I've been wondering if it's a good idea to get tested for TB every year to catch it early. Also, is it possible to have active TB without showing any symptoms?

The most common test for TB is the Mantoux tuberculin skin test or the TB blood test. Early detection can help in timely treatment and prevent the spread of the disease. Is it possible to have active TB without any symptom? Yes, it is possible to have active TB without any symptoms. This is known as latent TB infection, where the bacteria are present in the body but are not causing any symptoms. In such cases, treatment may still be necessary to prevent the infection from progressing to active TB disease.
