What is Mantoux test? | Latent TB | Quantiferon TB Gold test | TB gold | LTBI | Dr.Ankush

The Mantoux test, also known as the tuberculin skin test, is a diagnostic tool used to detect tuberculosis (TB) infection.

It involves injecting a small amount of purified protein derivative (PPD) tuberculin into the skin, usually on the forearm.

After 48 to 72 hours, a healthcare professional checks the injection site for a reaction. A positive reaction, indicated by a raised, red bump, usually indicates TB infection or exposure.

However, it's important to note that a positive Mantoux test doesn't necessarily mean active TB disease; further evaluation is needed to confirm the diagnosis.
