Endocrine / Hormones
Also known as: Free T, unbound testosterone
No common urgent flag from this test alone. However, if you experience sudden severe symptoms like chest pain, difficulty breathing, or severe weakness, seek immediate medical attention.
This test checks how much testosterone is in your blood. It looks for testosterone that is not stuck to other things. This "free" testosterone is what your body can actually use. It helps your body do things like build strong bones and muscles.
Your doctor orders this test to help find out why your testosterone levels are unusual. This is especially true if you have symptoms. The test can also check your health if you are taking certain medicines or hormone treatment.
Reference ranges for free testosterone can vary depending on the lab, your age, sex, and other health conditions. Your doctor will interpret your results based on these factors.
