Quest works with PWNHealth LLC and its affiliated professional entities (collectively, PWN) to provide independent healthcare provider services associated with your lab test purchase. PWN services include physician oversight of all tests, including the ordering of tests and the evaluation of results once available. If one or more of your results indicates that you need prompt attention, you will receive a call directly from the PWN care coordination team. Additionally, if one or more of your results is for a positive sexually transmitted disease (STD) or HIV result, you will receive a call directly from the PWN care coordination team. You will have the ability to speak with a PWN healthcare provider to discuss the lab results, and in some states, the Licensed PWN healthcare provider may be able to provide treatment. Before submitting payment for your purchase, you will see the fees collected on behalf of PWN for their services to you.

If you would like to speak with a member of the PWN care coordination team or a PWN healthcare provider to discuss your results, you can contact PWN Monday to Friday 9:00 AM to 5:30 PM EST at 1.855.205.6146.

Additionally, some tests are not available to people of a specific sex or age. Some tests may not be eligible to combine with other tests. Lastly, some tests may be purchased only once per customer in their lifetime. Examples are but not limited to the Lipoprotein(a)/Lp(a) Test and High-Risk Heart Health Lipid and Lp(a) Panel.

You may be able to purchase multiple home collection kits for some tests during a single purchase. Review the product page to see if you can purchase several home collection kits during a single purchase.

An acknowledgement page will appear after you complete your checkout. Once your purchase is processed, you will get a purchase confirmation email from Quest, sent to the email address you used at checkout.

You may live in a state where our tests are not available, or your age or gender may prohibit a specific purchase. Please confirm that there are no duplicate tests in your cart and that your address is not a P.O. Box as Quest can only accept a street address.
