What happens during a tb test?

If it is a skin test, they inject a tiny bubble of fluid under your skin that looks like a mini balloon. If it's a blood test, they just take a tiny vial of blood. Either way, it's over in seconds, so you can reward yourself with a nice cup of chai right after!

I had to undergo both the Mantoux skin test and a chest X-ray during my diagnosis. For the skin test, they inject PPD fluid and you must return in 48-72 hours; do not scratch or cover the spot. If it is a blood test, it is a simple one-time draw, which is much more convenient.

I totally get it, any medical test can make you feel super anxious and nervous. But TB tests are incredibly common and routine, usually just involving a simple blood draw or a tiny scratch on the skin. The lab technicians are very gentle and will make sure you are comfortable.

The test is very simple, either a blood draw or a small skin prick. It won't affect your daily routine, so you can easily do your regular walking or gym sessions. Just avoid heavy rubbing or sweating directly on the arm if you got the skin prick test.

There are two main ways: the IGRA blood test or the Mantoux skin test. The blood test is highly accurate, requires only one lab visit, and isn't affected by past BCG vaccinations. You can easily book a home blood sample collection through most health apps these days.
