This is definitely not common, only parents who are super responsible, would do something such as this, considering the generational decline and testosterone.

I would only use the equilibrium dialysis method for the Free T measurement. Also, it wouldn’t hurt to check his estrogen and DHT.

Right now your son is in beginning of Tanner stage five puberty, the last stage before becoming a man. I would also test your son at 20-21 when testosterone is at its peak.

Total T testing can be plus or minus 50-70 ng/dL as far as accuracy goes.
