Male hormone check: Get a complete picture with our comprehensive testosterone test

Testosterone is responsible for many essential male functions and characteristics—from your sex drive to your muscle mass. Some men experience symptoms when their free testosterone is low—even if their total testosterone is normal—which is why measuring both free and total testosterone can give you more answers.1 

Our comprehensive testosterone test provides insights on albumin and sex hormone-binding globulin (SHBG), total and free testosterone levels. Albumin and SHBG are proteins associated with testosterone and influence how much testosterone is available for bodily functions. By measuring albumin and SHBG, you get an accurate assessment of the free testosterone level in the body. Knowing albumin and SHBG levels alongside total and free testosterone can help you and your healthcare provider understand if your symptoms may be associated with high or low testosterone levels.

Note: This testosterone test is only clinically appropriate for individuals assigned male at birth (AMAB). If you’re an individual assigned female at birth (AFAB) seeking a testosterone test, please contact your healthcare provider.

What's Tested
  • Total Testosterone

    Testosterone is a key hormone that is responsible for regulating sex drive (libido), bone mass, fat distribution, muscle mass and production of red blood cells and sperm. This test measures the total amount of testosterone in your blood, including the testosterone that’s both attached and not attached to proteins (albumin and sex hormone-binding globulin).

  • Free Testosterone

    Free testosterone refers to the portion of testosterone that is not bound to proteins (albumin and sex hormone-binding globulin) and is readily available for use in the body. It is the active form of testosterone that regulates sex drive (libido), bone mass, fat distribution, muscle mass and the production of red blood cells and sperm.

  • Albumin

    Albumin is a protein that circulates in the blood and plays several roles. It provides nourishment to the tissues, carries substances like hormones and drugs in the blood and helps keep fluids within the blood vessels. Low levels of albumin may indicate malnutrition or a disease of the liver, thyroid or kidneys, among other conditions. Higher than normal levels of albumin may suggest dehydration or other underlying health issues. Additionally, albumin is a factor used to calculate the free testosterone level.

  • Sex Hormone-Binding Globulin (SHBG)

    SHBG is a protein produced mainly in the liver that attaches to sex hormones in your bloodstream. Its primary function is to regulate the amount of active sex hormones in your body. When SHBG binds to sex hormones, like testosterone, they become inactive and cannot be used by your tissues. Only the sex hormones that are "free," or unattached to proteins like SHBG, can be utilized in the body. By measuring the level of SHBG in your body, you can accurately calculate free testosterone levels.

  • Total testosterone and free testosterone tests are two different measurements of the male sex hormone testosterone found in the blood.


    A total testosterone test is often ordered by health care providers as an initial evaluation for low testosterone and it can provide a broader picture of your hormone health. It measures the total testosterone in your blood, including the testosterone that’s both attached and not attached to proteins. A free testosterone test measures the “free” testosterone that’s not bound to proteins and can be used by the body.3


    Our testosterone blood test measures total testosterone levels, which is a great starting point for assessing hormonal health. Our test does not measure free testosterone. Any abnormal results should be discussed with a health care provider to determine next steps.

  • Our comprehensive testosterone blood test measures total testosterone, albumin and SHBG levels and calculates free testosterone to help assess and provide insights on hormonal health. 


    Albumin and SHBG are proteins associated with testosterone. Testosterone is more tightly bound to SHBG than albumin. Higher levels of SHBG may indicate lower levels of free testosterone that are available for your body’s use. Conversely, lower SHBG levels may result in higher free testosterone levels. 


    Any abnormal results or concerning symptoms should be followed up with your healthcare provider to determine next steps.

  • The frequency of testing depends on your health status and if you are experiencing symptoms associated with low or high testosterone. Your provider may recommend repeat testing or additional tests to learn more about what may be causing your symptoms and/or the change in your testosterone level.


    Any abnormal results or concerning symptoms should be followed up with your healthcare provider to determine next steps.

  • Low testosterone (Low T) is more common than high testosterone in men. Low testosterone levels can lead to a variety of symptoms which can vary from person to person. If you are experiencing low T levels, you may notice:


    • Reduced sex drive and/or erectile dysfunction 
    • Low sperm counts and potential male infertility 
    • Increased body fat, often including breast enlargement 
    • Decrease in testicle size 
    • Loss of muscle mass and strength 
    • Decreased endurance 
    • Depressed mood 
    • Difficulty concentrating 
    • Reduced bone density


    These symptoms could also be caused by other conditions. It is recommended to consult with a healthcare provider if you have any questions about your results or symptoms.

  • Normal testosterone levels vary throughout the day, from person to person and throughout life.

    Consult with your healthcare provider if you have questions or concerns about the results of your testosterone levels blood test.

  • Some healthy habits that can help support your testosterone levels include:


    • Exercising regularly
    • Eating a healthy well-balanced diet
    • Maintaining a healthy weight
    • Limiting stress
    • Optimizing sleep quality
    • Avoiding excessive alcohol and drug use
