Hello,

One has to evaluate labs based on the lab normals. Furthermore, the distribution of the numbers is important. The MPV varies with age and gender and the labs never actually mention the age issue.

A large change would mean more even if all values are in the normal range. 11.0 doesn't SEEM all that abnormal. and it doesn't have much to do with thyroid, so, with an adjustment of thyroid which usually goes DOWN with age, getting a repeated value after being on it a while would be the usual practice.

Hope I have answered your query. Let me know if I can assist you further.

Take care
