Privatemdlabs, Can't find correct test

Trying to get my 3a-Androstanediol Glucuronide tested as I’ve started to experience some PFS effects. I’ve been on 1mg finasteride/day for about 5 years. I ran out for about 3 weeks so had to stop for that time. I’m looking on privatemdlabs trying to find the correct test. I can’t seem to find the one that tests for 3a-Androstanediol Glucuronide. Any help?
