About Compare Lab Tests

Blood testing is priced like airline seats. The same panel, drawn at the same Quest or Labcorp, can cost three times as much depending on who you order it through — and nobody publishes that comparison, because the people who could are the people selling the tests. This site exists to publish it.

What it tracks

147 tests from 27 direct-to-consumer vendors: in-lab panels, at-home kits, gut and microbiome tests, and membership programs. Prices are read from each vendor's own public pages. Every price carries the date it was last confirmed and a link to the page it was read from, so any number here can be checked against its source in one click — and if the two disagree, the source wins and we want to hear about it.

Marker coverage is built by hand from each vendor's own test documentation rather than from their headline count, because vendors count differently — a panel advertised as "80+ biomarkers" often counts calculated ratios as separate markers. The methodology page sets out how all of this works in detail.

Who it is independent of

Everyone listed on it. This site is not owned by, funded by, or operated by any testing vendor, laboratory or healthcare provider. No vendor sees a page before it is published, has any say in what it says, or can pay for a position, a mention or a kinder description. There is no outside investment and no advertising.

What that leaves is affiliate commission, which is disclosed on every page that carries a paying link or code. Here is the part that matters: every table sorts by price, low to high, and nothing else. When a vendor that pays a commission is the most expensive option it appears at the bottom, which happens on this site — that is not a flaw in the arrangement, it is the whole point of it. A commission changes what the site earns, not what it shows.

What it is not

It is not medical advice, and it is not written by clinicians. This site can tell you what a panel costs and which biomarkers it measures. It cannot tell you which test you should take, what a result means, or whether testing is a good idea for you. Those are questions for a clinician, and a price comparison is not a substitute for one.

It also does not rank vendors as "best". Marker count is not a measure of clinical usefulness — a well-chosen panel of twenty can be worth more than a scattershot eighty — so the tables compare price and coverage and leave the judgement to you.

No byline

The site carries no author name. It is not built around anyone's opinion and there is nothing here you are being asked to take on someone's authority: every price links to the vendor page it came from, every marker list is published, and the whole dataset is downloadable. Check it rather than trust it. If something is wrong, the fix is a correction, not a credential.

Getting it wrong

Prices move and mistakes happen. A wrong number on a site whose entire claim is accurate numbers is the failure that matters most here, so corrections go to the front of the queue — the contact page is how to send one. The full price dataset is also published as a CSV with no affiliate links in it, free for anyone to take, check and republish.
