RE: [RC] [RC] [RC] selenium level - heidi



I've heard that a serum selenium level is not

accurate.  That selenium is stored in adipose
tissue and the only way to get an accurate result
is to do a punch tissue biopsy.


I'd agree that a serum selenium is not accurate, but what is generally
run is a whole blood selenium.  Because of the incorporation of
selenium in cell membranes, this is apparently quite accurate.

I've never heard of having to do a tissue biopsy for selenium--not that
it isn't done, but it certainly isn't a standard test.
