How long after exposure to tb can you be tested?

Question

My colleague recently tested positive for TB, and I've been in close contact with him. I'm planning to get tested as well. What's the recommended waiting period after exposure to TB before I should get myself tested for the infection?

Sandeep Verma · Accepted Answer

My doctor explained that the immune system takes time to react to the bacteria. You should wait 8 to 10 weeks after exposure to get an accurate TB skin test or blood test, as testing too early can give a false negative.

Don't rush to get tested immediately after exposure because it won't show up. Schedule your test for about 2 months later so you get a reliable result in one go.

Amit Sharma · Answer

Haan, immediately test mat karwana na, positive nahi aayega even if exposed. Wait for about 2 months and then do the proper blood test to be absolutely sure.

Ramesh Deshpande · Answer

Simply wait for 2 to 3 months before getting tested. If you have no symptoms like a persistent cough, there is no need to panic or run for immediate expensive scans.

Suresh Gupta · Answer

Testing early will just mean you have to pay for the test twice. Wait for 8 to 10 weeks so you only pay for one accurate test, and go to a government center where it is done for free or low cost.

I completely understand the anxiety of waiting when you think you've been exposed. But physically, the test needs 8 to 10 weeks to detect the TB response, so try to stay calm and give it time.

Meera Patel · Answer

It is best to wait around 8 to 10 weeks for the test to be accurate, from what I know. Just monitor your health gently and don't panic during this waiting phase.
