Follow the kit instructions to collect a saliva, urine, or finger-prick blood sample
Send the sample to the lab if required
Review the results in the lab’s report or online portal
Test in the morning, when testosterone is usually highest
Avoid testing during illness, poor sleep, or after heavy exercise if possible
Repeat the test on a different day if results are abnormal
Compare results with the reference range provided by the lab
Consult a healthcare professional if results are low, high, or symptoms are present
