What Does Mcv
MCV = Mean corpuscular volume. A measure of red cells size.
MCHC = Mean corpuscular hemoglboin. Amount of hemoglobin in an average red blood cell.
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. Talk to the doctor who ordered the tests.
Wish you good health! - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex. ...Read more
Red cell indices:
MCV is mean cell (corpuscle) volume
it is the average size of the red cells
it is used to study and classify anemias (low hemoglobin states)
low MCV = microcytosis= iron deficiency or thalassemia
normal MCV= normocytic= anemia of inflammation or malignancy =80-100
high MCV= macrocytosis= B12 or folate (folic acid) deficiency and others
MCH = mean corpuscle or cell hemoglobin. Used less.

What does low MCV 74 low MCH 23.7 high RDW 16.6 mean? Everything else normal. CMP, LDH, CBC- freaking out! Can this be Vitamin Deficiency?
Iron deficiency: 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, what you provided suggests iron deficiency. Consult the doctor who ordered the tests. You may take oral iron and multivitamin supplements. ...Read more
Mcv: The mcv- is mean cell volume, is the average volume of red cells, part of a complete blood count. Mcv is calculated from the hematocrit and red cell count (mcv= hct x 1000 / rbc (in millions per microliter). In anemia, MCV allows classification as a microcytic anemia (mcv below normal), normocytic anemia (mcv in normal range) or macrocytic anemia (mcv above normal. ...Read more
Big picture: Small red cells with too little hemoglobin usually mean iron deficiency which should prompt a search for bleeding. There are some other possible causes. ...Read more
What does having low MCV high red blood cells with abnormal morphology with low neutrophils and high lymphocytes counts mean?
Thalassemia?: Low MCV (small sized) red cells with increased number of rbcs is most commonly seen with thalassemia, an inherited hemoglobin abnormality, but it is not associated with low neutrophils. Not all low neutrophil counts are significant, as normal varies with ethnic background. Infections can cause temporary low neutrophils. See a hematologist to sort this out. ...Read more
All results: 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 been helpful to have all the results and actual values of the results. One possibility is deficiency of iron and folic acid and/or B12. ...Read more
Need more info: It may be a combination of circumstances, and it would be helpful to know the actual values. Given the information your provided, it may be a combination of macrocytic change and dehydration. Alcohol use could be one explanation. 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. ...Read more
Spurious vs real:
Need good history. Decrease plasma volume or stress erythrocytosis would be spurious.
Secondary causes could include anything associated with tissue hypoxia ex. Chronic pulmonary disease. Normal arterial po2 could mean increase carboxyhemoglobinemia 2nd to cigarette smoking. Inappropriate increase ex renal disorders;ex renal cyst or ca.
Primary cause; p. Vera bone marrow disorder.
Few examples. ...Read more
My vitamin D 25 Hydroxy test came out value 22. I live in Michigan so not much sun. What does this mean? My mcv is 80.3 are these of concern?
Maybe supplement: You might feel some better if you supplement the vitamin D or start eating something that's rich in the stuff. The MCV is fine, same as mine, ...Read more
Why do you ask?: A very low mcv with other labs basically normal is usually Thal minor, a mild genetic variant that you simply need to understand. Low mcv can also warn of iron deficiency or a few other serious problems. Lab values aren't things to treat. Find the reason. ...Read more
Mean Corpuscular Vol: MCV refers to average size of red blood cells. Just like Goldilocks, you want everything just right, not too big, not too small. High MCV suggests possible vitamin B12 and/or Folate (folic acid) deficiency. You didn't ask, but low MCV suggests possible iron deficiency. What if you're deficient in all 3? Then MCV will be normal but RDW (red cell distribution width - it's a statistical thing) will be high. ...Read more
Find out why: If you're mildly or not anemic and your RBC count is a bit high, you probably have thalassemia minor which is a non-problem unless you marry someone else who has it. If your RBC count is also lowish and/or you're seriously anemic, you're likely to be iron deficient. There are other possibilities. Your physician needs to explain. Best wishes. ...Read more
That is significant: Could be severe iron deficiency. Also could be thallessemia. If you are anemic you should see a blood specialist ...Read more
I have a slightly low MCV value of 78 fl. Is there any need for concern, and how can I raise this to more normal levels? Thank you.
Need more info:
Iron deficiency and thalassemia trait are common causes of low MCV. If your hemoglobin is normal. There is no need to be concerned about an MCV of 78.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.

A little high: But you have to interpret this value with others. It may be your 1 year old (also a slight difference for boys and girls) has an anemia. You should discuss with your pediatrician as s/he will have the other important lab results as well. S/he may want to check folate (folic acid) levels or other tests if not already done. Most likely at this age it's related to your child's diet. Please discuss with her/him. ...Read more
Yes: These indicate that red blood cells are much larger than normal. There are several reasons this may occur. Diseases such as pernicious anemia, hemolytic anemia, liver problems, alcoholism, folate (folic acid) deficiency, and myelodysplasia are some. Certain medications can also lead to this. Please consult with your health care provider. ...Read more
Why do you ask?: Forgive my frankness. If your MCV is over 100 fL or so, you need a scientific workup rather than a focus on "environmental medicine". I'm going to assume you're not a heavy drinker. B12 and folate (folic acid) deficiency, and thyroid hormone deficiency, are all real and present threats to your health. You may simply have a cold agglutinin or mild hemolysis. But don't focus on "pop" ideas. Demand the truth. ...Read more
How's iron level?: The MCV is lowish, about where mine usually runs, but not inconsistent with good health. RDW tends to rise in early iron deficiency, before anemia appears, but this is by no means the only possibility. If you may be iron deficient (vegetarianism, heavy periods, pregnancy), your physician may check iron and iron binding capacity & discuss possible supplementation. Glad you asked, best wishes. ...Read more
How do you FEEL?: Your physician might look at the peripheral smear. Is anything else off? Are you actually sick? What is your reticulocyte count? An athlete can raise this quite high just from pavement-pounding. There may be a cold agglutinin. You may just want to repeat the tests. Do you drink alcohol? Was your thyroid checked? (Famous cause of high MCV often now recognized.) Best wishes. ...Read more
