TB Test Near Me: Where to Get a TB Blood Test Today (Quest, Labcorp, Health Department, Urgent Care)

Every option below tests for TB infection — whether your immune system has encountered TB bacteria. They differ in how many visits they take, what they cost, and whether they use the blood test or the skin test.

• County or city health department. Most run TB clinics that place skin tests, and many offer the blood test. Often low or no cost, but hours are limited, walk-in days vary, and some restrict testing to people with a known exposure or a referral. Call first.
• Urgent care and retail clinics. Most urgent cares and many pharmacy clinics place the TB skin test; blood-test availability varies by location. Expect a visit fee plus the test, and — for the skin test — a mandatory return trip 48–72 hours later for the reading.
• Your employer or school. Hospitals and many nursing programs run their own occupational-health testing, sometimes at no charge to you. If yours does, use it — but check whether it fits your deadline, since campus and employee-health clinics often book out at the start of a term.
• A primary-care office. Works if you already have one. If you don't, the appointment, the referral and the visit fee are usually the slowest and most expensive part of the process.
• Any Quest Diagnostics or Labcorp patient service center, with an online order. You order the QuantiFERON blood test, a physician authorizes it, and you walk into the nearest location with the requisition — no appointment at most sites, no doctor's visit, one draw. This is the route the rest of this guide describes, because for a healthy adult who simply needs the test, it is the fastest and usually the cheapest.

Two tests are in use. The skin test (TST, PPD or Mantoux) is placed on your forearm and must be read by a trained professional 48 to 72 hours later — miss the window and it has to be placed again. It can read falsely positive in anyone who received the BCG vaccine in childhood, which is most people born outside the United States. The blood test (an IGRA — QuantiFERON-TB Gold Plus is the common brand) is one draw, is read by a lab instrument, and is not affected by BCG.

CDC encourages the blood test generally and prefers it for people who were BCG-vaccinated or who may not return for a reading. Most US universities and employers accept it, and many now specify it. The skin test is still the right or required choice in some situations — children under 5, serial-testing programs, and any form that names PPD or Mantoux specifically. If your paperwork says PPD, check with whoever is requiring it before you order a blood test; some programs will not accept a substitute. The full comparison is in TB blood test vs. skin test, and the four-visit baseline that hospitals use is explained in the two-step TB test.

One thing neither test does: neither the blood test nor the skin test can tell the difference between latent TB infection and active TB disease. Sorting that out is a clinician's job, which is why a positive result on either test leads to an evaluation rather than to a second test.

The direct route takes three steps and, in most metro areas, a single afternoon:

1. Order online. The QuantiFERON-TB Gold Plus blood test is $91.99 through TestWell. A licensed physician reviews and authorizes the order — that is what makes a doctor's visit unnecessary — and the requisition arrives by email, usually within the hour.
2. Walk into the nearest patient service center. Pick Quest or Labcorp at checkout, then use the lab finder or one of our city location pages to find the closest draw site with its hours and phone number. Most accept walk-ins; appointments are optional. Bring the requisition on your phone and a photo ID. In New York and New Jersey the draw happens at BioReference at the same price.
3. Get results in 3–5 business days. The CLIA-certified lab report, with the quantitative values and interpretation, posts to your portal and is the document schools and employers ask you to upload.

Locations by metro, with addresses, hours and phone numbers, checked monthly: Miami, Orlando, Tampa, Houston, Dallas, Austin, Los Angeles, San Diego, New York City, Newark, Chicago, Atlanta, Phoenix, Philadelphia — or browse every state.

Go in the morning if you can. The QuantiFERON sample has to reach processing within 16 hours of collection, so a morning draw makes the same-day courier run to the lab. It is also one of the sample-handling reasons behind indeterminate results, so it is not a detail to fight.

Negative. A negative result means TB infection is unlikely, but doesn't completely rule it out — particularly if you have symptoms or a weakened immune system. Timing matters too: it can take 8 to 10 weeks after exposure for these tests to turn positive. If you were recently exposed, a negative result should be repeated 8 to 10 weeks after your last exposure.

Positive. A positive result means your immune system has responded to TB proteins, which is evidence you've been infected with TB bacteria at some point. It does not tell you whether that infection is latent (dormant, not contagious) or active TB disease. These are different conditions with different treatments, and no blood test can tell them apart on its own. The next step is an evaluation with a clinician — usually a review of your symptoms and history plus a chest X-ray. Bring your result to your primary care clinician, an urgent care, or your county health department; health departments evaluate positive TB tests routinely, often at low or no cost.

Indeterminate. An indeterminate result isn't positive or negative — it means the test didn't produce usable information, most often because of sample handling, sometimes because of an immune response that can't be measured normally or a recent live-virus vaccine. The usual next step is a repeat draw. TestWell's redraw policy: if your QuantiFERON result comes back indeterminate, contact support within 3 days of the result and we'll issue a free redraw requisition.

Already had a documented positive? Don't retest. CDC guidance is that neither test should be repeated in someone with a documented prior positive or prior TB treatment — most people stay positive for life, and a repeat result won't change what happens next. What programs typically want in that case is proof of the prior result plus a chest X-ray or clinical evaluation.

Ordering a test online is the right move for a healthy adult who needs a result for a form. It is the wrong move in a few situations:

• You have symptoms — a cough lasting three weeks or more, coughing up blood, fever, night sweats, or unexplained weight loss. Be seen by a clinician; don't order a test and wait. A negative blood test in someone with symptoms does not rule out TB disease.
• You had a known exposure in the last 8–10 weeks. Test now if a program requires it, but plan on the repeat at 8–10 weeks after the exposure — and tell the health department, which manages contact investigations.
• The test is for a child under 5. Current CDC guidance still points to the skin test for young children, and TestWell serves adults 18 and over; pediatric TB testing goes through a pediatrician.
• Your form names the skin test. A PPD or Mantoux requirement, or a two-step baseline, has to be placed and read by a clinic — see the options above.

The spread is wide for the same test. Health departments are often low or no cost but limited in hours and eligibility. A clinic route — urgent care, travel clinic, campus health — commonly runs $150–$350 for the blood test once the visit fee is included, and the skin test adds a second visit. Quest's own consumer site lists the QuantiFERON test at $149. Through TestWell it is $91.99 with no visit fee, physician authorization included, drawn at the same Quest or Labcorp locations. If your form also asks for MMR, varicella or hepatitis B titers, the Pre-Enrollment Health Panel puts all four in one draw. HSA and FSA cards are accepted; no insurance is needed.
