Home sleep tests are by far the most affordable at about 1/4 the cost of an in-lab sleep study. For this reason, many insurance companies require a HST as a first-line diagnostics tool. With proper screening, up to 75% of patients suspected of having moderate to severe sleep apnea will only need to have a HST performed to get their diagnosis.
An HST cannot be used to test children and other sleep related complaints such as excessive daytime sleepiness without snoring, frequent nocturnal awakening, restless leg syndrome (RLS), periodic limb movements (PLM), and parasomnia.
