What Is SHBG?
SHBG stands for sex hormone binding globulin.
SHBG is made mostly by the liver and helps carry sex hormones through the bloodstream.
When hormones are bound to SHBG, they are less available for the body to use. Because of this, SHBG can affect how much active or available testosterone and estrogen may be present.
What This Test Measures
This blood test measures the amount of SHBG in the blood.
- Test name: SHBG Sex Hormone Binding Globulin Blood Test
- Also known as: SHBG Test, Sex Hormone Binding Globulin Test, Testosterone-Estrogen Binding Globulin Test
- Sample type: Blood
- Purpose: Measures SHBG protein level
- Common use: Testosterone, estrogen, androgen and provider-directed hormone evaluation
Why Order an SHBG Blood Test?
An SHBG test may be ordered when a person or healthcare provider wants more information about how sex hormones are bound and available in the body.
This test may be considered for:
- Low testosterone evaluation

Low-Cost Hormone Testing Option
This SHBG test is a simple and affordable way to access hormone-binding evaluation.
SHBG is often ordered when total testosterone results do not match symptoms or when free testosterone calculation is needed.
For a more complete hormone evaluation, SHBG is commonly reviewed with total testosterone, free testosterone, albumin, estradiol, DHEA-S, LH, FSH, thyroid testing or other provider-directed labs.

- Men evaluating low testosterone symptoms
- Women evaluating excess androgen symptoms
- People with PCOS-related hormone concerns
- People with irregular menstrual cycles or infertility-related workups
- People following up on total or free testosterone results
- Customers who want low-cost hormone testing without insurance billing
Common Reasons for Testing
- Low libido
- Fatigue or low energy with hormone concerns
- Low testosterone symptoms
- Excess facial or body hair growth

- Irregular menstrual cycles
- Possible PCOS-related symptoms
- Follow-up to abnormal testosterone or estradiol results
SHBG and Testosterone
Most testosterone in the blood is attached to proteins, including SHBG and albumin.
Total testosterone measures both bound and unbound testosterone. Free testosterone measures the portion that is not attached to proteins.
SHBG helps provide context because high or low SHBG can affect how much testosterone is available to tissues.
SHBG and Women's Hormone Evaluation
In women, SHBG may be reviewed when symptoms suggest androgen imbalance.
Lower SHBG may be seen in some people with PCOS-related hormone patterns, insulin resistance or androgen excess.
SHBG should be interpreted with symptoms, medical history and other hormone tests.
SHBG and Thyroid or Liver Health
SHBG may be affected by several health factors, including thyroid function, liver function, body weight, insulin resistance, medications and hormone therapy.
If SHBG is abnormal, a healthcare provider may recommend additional testing to better understand the cause.
Important: SHBG Is Usually Not Interpreted Alone
SHBG is most useful when reviewed with other hormone markers.
Your healthcare provider may compare SHBG with total testosterone, free testosterone, estradiol, albumin, thyroid results, liver markers and symptoms.
SHBG alone does not diagnose a hormone disorder.
Medication and Supplement Note
Certain medications and hormone products may affect SHBG levels.
Birth control, estrogen therapy, testosterone therapy, anabolic steroids, thyroid medication, glucocorticoids and other medications may affect hormone results.
Do not stop or change medication unless instructed by a licensed healthcare provider.
Important Health Warning
If you have severe pelvic pain, sudden heavy bleeding, pregnancy-related concerns, severe testicular pain, chest pain, shortness of breath, fainting, severe headache, vision changes or any urgent medical concern, seek medical care promptly.
Do not use this test as a substitute for urgent medical evaluation, diagnosis or treatment.
Screening and Lab Access Only
LabReqs and SchoolTiters provide access to lab testing. We do not diagnose low testosterone, PCOS, infertility, thyroid disease, liver disease, hormone disorders or any medical condition.
This test may provide useful lab information, but results should be reviewed with a licensed healthcare provider, especially if symptoms are present, results are abnormal or treatment decisions are being considered.
Important Limitations
- This test measures SHBG only.
- This test does not include total testosterone, free testosterone, estradiol, albumin, DHEA-S, LH, FSH or thyroid testing unless ordered separately.
- SHBG does not diagnose hormone disorders by itself.
- SHBG can be affected by medications, hormone therapy, thyroid function, liver function, weight changes and insulin resistance.
- Abnormal results may require additional testing or medical evaluation.
- Do not start, stop or change medication based only on this result.
Before Ordering
- Confirm that you need an SHBG blood test.
- If your provider requested testosterone testing, make sure total and/or free testosterone are ordered if needed.
- Tell your provider about birth control, hormone therapy, testosterone use, thyroid medication, steroids, supplements and medical history.
- If you need a more complete hormone evaluation, ask whether testosterone, estradiol, albumin, DHEA-S, LH, FSH or thyroid testing should also be ordered.
- If your result is abnormal, review it with a licensed healthcare provider.
