The fT assay used here is a “direct” immunoassay and way off (note the units and then what is the calculated %fT?). Using Vermeulen calculator:
Vermeulen calculated estimate typically 10-20% high compared to current gold standard equilibrium dialysis method. So let’s say 0.8*14.7 = 11.8 ng/dl
Your original fT is in a good range for healthy fT levels (10-20 ng/dl).
Tread carefully.
More info (very good thread to learn about units and details of fT before you put yourself on testosterone…pay attention to units):
You are self-medicating based on a practically useless free testosterone assay (windsock).
