[QUOTE="LiftOn, post: 47462, member: 2546"] I would make sure your test is LC/MS instead of ECLIA (immunoassay). I had one with the cheaper tests (immunoassay) and it had my number over 1000. LC/MS had it in the 700s (about 4 weeks apart). Pulled from another post on here (note the last part): [B][COLOR=#a30706]Frequently Asked Questions: Testosterone by ... - LabCorp[/COLOR] (link wouldn't go out b/c I don't have enough posts) [B]Types of blood tests for testosterone There are two types of blood tests frequently used in gauging your testosterone production and retention levels: the LC/MS method and the ECLIA method.[/B][/B][B]LC/MS LC/MS, or liquid chromatography-mass spectrometry, is the Mercedes-Benz of blood testing for testosterone. The CDC classifies LC/MS testing as the most reliable method for testing your total testosterone level. (Quest Diagnostics) LC/MS is also extremely sensitive, which makes it the preferred method for testing patients with chronically low testosterone levels. ECLIA ECLIA is the more widely-used blood test by clinics to gauge your total testosterone. ECLIA (Electrochemiluminescent Immunoassay) is quick and far more affordable that LC/MS. [U]Unfortunately, ECLIA also tends to register testosterone levels as being higher than they truly are.[/U][/B] [/QUOTE]
