hello,

I thought the normal range for reticulocytes was in the region of 26 - 130, according to wikipedia and other references i've seen online.

But when i had my latest blood test returned last week, the reference range written on the printout was 50 - 100.

Does anyone have any information on this discrepancy/why the range has been narrowed?

my count last month was 20, this time its gone up to 30. Everything else ok, except for my eosinophils which are now playing up - stable for the last seven years at 0.1. Last month they had gone up to 0.4 (top of the normal range). This month they've leapt up again to 0.8. I know that none of this is like majorly serious compared to how low these counts can go, but still it makes me a bit uneasy...

cheers, jane

PS. Can anyone give me a link to a table that compares the way blood is measured in units. There seem to be a vast array of different ways of measuring.

pps. Can anyone point me to information about how normal ranges/reference ranges are calculated.
