I had a guy come in last week with a complaint of "low T". I pulled the lab queue and ordered "testosterone, free, male", along with a thyroid panel. While in there I ordered my own as well. He had the work done and I got his results back today. The reference ranges were 8.2-25.7.
This is a different range of numbers than what I have seen on Lab work from posts. Is it just that labcorp publishes their results in a different format, or is there a more specific test that I could've ordered. There were probably 10 different testosterone tests available, I just figured "free, male" was likely the right one. His came back at 10.2, so I wrote him a referral to endo. Interested to see what my numbers are. Any thoughts?
