What Is a TB Skin Test (TST / Mantoux)?

A tuberculosis skin test — formally called the Tuberculin Skin Test (TST) or Mantoux test — checks whether your immune system has been exposed to Mycobacterium tuberculosis, the bacterium that causes TB. According to the CDC, TB testing is required in many healthcare, childcare, school, and food service settings because TB can spread through the air and many infected people have no symptoms. Testing identifies latent TB infection — where the bacteria are present but not yet causing illness — so treatment can prevent it from becoming active.

The test itself is simple: a small amount of purified protein derivative (PPD) is injected just under the skin of the forearm. You return 48 to 72 hours later for a nurse to measure any reaction (induration — a raised, firm bump, not just redness). We document and interpret the result and provide a signed form or certificate for your employer or school.

Who Needs a TB Skin Test?

• Healthcare workers — required for employment and annually in most settings
• Nursing and allied health students — required before clinical placements
• Childcare and school employees
• Food service workers
• Correctional facility staff
• Anyone with recent travel to countries with high TB rates
• Anyone with recent close contact with a known TB patient
• Certain visa or immigration requirements
• People with HIV or weakened immunity — more susceptible to TB reactivation

What to Expect During Your TB Skin Test Visit in Sanford, FL

1. Day 1 (placement visit) — a small amount of PPD solution is injected intradermally into the inner forearm. You feel a brief sting and a small bubble forms under the skin. The visit takes under 5 minutes.
2. 48–72 hours later (reading visit) — a provider measures the induration (firmness, not just redness) at the injection site in millimeters. This must be done within the 48 to 72 hour window — after 72 hours, the test is invalid.
3. Result interpretation — what counts as positive depends on your risk category. Mayo Clinic and NIH guidelines define the cutoffs for each risk group.
4. Documentation — a signed, stamped result letter suitable for employer, school, or program requirements.
5. Follow-up if positive — a positive TST does not mean active TB. A chest X-ray and clinical evaluation determine whether latent or active infection is present, and whether treatment is needed. We coordinate this process. Harvard Health explains the difference between latent and active TB and the treatment approach.

QuantiFERON Blood Test (IGRA) — An Alternative to the Skin Test

Some employers and schools now accept or prefer the QuantiFERON-TB Gold (IGRA) blood test instead of the skin test. IGRA has several advantages: it requires only one visit, is not affected by prior BCG vaccination, and is more specific. Ask us at your visit if IGRA is an option for your requirement and whether we can order it on-site or refer you for the blood draw.

Frequently Asked Questions About TB Skin Tests in Sanford, FL

Does the TB skin test hurt?

Minimally. The intradermal injection stings briefly and leaves a small bump that fades within a few hours. Most patients find it less uncomfortable than a regular injection.

What if I had the BCG vaccine?

BCG vaccination (common outside the US) can cause a false positive TST reaction. This is one reason IGRA blood tests are often preferred for people vaccinated with BCG. Tell us your vaccination history at the visit.

I missed my 72-hour reading window. What do I do?

The test cannot be read after 72 hours and must be repeated with a new placement. Come in as close to 48 hours as possible and no later than 72 hours after placement.

Can I shower or swim after the test?

Yes — water will not affect the result. Avoid rubbing or scratching the site.

What is the cost?

TB skin test pricing covers both the placement and reading visits. Call 321-363-3384 for our current rate or check our accepted insurance list. Many insurance plans cover TB testing for occupational requirements.

Can I get tested and have results on the same day?

No — the TST requires 48 to 72 hours for the immune reaction to develop. If you need same-day results, ask about the IGRA blood test option.
