About The Test
Test Overview
Sex Hormone Binding Globulin (SHBG) is a protein produced by the liver that binds to sex hormones, regulating how much is available for the body to use. Abnormal levels can affect hormone balance and may indicate conditions such as polycystic ovary syndrome (PCOS), low testosterone, or liver disease.
Symptoms
Symptoms related to abnormal SHBG levels vary depending on the underlying hormone imbalance and may include:
- Irregular menstrual cycles
- Infertility
- Acne or excess hair growth (hirsutism)
- Decreased libido
- Fatigue
- Mood changes
- Erectile dysfunction
- Breast tenderness or enlargement in men
Test Includes
Sex Hormone Binding Globulin
Sex Hormone Binding Globulin (SHBG) is a protein produced in the liver that primarily binds to testosterone and estradiol, the major sex hormones in both males and females. It acts as a transport protein, carrying these hormones through the bloodstream. By binding to these hormones, SHBG reduces the amount of free, active hormones available for use by body tissues.
Recommended For
This test is often ordered when evaluating symptoms of hormone imbalance or conditions affecting testosterone or estrogen levels. It can help assess fertility issues, menstrual irregularities, or androgen disorders, and may be used to interpret total hormone levels more accurately.
Associated Conditions
- Polycystic ovary syndrome (PCOS)
- Hypogonadism
- Hyperthyroidism or hypothyroidism
- Liver disease
- Androgen disorders
Understanding Results
High or low SHBG levels can affect how much free, active hormone is available in the body. Results help your provider interpret total hormone levels and evaluate related symptoms. If your levels are outside the normal range, follow up with your healthcare provider for further evaluation and treatment guidance.
