hydrated, No strenous exercise ArePreventive. ...Read more
