To check your testosterone level, you typically need a blood test. This test measures the amount of testosterone in your blood, including both free (unbound) and protein-bound testosterone. This simple procedure is easily administered by a medical professional in a lab setting. Many labs also offer at-home testing options for added convenience.
Understanding the Testosterone Blood Test
A testosterone blood test is a straightforward procedure to determine the level of this crucial hormone in your body. The results are usually given in nanograms per deciliter (ng/dL), with normal ranges generally falling between 300 and 1000 ng/dL. However, the normal range can vary depending on factors like age and sex.
-
Total Testosterone Level: This measures both free and bound testosterone. Some doctors may recommend taking samples at different times (e.g., before noon) for a more accurate picture.
-
Free Testosterone Level (Sometimes Ordered): This measures the amount of testosterone not attached to proteins, which is the biologically active form. This may be ordered separately in certain cases.
Where to Get Tested:
You can obtain a testosterone test from various sources:
- Your Doctor: This is the recommended method, ensuring proper interpretation of your results and medical guidance.
- Commercial Labs: Many commercial labs offer the test, either through an appointment at their facility or with at-home collection kits. Examples include Quest Diagnostics and LabCorp.
- At-Home Testing Kits: Companies like Everlywell and Ada offer at-home testosterone testing kits, providing a convenient way to collect a sample for analysis. However, it's still advised to discuss the results with a doctor.
Why You Might Need a Testosterone Test:
A doctor may order a testosterone test if you experience symptoms related to low or high testosterone levels, which can vary depending on your sex. These symptoms can include fatigue, decreased libido, or changes in body composition. It's important to consult with a medical professional to determine if a test is needed based on your individual health situation.
