Bioavailable vs Free Testosterone

Quest labs provided me with both a Free and Bioavailable testosterone level. All my last labs just provide Free not bio. I have seen these terms bio and free used interchangeably a lot but they are obviously different. What’s the main difference? and which is more meaningful for TRT purposes ?
 
Checking Free T using the equilibrium dialysis is the best method. I consistently see the bio T well above what Free T is showing. All methods have their problems.
