What is the minimum age requirement for a child to use the saliva kits?

We find that typically children five years or older are able to adequately donate enough saliva for the test requirements. However, this varies from child to child. We require the full 2 mL of saliva, no matter the age of the person tested. If a child is unable to complete the full 2-mL donation, you have the option to use our assisted saliva collection kit or submit a blood sample.
