New to the site but I have read a million post in the last two weeks. Thank you for all the information! I will save the entire back story, just wondering what test I took this morning. It was at a Concentra facility and I am pretty sure they send it out to Quest Diagnostics. The code on the test paperwork is: 27215N SAP 5-50/2K+MDMA5/TS I THINK I understand most of it, but the TS is throwing me off. Any information would be great. Thanks!
