What is a TB Skin Test?
The TB skin test (Mantoux test) is a simple, reliable way to check if you have been exposed to tuberculosis bacteria. A small amount of testing solution (PPD) is injected just under the skin of your forearm. After 48–72 hours, the site is examined by a healthcare professional to see if there is any reaction.
This test does not give you tuberculosis—it only shows whether your body has been exposed in the past.
One-Step vs Two-Step Testing
One-Step Test
- Involves a single injection and one follow-up visit 48–72 hours later.
- Commonly used for one-time screening such as school, work, travel, or immigration requirements.
Two-Step Test
- Recommended for individuals who will undergo regular TB testing (e.g., healthcare workers, long-term care staff, students in medical fields).
- Consists of two separate tests:
- First injection and reading after 48–72 hours.
- Second injection placed 1–3 weeks later, with another reading after 48–72 hours.
- Helps detect “boosted” immune responses from past exposures and establishes a reliable baseline for future annual testing.
Who Should Get Tested?
You may need a TB Skin Test if you are:
✔️ Starting a new job in healthcare, childcare, education, or community services
✔️ Completing school or volunteer requirements
✔️ Applying for immigration or residency programs
✔️ At higher risk of TB exposure (travel, underlying medical conditions, or medication monitoring)
What to Expect During the Test
- Day 1 – Placement
- A small injection of PPD is placed under the skin of your forearm.
- A raised bump (wheal) forms and usually fades within a few hours.
- Day 2–3 – Reading
- You return after 48–72 hours.
- Our healthcare professional measures the swelling (induration) — not the redness.
- Results are interpreted based on your risk factors and history.
- If Positive
- A positive test doesn’t mean you have active TB.
- You may need a chest X-ray or further medical assessment.
- Once positive, repeat skin tests are usually not required.
Important Patient Instructions
- Do not scratch, cover, or apply lotions to the test site.
- You may bathe or shower normally.
- You must return for the reading within 48–72 hours, or the test will be invalid.
- If you miss your reading, the test may need to be repeated.
