Understanding Lab Tests for Sleep Apnea
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Sleep apnea is a sleep disorder characterized by repeated interruptions in breathing during sleep. The condition is primarily diagnosed through sleep studies and physical examination, not blood tests. However, lab testing plays an important supportive role in identifying underlying factors that may contribute to or worsen sleep apnea.
Recommended Test
Testosterone, Total, Male, IA (MALES ONLY)
This test measures total testosterone levels in men. Elevated testosterone levels can worsen sleep apnea symptoms by affecting breathing patterns and sleep quality. Monitoring testosterone is important for understanding hormonal factors that may contribute to the severity of sleep apnea.

Why Blood Testing is Important for Sleep Apnea
While there isn't a single blood test to diagnose sleep apnea itself, testing is fundamental for assessing hormonal imbalances and other factors that can influence the severity of the condition. Blood tests help healthcare providers understand potential contributing factors and guide comprehensive treatment approaches.
Understanding the Connection
Hormonal imbalances, particularly elevated testosterone in men, can influence the severity of sleep apnea. By identifying these contributing factors through blood testing, healthcare providers can develop more comprehensive treatment plans that address both the sleep disorder and underlying hormonal issues.
