The top offer for Private MD Labs is the 15% off promo code at the top of this page, which takes 15% off all online blood tests and is best if you want a straight percentage off a single test or multiple tests in one order. It is a website only code and is applied at checkout, so use it if you prefer a guaranteed discount on the tests in your cart.
Low cost single test (from $104 to $132) If you are buying a single entry level test such as the Deluxe Checkup from $104, the 15% promo code is the simplest saving. On a $104 Deluxe Checkup, the promo code takes 15% off, reducing the price to $88.40 and saving you $15.60. If the specific test is part of the “up to 21% off best selling tests” promotion, that sale rate would be better; for example, at 21% off the same $104 test you would pay $82.16 and save $21.84, but the sale applies only to selected products and availability may vary.
Mid range test or Ozempic eligibility test (example $132) The code still helps you. On the Ozempic eligibility test from $132, the 15% promo code reduces the price to $112.20, a $19.80 saving. If that test is eligible for the up to 21% best selling tests sale, 21% off would be cheaper: $104.28, a $27.72 saving, but that sale is subject to availability and selected items only.
Buying multiple tests or larger orders If your cart is several tests or a higher total, the 15% promo code scales with the total and is applied automatically at checkout. The subscription sale that offers up to 23% off applies to subscriptions rather than one off tests, so if you are signing up for a paid subscription service the subscription discount could beat the 15% code, but it is valid on selected products for subscribers only and may not apply to one off test kits.
Newsletter signup The newsletter signup is for special offers and promotions and is not the main offer here. It may give first time or subscriber promotions later, but it is not the headline option and does not replace the 15% promo code for immediate use.
Our records show six offers listed for Private MD Labs in the 12 months to October 2026, with one percentage code in that period (the biggest was 15% off in October 2026). Our team carried out one checkout test across one offer in that 12 month window and kept a screenshot as proof.
When choosing, take whatever option leaves the lower total for the same items. If a test in your cart is explicitly included in the up to 21% best selling tests or the up to 23% subscription offer and that stated percentage applies, use that sale instead of the 15% promo code. There is no stated rule on stacking, so treat each offer on its own and apply the single discount that yields the lower final price.
