How was test run?: There are several ways to test/check Testosterone (eg RIA, ECLIA, LC/MS/MS). While the results are sometimes similar, often they differ dramatically. Check Table 3 if blood drawn at Quest: http://www.questdiagnostics.com/testcenter/testguide.action?dc=TS_Testosterone_LCMSMS. Despite using "same" method, LabCorp gives different normal reference range http://goo.gl/njp7Nm.
