49 yr old Male is a Full Blood count a
Mean Corpuscular Volume (MCV) of:
91.2fL ( Range 80.00-100.00fL) Normal in B12 Result in UK?
I have been told my mean corpuscular volume is high. I have moderated my alcohol intake and begun taking a multi-vitamin. What can it cause?
Vitamin deficiency: Large (macrocytic) red blood cells usually result from a deficiency of vitamin B12 or Folic Acid (folate). If you are taking those and your macrocytes don't improve, you may not be able to absorb the vitamins from you GI tract. You may wish to see your doctor again or consult a hematologist if things don't improve. ...Read more
I had a CBC last week doc said its normal. Wbc 7.3 RBC 5.7 platlets 318 pcked cell volume 48% MCV 83fl neut. 36% lym. 56% eos. 04% mono. 04% baso. 00%?
Sounds normal: Sounds like a normal cbc. Wbc of 7.3 is in normal range, neither too high nor too low. The neut, lym., eos., mono., and baso are the 5 types of wbc's and the numbers indicate the percentage of each of the 7.3 (actually 7300) . The percentages show a normal distribution. Platelets help your blood to clot, and the number is normal. Finally are the rbc's, and the numbers for them are normal. ...Read more
Many things: I wouldn't worry so much about the high B12 level, as that isn't so much a cause of the a high MCV, in fact the opposite is true(low B12 levels cause high MCV). But a high MCV, means your red blood cells are large. This can be related to many things, from a higher number of immature red blood cells, underactive thyroid, too much alcohol, liver disease, low folic acid just to name a few. ...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. follows MCV ...Read more
Polycythemia.: High HGB levels for 3 kinds of reasons. First, a blood disease where too much blood is made. Second, the blood is being made due to an increase in epo, the hormone that controls production. Can be from lack of oxygen (lung disease, living at high altitude, abnormal hemoglobin, carbon monoxide/smoking poisoning hemoglobin, heart disease, or rarely tumors. Dehydration can do this too. ...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
