How do you know if a tb test is positive?

A positive TB skin test is determined by a raised, hard bump on your forearm, not just redness. If you are diagnosed, don't worry—you can still maintain a healthy lifestyle and do light walks if your doctor clears you. Just follow the full medical treatment properly.

The nurse will measure the actual induration—the hard, raised area—not just the red skin. If it is positive, keeping your immunity strong with a balanced diet and regular exercise is helpful, but the medical course of antibiotics is the primary thing you must complete.

A positive skin test is indicated by a hard, raised swelling at the injection site after 48 to 72 hours, which a doctor must measure.

In our younger days, TB was a major worry, but today the diagnosis and treatment are extremely straightforward. A positive skin test simply shows a firm swelling of a certain size (usually 5 to 15 mm) after 48-72 hours. Let the doctor measure it; even if positive, it is easily managed with routine medications.

Please don't stress about the bump on your arm. Only a trained healthcare worker can accurately measure it and tell you if it's positive, so wait for your clinic appointment.
