Sex Hormone Binding Globulin Blood Tests

Sex Hormone Binding Globulin (SHBG) is a laboratory test that measures the level of SHBG in the blood. SHBG is a protein produced by the liver that binds to sex hormones, such as testosterone and estrogen, in the bloodstream.

This test is usually done to evaluate and monitor hormone-related conditions. It can help in diagnosing and managing various conditions, including:

Hormonal imbalances: SHBG levels can be used to assess the balance of sex hormones in the body. High levels of SHBG may indicate a deficiency of sex hormones, while low levels may suggest an excess.

Polycystic ovary syndrome (PCOS): PCOS is a common hormonal disorder in women. SHBG levels can be used to evaluate the hormonal profile and monitor the response to treatment.

Hypogonadism: This condition refers to low levels of sex hormones in both men and women. SHBG levels can help determine the cause and guide treatment.

Hyperandrogenism: This condition is characterized by excessive production of androgens (male hormones) in women. SHBG levels can help assess the severity and guide treatment.

Liver disease: SHBG is primarily produced by the liver. Abnormal SHBG levels can indicate liver dysfunction or disease.

Monitoring hormone replacement therapy: SHBG levels can be used to monitor the effectiveness of hormone replacement therapy in individuals receiving treatment for hormonal deficiencies.

It is important to note that the interpretation of SHBG levels should be done in conjunction with other hormone tests and clinical evaluation to get a comprehensive understanding of your hormonal status.
