Quest Code Checks, Day by Day

Every Quest code check from the last 13 days, plotted by the day it ran. Green is how many came back working. Red is how many questhealth.com would not accept. That is the checkout testing you did not have to sit through yourself.

where this data came from:
50 automated cart runs7 web search results3 shoppers reporting back

3 of these results came from shoppers telling us whether a code worked; the rest come from automated checks and the other sources above. Last confirmed working on . Codes that stop clearing get pulled off this page automatically.

What These Numbers Mean

A code check is one result for one code. Most are our agents applying it to a real cart and reading the order total before and after; the rest come from tracked orders and from shoppers reporting back, as broken down above. Worked means the code was accepted and the total went down. Would not apply means questhealth.com refused it on that cart. That is not the same as the code being fake. The usual reasons are:

  • It expired or the store switched it off after it was published.
  • It was single-use and had already been redeemed.
  • It only covers certain categories, brands or individual products.
  • The cart did not reach a minimum spend.
  • It is limited to new customers, a first order, or an email sign-up.
  • It cannot be combined with an active sale or another code.
  • It is tied to a different country, currency or membership.

So a code that failed one check can still work on your cart, and the success rate (checks that worked divided by all checks) is best read as how easily Quest discounts apply in general, not as a verdict on any single code. Hover any bar in the chart to see that day on its own.

  2. early January
    New Year Health Resolution Sale

Locate the Code Box at questhealth.com

The agents tested the code. Entering it is the one part we leave to you. Here's exactly where the Quest promo code goes at checkout.

Follow the shopper-submitted screenshots below to spot the Quest promo box and apply your code. Miss a step and even a working code does nothing, so the agents mapped every one for you.

Before You Buy at Quest

What shoppers ask most about Quest.

›Which lab tests or categories are excluded from discount codes?

Promo codes and affiliation discounts exclude physician fees and specific promotional packages like the Elite Health Profile. State regulations also restrict code usage in Alaska, Arizona, and Hawaii.

›Can multiple promo codes or promotional discounts be combined on one order?

Promotional offers and discount codes cannot be stacked together on a single transaction. Each purchase is limited to one eligible promo code or automatic discount.

›Why was a valid ID.me or Student Beans verification code rejected at checkout?

Verification codes may be refused if the billing address or state falls within restricted jurisdictions like Arizona or Hawaii. Ensure your verification profile matches your active session credentials.

›Why are online lab test purchases restricted in certain U.S. states?

State laws in Alaska, Arizona, and Hawaii prohibit consumer-initiated direct lab test ordering without a physician's direct consultation. Orders originating from these states cannot be processed on the platform.

How We Verify Quest Codes

Nothing goes up here on trust. A Quest code is collected, applied to a real questhealth.com cart, dated the last time it took money off an order, scored on what came back, and pulled once it stops clearing. Promotions have no code to run through a checkout, so those are dated when they go live and dropped when they lapse. Here is how far that has got on this page, and every change the agents logged along the way.

The agents keep retesting every Quest code on this page. No one here vouches for a code they did not watch work. If one slips through expired, take the next on the list. We keep backups. Want more codes we have watched work? See top-rated verified promo codes from every store.

Help Other Quest Shoppers

Not every Quest code reaches us from the store. 14 codes on this page were first submitted by shoppers. They have also sent back 3 checkout results in the last 13 days, telling us which codes worked on a real cart and which came up empty. Wherever a code comes from, it still has to pass the same cart test before it goes up here.

Have a code we missed?

Send it over and the agents will run it through a real questhealth.com cart. If it works, it lands here with the test behind it.

Did a code work for you?

Open any Quest code above and tell us whether it worked. It takes one tap, no sign-up, and a code that keeps failing gets pulled off the page.
