[QUOTE="tareload, post: 220074"] For the interested reader, note the units on the ordinate (y-axis) of both graphs above. This is where folks get really confused between (1) correlation vs (2) parity (as compared to ED or UF measurement). direct RIA fT measurement does not yield a physically realistic estimate of fT. Multiply the direct RIA fT measurement [convert typical pg/mL to ng/dL] by 7 to get ballpark actual fT number [ng/dL]. Hence, taking the direct RIA fT at face value would cause one to drastically underestimate their %fT (and also really mess up any estimate of SHBG from fT+TT using online calculator).
