Question: RBC is high but MCH, MCV and MCHC are low

 patient07 - Thu Apr 12, 2007 8:14 pm

Pls help as I am really worried about my health status, though I am feeling well and perfectly fine. Kindly interpret the results after our annual medical exam at the office.

Hemoglobin 13. 9 (13-18)
Hematocrit 49. 2 (40-52)
RBC 6. 65 (4. 7-5. 4)
MCV 74 (80-100)
MCH 21 (28-33)
MCHC 28 (32-38)

WBC 8710 (4800-10800)
Lymphocytes 4050 (1500-4000)
Monocytes 1071 (200-800)

I was healthy and fine when I had my test done. However, my RBC is high but MCH, MCV and MCHC are low. Is that possible?Ive been taking multivitamins since college that includes iron, shall I increase my Iron intake?. Can you kindly enlighten me as well for my WBC?

By the way, I also had the same results when we had the test last year. My RBC was high and MCH, MCV and MCHC were low. I was also healthy and fine when I had my test done. Pls tell me im fine and healthy cus im really so worried as I havent been sick since.

Thank you in advance.

User avatar Basically all your labs are normal.

The elevated RBC count is not significantly high. Your low MCV, MCH and MCHC support iron deficiency. If you have been taking a multivitiamin with iron it may be that you are not absorbing it well.

Before increasing your iron intake too much I would recommend you talk with your doctor aboutt having some tests done to directly measure your iron levels (iron level and total iron binding capacity). There are a few other causes of a low MCV that will not be corrected by iron.

Your WBC count is normal. The increased amounts of lymphocytes and monocytes likely indicates that you had recently been exposed to a virus and your body was fighting it off. This is nothing to be concerned about as they are only slightly elevated.

Best wishes.

Thanks so much doctor! Nice to know there are people around here willing to listen and clear doubts of anxious and very worried people like me. I will just continue to take my multivitamins and i will try to hit the gym as often as i could.

God Bless and More Power!
