Understanding Lab Tests for Male Pattern Baldness
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Male pattern baldness (androgenetic alopecia) is primarily diagnosed through visual examination of hair loss patterns and family history. There is no single blood test to diagnose male pattern baldness itself; however, lab testing can be fundamental for understanding the underlying hormonal factors that contribute to this condition.
Recommended Test
Dihydrotestosterone, (DHT) LC/MS/MS
This test measures DHT levels in the blood using advanced laboratory methods. High levels of DHT can bind to receptors in the scalp and cause hair follicles to shrink and eventually stop growing, leading to male pattern baldness. Understanding your DHT levels can provide insight into the hormonal component of hair loss.

Why Blood Testing is Important for Hair Loss
Male pattern baldness is largely influenced by genetics and hormones, particularly dihydrotestosterone (DHT). Blood tests can help assess hormone levels that may be contributing to hair loss, providing valuable insights for understanding the biological mechanisms involved and potentially guiding treatment decisions.
Understanding Your Results
DHT testing results should be interpreted by a healthcare provider who can correlate hormone levels with your specific hair loss pattern and medical history. Elevated DHT levels may help explain the biological basis of hair loss and inform treatment strategies, though individual sensitivity to DHT varies among people.
