A Blood Test for Sleep Apnea?

Screening for obstructive sleep apnea (OSA) can be problematic. For example, polysomnographic data may be insufficient for determining whether a person has OSA if a sensor is dislodged for a substantial amount of time during a home sleep apnea study or if a patient has difficulty sleeping in a strange bed in a sleep laboratory.

A simple screening test could be helpful in detecting people who may have undiagnosed OSA. To this end, scientists have investigated several biomarkers (e.g., inflammatory substances, proteins) in the blood of people with OSA with the hope of using them as a screening test. No biomarker has been developed for clinical use. However, a few biomarkers appear to be promising candidates.

In the Q4 2017 issue of A2Zzz, Regina Patrick, RPSGT, RST, addresses some of the recent advancements in blood testing, helping to determine if they can become accurate tests for sleep apnea.

Her article, “A Blood Test for Sleep Apnea?” is one of four designated CEC articles in this issue of A2Zzz.
