[Where do we perform sleep test: In the laboratory or at home?].

Obstructive sleep apnea syndrome (OSAS) is an important public health problem seen in 14.3% of male, and 5% of female population which leads to higher morbidity, and mortality rates because of its outcomes effecting many organ systems including cardiovascular, and cerebrovascular systems. Despite its higher prevalence in community, sleep laboratories both in our country, and in the world remain incapable of diagnosing these patients, and 80-90% of the cases with OSAS can not be diagnosed. As an alternative to gold standard polysomnographic examinations this desperate condition revived the use of more practical, and less expensive portable monitorization devices which can be used at home without the need for help of a technician. In this article we will discuss whether application of sleep test on a patient with suspect OSAS in the laboratory or at home will be more appropriate regarding effectiveness, and reliability of the test in the light of the scientific data.
