Categories: ,

The Sex Hormone Binding Globulin (SHBG) test measures the level of SHBG in the blood. SHBG is a protein produced primarily by the liver that binds to sex hormones, specifically testosterone and estrogen, and regulates their availability to tissues throughout the body. By binding these hormones, SHBG controls the amount of free (bioactive) hormones that are available for the body to use. The SHBG test is often used to evaluate hormonal imbalances, especially in cases of infertility, sexual dysfunction, or polycystic ovary syndrome (PCOS).

    Description

    Purpose of the Test:
    • Assess hormone imbalances in both men and women
    • Evaluate the free testosterone levels, which are influenced by SHBG, to help diagnose conditions like PCOS, hypothyroidism, or androgen excess
    • Investigate sexual dysfunction, infertility, or irregular menstrual cycles
    • Monitor conditions such as liver disease, diabetes, or obesity, which can influence SHBG levels
    • Determine the balance between bound and free sex hormones to better understand hormone activity and related symptoms

    What the Test Involves:
    • A blood sample is drawn from a vein in your arm
    • The test measures the SHBG concentration in the blood
    • Results are interpreted in relation to other hormone levels, particularly testosterone and estrogen, to assess hormonal balance
    • High or low levels of SHBG may indicate the need for further testing or help direct appropriate treatment for underlying conditions
