About this test

The Mantoux (tuberculin skin) test checks whether your body has been exposed to TB germs. A small amount of tuberculin is injected under the skin of the forearm, and the swelling is measured after 48–72 hours.

Why is this test done?

  • Screen for TB infection, especially in children
  • Check contacts of TB patients
  • Screen before treatment that lowers immunity

Symptoms — when should you get tested?

  • Contact with a TB patient
  • Long cough or fever in a child
  • Poor weight gain

Normal range

Induration < 10 mm

Reference ranges differ slightly between labs, methods, age and sex. Always discuss your report with your doctor.

If your result is high

A swelling of 10 mm or more is usually positive and means TB infection is likely (5 mm in people with HIV or weak immunity). It does not tell active from latent TB.

Common reasons
  • Latent or active TB
  • Past BCG vaccination (can cause mild positive)
  • Other mycobacteria
