TB Blood Test Cost Without Insurance (2026): QuantiFERON

Compare every service on the best blood tests page or see price per measured marker.

What a TB blood test is

The CDC says TB blood tests "use a blood sample to find out if you are infected with TB germs." It explains that "the tests measure how your immune system reacts when a small amount of your blood is mixed with TB proteins" (CDC). The two common brands are QuantiFERON-TB Gold Plus and T-SPOT.TB, often grouped as IGRAs. This page covers price and where to order. What a result means is a question for your clinician.

TB blood test price by seller

Read from each seller's own page. Fee on top is what the seller adds beyond the list price.

Mito's page notes that prices are snapshots, so confirm the checkout total before ordering. Other lab-test stores may list a TB test too; we could not read a current page for them, so we left them out instead of guessing. For the same store-by-store method on other tests, see the PSA test cost guide and the no-insurance price hub.

TB blood test versus skin test

The CDC says "TB blood tests are the preferred test for people who have received the TB vaccine" and that, "unlike the TB skin test, TB blood tests are not affected by BCG vaccination" (CDC). BCG is a TB vaccine given in many countries outside the US.

The visits differ too. For the skin test, a provider puts a small amount of testing material under the skin. Then, the CDC says, "You will need to return to your health care provider in two to three days to see if there is a reaction." The blood test needs one trip to a lab. Employers, schools and programs may say which test they accept, so check the requirement first.

What happens after a positive result

A positive result is not the end of the story, and it is a reason to see a clinician. The CDC says "A positive test result for TB infection means you have TB germs in your body," and that a provider "will do other tests to determine if you have inactive TB or active TB disease." Those tests "may include a chest x-ray, and a test of the sputum (phlegm) you cough up" (CDC). Those follow-up costs are not in the prices on this page.

Who the CDC says should get tested

The CDC says people at higher risk of infection should get tested. Its list includes people who were born in, or often travel to, countries where TB is common. It also names people who "recently spent time with someone who has active TB disease" and people who "work in places where TB is more likely to spread" (CDC, read 9 Nov 2026). Whether you need a test is a question for a clinician or the employer or school asking for it.

Who can order a TB blood test without a doctor visit

Labcorp OnDemand says "a healthcare provider will review and approve your test requests; no healthcare provider visit is required," and that the test "must be taken by purchaser" (Labcorp). It also notes that vaccines such as MMR, Varicella and Yellow Fever "may affect test results" and suggests testing the same day as vaccination or waiting 4-6 weeks.

Where you cannot order it

Mito's page says its Labcorp offer is "Available outside NY, NJ, RI, and HI, subject to local collection availability," with a separate offer for New York and New Jersey. Labcorp's page lists no state limit for this test. Our state guide and ordering your own blood test explain the rules.

TB tests for work or school

Many people order a TB blood test because a job or school asks for proof. A self-ordered result may or may not satisfy that request, so ask the requester whether a lab result from a direct-to-consumer store is accepted and what documentation they want.
