Quest Diagnostics and Labcorp are the two national labs most doctors’ offices already use, and both now sell tests straight to the public. We opened the same eight tests on each company’s own storefront on November 13, 2026. Seven carried the identical list price. The differences that matter are a per-order fee, your insurance network, and the fact that a third party will often sell you the same draw for less.

For routine blood work the two are close to interchangeable. They run the same kinds of analyzers under the same federal rules, and a CBC from one is as valid as a CBC from the other. Three things separate them in practice.
Your insurance network. If a doctor orders the test and you want insurance to pay, this is the whole decision. Plans often name one lab as preferred. Use the other and you may be billed as out-of-network.
Which one is near you. Both have patient service centers across most of the country, but coverage is uneven town by town. A ten-minute drive beats a forty-minute one for a fasting morning draw.
Consistency. Reference ranges and methods can differ a little between labs. If you are tracking testosterone, thyroid or cholesterol over months, use the same lab each time so the numbers compare cleanly.
Paying Cash
You do not have to buy from Quest or Labcorp to be tested by Quest or Labcorp. Independent ordering services buy lab work in volume, add the physician order, and send you to the same draw sites. Their checkout prices are often lower than the labs’ own storefronts.
At our November 2, 2026 price collection, HealthLabs listed a lipid panel at $29 against $59 at both labs, a CMP at $39 against $49, and vitamin D at $59 against $75 and $99. HealthLabs states it charges no extra fees for the lab visit or results. Walk-In Lab and RequestATest work the same way; RequestATest adds a $4 service fee per order and cannot take orders from New York, New Jersey or Rhode Island.
Our Lab Test Price Index tracks 25 tests across seven of these services, with checkout fees included, so you can see the lowest current price for the test you need. If you want the lab’s own name on the receipt, see RequestATest vs Quest Direct and RequestATest vs Labcorp OnDemand.

FAQ
On their own consumer storefronts the two charge the same list price on 7 of the 8 common tests we checked on November 13, 2026: a CBC is $29 at both, a comprehensive metabolic panel $49, a lipid panel $59, hemoglobin A1c $39, TSH $49, total testosterone $69 and vitamin B12 $49. The one gap was vitamin D, $75 at Quest and $99 at Labcorp OnDemand. Quest also shows a $6 physician service fee on its product pages.
Neither has a meaningful accuracy edge for routine blood work. Both are large national laboratories that operate under the same federal CLIA rules, and both are the labs most doctors' offices already send samples to. Reference ranges can differ slightly between the two, so stick with one lab when you are tracking a number over time.
Use whichever one is in-network for your plan. Many insurers contract with one of the two as a preferred lab, and going to the other can turn a covered test into a full-price bill. Check your plan's lab directory before the draw.
Usually, yes. Independent ordering services such as HealthLabs sell tests that are drawn at Quest and Labcorp patient service centers, often below the labs' own storefront prices. The eight tests in our table total $418 at Quest and $442 at Labcorp OnDemand; the same eight totaled $307 at HealthLabs when we last collected its prices on November 2, 2026. See the Price Index for all seven services.
Not for consumer orders. Both storefronts, and the independent services that use their draw sites, include the physician order in the purchase. A few states restrict direct ordering; see how to get lab tests without a doctor.
Quest and Labcorp charge the same list price on most common tests, and neither is the more accurate lab. With insurance, use the one your plan prefers. Paying cash, choose the closer draw site and check a broker before you pay storefront prices.
