I was reading the post about 17OHP so I asked my son’s endo what were ’good’ ranges? She said she doesn’t use 17OHP for ’control’ but rather the androgen numbers. She said that was mostly due to the fact that 17OHP levels are affected by time of blood draw, as others have already said. So why do we even check this?

So I guess my real question is, which test is the most reliable for over/undersuppression? Which lab results should I be paying most attention to? Does anyone know? Thanks.
