OK, thanks for the correction...what was it that 'they' tried to get out of
the doctors or family members that created a minor fuss a while ago?

EPO is a naturally occurring hormone in the body, but at a certain range.
In normal patients, serum levels of erythropoietin range from 15-19 miu/ml
and can increase 100 to 1000 fold during hypoxia or anemia. So it's no good
testing for 'EPO level'. The detection has to be on unusual products of
exogenous substance, or changes in a ratio (like the T/E ratio for
testosterone), or in subtle differences in the cloned or recombinant versus
the natural human hormone. Often there are no differences, which is the
current case, afaik for hGH.
