What this test is
This test measures the amount of testosterone in the blood, including total testosterone (bound to proteins and free) and free testosterone (unbound and biologically active). It is used to assess hormone imbalances and diagnose conditions such as hypogonadism or infertility.
What it measures
- Total Testosterone — Measures all testosterone in the blood, both bound to proteins and free.
- Free Testosterone — Measures the unbound, biologically active portion of testosterone.
- Sex Hormone Binding Globulin (SHBG) — Often measured to calculate free testosterone, as it binds to testosterone.
- Albumin — Another protein that binds testosterone, sometimes used in calculations.
What the test involves
A standard blood draw is performed, usually from a vein in the arm. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test to investigate symptoms of low testosterone, such as fatigue, decreased libido, or erectile dysfunction, or to evaluate infertility or menstrual irregularities. It can also be used to monitor hormone therapy or diagnose pituitary or testicular disorders.
Preparation
Preparation instructions vary by laboratory, so follow the specific instructions provided by the collection lab. Typically, a morning blood draw is recommended because testosterone levels are highest in the morning.
How results are reported
Results are reported as numerical values for total and free testosterone, often with reference ranges. Reference ranges can vary significantly between laboratories, so results should be interpreted in the context of the lab's own ranges and your clinical history.
Before you go
- Whether fasting is required before the blood draw.
- The best time of day for your appointment.
- Any medications or supplements that might affect results.
