I would have to have a doctor willing to order it. What is FT? LabCorp did this test. But my doctor ordered it.You had your FT tested using the direct immunoassay (post #12) which is known to be inaccurate.
You need to have your FT tested using an accurate assay (ED or UF) especially in cases of ALTERED SHBG.
Seeing as you reside in the US you have access to the most accurate assays for FT through Labcorp or Quest Diagnostics.
Otherwise for the time being you will need to use/rely upon the cFTV.
