Request A Test Promo Codes & Coupons February 2026

Your Request A Test promo code likely isn't working due to expiration, test-specific restrictions, or applying it to already discounted items. Many codes have specific limitations on which tests they can be applied to.

Common scenarios include entering an expired code, using it on non-eligible tests, or attempting to apply it to items that already have discounts. Request A Test policies typically limit one code per order with no stacking, and there are exclusions for industry discounts.

If your code isn't working, try these steps:

1. Verify the code is still active and note any restrictions.
2. Ensure your cart has qualifying tests (e.g., HEART10 works only for Heart Health tests).
3. Clear your browser cache, log out and log back in, then re-enter the code in uppercase.
4. If your code is expired, look for fresh alternatives like ATE20 for sitewide discounts.

Pro tip: Test codes on single-item carts first to confirm eligibility before adding more tests to your order.

Request A Test promo codes typically apply only to specific lab tests or categories, not all tests. Many codes are category-specific, such as those for Kidney tests, Sickle Cell Trait testing, or Heart Health panels.

While some "sitewide" codes may work on most orders, they often exclude certain tests or pre-discounted items. The terms and conditions usually specify exclusions like "tests not listed on our website" or tests that already have special pricing.

Category-specific codes (like HEART10 for Heart Health or MEN10 for Women's Health) are more common than truly universal codes. Always check the code details before completing your checkout to avoid disappointment.

Pro tip: Search the code name (e.g., "HEART10") on the Request A Test website to preview eligible tests instantly.

No, Request A Test does not allow combining multiple promo codes on a single order. Their policy strictly enforces "one coupon code per order" with no exceptions.

Users who attempt to stack codes typically receive errors like "Code already applied" when trying to add a second discount. This limitation applies to all types of promotional codes, whether they're percentage discounts or specific test offers.

Your best strategy is to select the single code that provides the highest discount for your particular test selection.

Pro tip: Pick the highest percentage code that matches your tests, like a 20% sitewide code, for maximum savings without encountering stacking failures.

On the Request A Test mobile checkout page, you'll need to:

1. Add your desired tests to your cart.
2. Proceed to checkout.
3. Scroll down below your cart summary to find the "Promo Code" or "Discount Code" field.
4. Enter your code in uppercase (e.g., HEART10) without any spaces.
5. Tap the "Apply" button before proceeding to payment.

Mobile users sometimes miss the promo field because it's positioned under the billing details after test selection. Valid codes will activate instantly, showing your savings in the order summary.

Pro tip: If you're having trouble locating the promo field, try using your mobile browser's incognito mode to avoid cookie conflicts that might hide the field.

If your Request A Test promo code shows "invalid" during checkout, it's usually because the code has expired, isn't eligible for your selected tests, or was entered incorrectly.

To resolve this issue:

1. Note the exact error message and check the code's terms and restrictions.
2. Try removing and re-adding tests to your cart to reset any conflicts.
3. Enter the code precisely in the promo field before proceeding to payment.
4. Test an alternative code like ATE20 (20% sitewide) if available.
5. Contact Request A Test support via their website chat if the problem persists.

Common reasons for invalid codes include exclusions for "industry discounted prices" or tests not officially listed on their website. Also, many promotional codes have short expiration windows.

Pro tip: Copy-paste codes directly from coupon websites to avoid typos, especially when entering them on mobile devices.
