First off you can’t test for hormones on the spot, they need to sent to the labs and specifically test for each compound. This is very expensive. Now guys on parole, probation, or drug court the PO’s will randomly do this. No panel test can provide results on the spot. Now one thing I can tell you this happened to me was I was taking clenbuterol and it gave a positive result for amphetamine on a panel test. Then at that point my sample was sent in to check it individually for amphetamine alkoids and came back negative. Anyways certain supps , AAS, vitamins can give a false positive.
