A Free testosterone Test is done to measure the active form of testosterone. This test should be conducted in the morning between 7 and 10 am, as the level of testosterone is highest during this time. It can be used for diagnosing certain medical conditions. There are different forms of testosterone in blood that may be measured to help diagnose certain health problems. Most of testosterone is attached to proteins, the proteins prevent your tissues from using the testosterone right away, which helps control the amount of active testosterone in your body.

Free testosterone is the active form of testosterone that is not attached to proteins, and acts on your tissues. It is a small portion of your total testosterone that acts on your tissues. A totalย testosterone test measures free testosterone and testosterone thatโ€™s attached to proteins. This is the most common type of test. A bioavailable testosterone test measures free testosterone and testosterone thatโ€™s loosely attached to albumin. This test isnโ€™t commonly done. The free T levels are affected by various conditions like obesity, ageing, and infections. The free testosterone test can provide your healthcare provider with more information about your health condition when your total testosterone is low.

They will insert a needle in the vein around your arm to draw blood. The blood will be collected in the vial attached to the needle. After drawing the blood, the technician will apply cotton on the puncture site to restrict the flow of blood. Once the blood has been collected, it will be sent to the lab for detailed analysis.
