T Testing

Does anybody know if the total testosterone test picks up just testosterone, or does it also pick up any circulating esters of test?

There may be minor a cross testing result. But this would have been addressed a long time ago. Also note that the life of T esters in the blood before the ester group is removed is quite short.

So serum T ester levels are going to be low. Tests differentiate between the 3 estrogens, testosterone, DHT, pregnenolone, progesterone, DHEA etc. I think that this concern can be put out of mind.
