question from a user
I’m a little confused by my blood test numbers and reference ranges. Is 555 ng/dl total testosterone and 11.7 pg/ml free testosterone low. The free test was within the reference range for my lab but everything I’m seeing online tells me that it is low.

We would say that depends on your age, but if you are below 50 years old, then yes, your free T would be considered low. Also, T levels drop by 30% throughout the day. So if that was an early morning test, then your free T is closer to 7 in the afternoon.
