Why are some tests only allowing me to purchase one time?

You can find an explanation of the tests on questhealth.com, but if you're not sure which lab test to choose, please consult your doctor.

Lab tests are not currently available in Arizona, Alaska, Hawaii, and Puerto Rico.

Note: In Arizona, Sonora Quest Laboratories offers testing that you can purchase through My Lab ReQuest™. Visit www.MyLabReQuest.com to learn more.

No. All tests are intended for users 18 years and older.

You will be asked to answer relevant medical questions for select tests. This will help to confirm that the test you’ve selected is right for you.

For tests requiring in-person sample collection, your purchase can't include more than one of the same test. You may live in a state where our tests are not available. 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. For tests that require a in-person sample collection you cannot purchase more than one of the same tests in 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.

No- the same person who purchased the test, must register for the test.

If you purchase a single test and a panel of tests, or two panels at the same time, some test components may overlap. In either case, we automatically deduct the cost of the overlapped component from your cart, so you only get charged once for the same test component.

For example, if you add a Basic Health Profile and a Cholesterol Panel to your cart, the price of the Cholesterol Panel will be deducted at checkout because the Cholesterol Panel is already part of the Basic Health Profile.
