Availability varies by state. Direct-to-consumer lab testing is not offered everywhere. For example, Quest's consumer site has not offered testing in Arizona, Hawaii or Puerto Rico, and New York, New Jersey and Rhode Island have had restrictions on ordering tests without a clinician. Rules and provider coverage change, so confirm availability for your state at checkout.
