These tests-typically polysomnography (PSG)-measure brain activity, eye movement, respiratory effort, oxygen saturation, and cardiac rhythm throughout the sleep cycle. Hospitals and accredited sleep centers rely on in-lab testing for complex cases where precision and continuous monitoring are crucial.

On the other hand, home sleep testing (HST) is revolutionizing accessibility. These portable diagnostic kits allow patients to record data such as oxygen levels, airflow, and heart rate in the comfort of their own homes. HST has become increasingly popular due to its affordability, convenience, and patient-friendly experience. The adoption of AI algorithms, wearable sensors, and cloud-based platforms further enhances diagnostic accuracy, enabling faster and more scalable sleep assessments.

By Indication

Among all conditions evaluated, obstructive sleep apnea (OSA) stands as the leading indication, holding nearly 44.8% market share in 2025. This dominance stems from the high prevalence of OSA globally-closely linked to obesity, cardiovascular disease, and hypertension. OSA's definitive diagnostic criteria and established treatment pathways also make it a major revenue contributor.

Other key indications include insomnia, restless leg syndrome (RLS), circadian rhythm sleep disorders, narcolepsy, and periodic limb movement disorders. Growing recognition of insomnia and circadian disruptions as public health issues is expected to expand testing volume across these segments, particularly among urban populations exposed to digital fatigue, stress, and irregular work schedules.

By End User

The market serves multiple end-user categories: hospitals, independent sleep clinics, and homecare or remote services. Hospitals and dedicated sleep centers currently dominate due to their infrastructure and availability of certified technologists. However, homecare testing services are the fastest-expanding end-user group, as healthcare shifts toward telemedicine, virtual consultations, and decentralized diagnostics. Subscription-based sleep health platforms and employer wellness programs are further integrating sleep testing into preventive care frameworks.
