Ask a healthcare provider for a blood test
Get a total testosterone test in the morning, usually between 7 a.m. and 10 a.m.
Repeat the test on a different day if the result is low
Ask whether free testosterone, SHBG, LH, FSH, and prolactin should also be checked
Avoid testing during acute illness if possible
Follow any fasting or medication instructions from the lab or clinician
Use a certified medical laboratory
Review the results with a healthcare professional
Do not rely on at-home saliva or urine tests alone for diagnosis
