[QUOTE="DragonBits, post: 145052, member: 18023"] I get totally confused by all the different unit measurements used. If it was simply a matter of different units, then one should be able to convert those units. But it seems that it's more complicated than just a unit conversion difference. For Total T of 690 ng/dl, SHBG of 41.1 nmol/L and Albumin 4.6 g/dL Labcorp gave me the following Free T result. Free Testosterone(Direct) 20.7 High pg/mL. =================================== Converting pg/ml > ng/dl should be moving the decimal point over one to give 2.07 ng/dl. But a 2.07 ng/dl doesn't make any sense and doesn't jive with any online calculator that would say my free T was 13 ng/dl. Obviously something is wrong with my math, but I don't know what. BTW, TruT would say my free T with the same numbers is 21.51 ng/dl, but who knows what the range should be? I can certainly see why most doctors only look at total T and SHBG and tend to ignore freeT. How does one convert Labcorps Free Testosterone(Direct) 20.7 pg/mL to ng/dl units and to nMol/L units? It should be possible to convert if it is only a unit difference. [/QUOTE]
