Tuberculosis Test Near Me: Types Cost Accuracy & Where to Get Tested

A tuberculosis (TB) test checks whether you have been infected with Mycobacterium tuberculosis. Two main tests are used worldwide: the tuberculosis skin test (TST/Mantoux) and the tuberculosis blood test (IGRA). Most clinics hospitals and public health centers offer same-week appointments and results are ready in 48–72 hours (skin test) or same day to a few days (blood test).

What Is a Tuberculosis Test?

Tuberculosis is a bacterial infection that mainly affects the lungs and spreads through the air when an infected person coughs or sneezes. A TB test does not diagnose active disease by itself it tells you whether your immune system has ever reacted to TB bacteria. A positive result means you need further evaluation chest X-ray sputum test) to check whether the infection is latent (inactive not contagious or active (contagious needs treatment).

Types of Tuberculosis Tests

  1. TB Skin Test (TST / Mantoux / PPD)
  • A small amount of tuberculin is injected under the skin of your forearm.
  • You must return 48–72 hours later so a trained provider can measure any swelling (induration).
  • Requires two visits.
  • Widely available and low-cost.
  1. tuberculosis Blood Test (IGRA)
  • A single blood draw measures how your white blood cells respond to TB-specific proteins.
  • Only one visit needed; results usually available within 24–72 hours.
  • Not affected by prior BCG vaccination so it’s preferred for people who received the BCG vaccine as children.
  • Two FDA-approved options are commonly used: QuantiFERON TB Gold and T SPOT.TB.
  1. Chest X-ray and Sputum Test
  • Used after a positive skin or blood test to check for active TB disease in the lungs.
  • Sputum smear/culture confirms active contagious TB.

Who Should Get Tested?

  • Anyone with a persistent cough (3+ weeks) unexplained weight loss night sweats or fever
  • People who’ve been in close contact with someone diagnosed with active TB
  • Healthcare workers teachers and childcare staff (often required annually)
  • Visa or immigration applicants (many countries require an approved TB test as part of the application)
  • People with HIV or weakened immune systems
  • Travelers from or to high TB burden countries

Where to Get a TB Test Near You

TB tests are available at:

  • public health department clinics (often free or low-cost)
  • Hospitals and diagnostic labs
  • Urgent care and occupational health clinics
  • Government-approved panel physicians (required for visa/immigration TB tests)

Tip: If you need the test for a visa application check your destination country’s official immigration or embassy website for its list of approved clinics before booking since results from non-approved centers are typically not accepted.

How Accurate Are TB Tests?

Both TST and IGRA are reliable screening tools but neither is 100% definitive on its own:

  • A false positive can occur with the skin test in people previously vaccinated with BCG.
  • A false negative can occur in people with weakened immune systems.
  • A positive result always requires follow-up (chest X-ray and clinical evaluation) to confirm whether the infection is latent or active.

What Happens After a Positive Result?

  • Your provider will order a chest X-ray to look for signs of active TB in the lungs.
  • If active TB is suspected sputum samples are tested.
  • Latent TB infection is treated with a short course of antibiotics (commonly 3–4 months) to prevent it from becoming active disease.
  • Active TB disease requires a longer multi drug treatment course under medical supervision typically 6 months or more.

Cost of TB Testing

Cost varies widely by country clinic type and whether it’s for medical or immigration purposes:

  • Public health clinics often test for free or at low cost as part of TB control programs.
  • Private hospitals and visa-approved panel clinics charge a set fee which is separate from any visa application fee.
  • Blood tests (IGRA) are generally priced higher than skin tests due to lab processing.

Always confirm the current fee directly with the clinic before your appointment.

Key Takeaways

  • TB tests (skin or blood) show if you’ve been infected  not whether you have active disease.
  • Blood tests need one visit; skin tests need two.
  • A positive result needs follow-up testing not immediate panic.
  • For visa purposes only use a government-approved test center.
