Extensive studies have been conducted worldwide to ensure the efficacy of sampling.

Reliable self-sampling eliminates the need for a physical examination with a doctor, saving time, money and resources for many individuals while allowing users to be confident that their sampling has been done correctly and with comfort.

The efficacy of screening is dependent on the participation rate which can vary between 10-80% due to lack of time, fear, embarrassment, discomfort and cultural reasons. Community based screening programs can therefore be improved by offering the option of self-sampling and have been proven effective.
