I recently noticed while looking back at some pre-TRT labs that the Free T results and reference ranges between Quest and LabCorp differed significantly. With the help of this forum, I learned that those values can't be compared.
Can the same be said for Total T readings? For example, I have these two different pre-TRT results:
LabCorp: Total T 378 (range 248-1197)
Quest: Total T 333 (range 250-1100)
