Blood levels: To check testosterone you have to do specific laboratory blood test they can do a total testosterone or A more accurate test which is a total and a free testosterone Level. That’s the only way to know testosterone levels .They can also do a FSH level LH level which check for endocrine problems associated with low libido and low testosterone .Also a prolactin level which checks for a prolactinoma

Testosterone level: Agree with Dr. Kuitems. Testosterone level can't be deduced by look at blood counts or blood chemisty. A doctor has to specifically request that testing.
