Blood tests may be a useful screening tool for obstructive sleep apnea and potentially superior to current diagnostic methods, revealed study published in Nature and Science of Sleep.

The study, which used male participants, found that concurrent elevations of haemoglobin A1c (HbA1c), C-reactive protein (CRP) and erythropoietin (EPO) indicated that a patient may have obstructive sleep apnea. These tests were shown to correlate with disease severity and may assist in triaging patients for diagnosis and treatment.

In a statement, the authors said that they anticipated that use of objective blood tests will improve screening accuracy and timely diagnosis, improve patient management, decrease the incidence of diabetes and cardiovascular disease, and decrease healthcare costs.

Professor Steven Shea, Editor-in-Chief for Nature and Science of Sleep and founder of one of the first clinical sleep laboratories in the UK commented, "Diagnosis for sleep apnea usually requires expensive overnight polysomnography. An accurate, simple, quick and cheap screening test would be ideal." He went on to add that "Signs of sleep apnea detected from a blood sample is an important step in that direction and is particularly relevant in this cohort of non-obese men with sleep apnea."
