I have a slightly result above normal range of MCV. What does this indicate?

I will be 72 in October, am 152 pounds and 5' 8" tall. Was 152 when I graduated from college in 1962. Do not smoke and do not drink (except for an occassional glass of wine . At most 1 a month)

Am in good health. Had a melonoma 7/2011 but it was a surface one and was successfully removed with no trace in the after biopsy.

My latest MCV was 101 (8/7/12). The one before that was 103 (9/15/11)

I had the same doctor for 20 years and changed for the 9/15/11 tests. (Prior doctor was in NYC, NYU Medical Center. 68 years of age. He was a specialist and treated me for high blood pressure and high cholestrol. Both controlled by lipitor .5 MG / day and rampril 10 mg /2 x day, with atenetol 25 mg / 2 x per day. Have taken the lipitor for 8 years and the other 2 for 20 years.It was an all day journey to visit him as I live in NJ 50 miles away.)

The new doctor (DO) is local and a 10 minute trip. She is in her late 30's or early 40's. She started me on folic acid 1 mg /day 9/15/11.

I also take saw palametto 450 mg and fish pill 1000 mg / day for my prostrate which is enlarged but ok. Regularly see a urogolist . Had bladder stones removed 5/2010 with green light lasar surgery on the prostrate. No problems now.

My latest MCV was 101 (8/7/12). The one before that was 103 (9/15/11)
I have my reults going back 10 years. The past 5 years were between 99.9 and 99.2. The prior 5 years were between 96.6 and 97.7.

The MCV is just over the normal range. Is this an issue? What is the overall + or - on the tests. What is a real alarming result on the MCV test?

Thank you
