Understanding Lab Tests for Hirsutism
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Hirsutism is a condition characterized by excessive male-pattern hair growth in women, typically appearing on the face, chest, back, and other areas where men usually grow hair. This condition is primarily caused by elevated levels of androgens (male hormones) in the body, making hormone testing essential for diagnosis and treatment planning.
Recommended Test
Testosterone, Free, Bioavailable and Total, LC/MS/MS
This comprehensive testosterone test is crucial for diagnosing hirsutism as it measures all forms of testosterone in the blood. Elevated levels of bioavailable testosterone in females are a primary cause of hirsutism, leading to unwanted male-pattern hair growth. The LC/MS/MS method provides highly accurate measurements of free, bioavailable, and total testosterone levels, helping to identify the hormonal imbalance responsible for the condition.

The Role of Hormone Testing in Hirsutism
While hirsutism is diagnosed through clinical examination and assessment of hair growth patterns, blood tests are fundamental for identifying the underlying hormonal imbalances causing the condition. These tests help healthcare providers determine the specific cause and develop an appropriate treatment plan.
Understanding Your Results
Elevated testosterone levels, particularly bioavailable testosterone, can indicate various underlying conditions such as polycystic ovary syndrome (PCOS), adrenal disorders, or other hormonal imbalances. Your healthcare provider will interpret these results alongside your symptoms and medical history to determine the most appropriate treatment approach.
