Does tuberculosis screening treat latent tuberculosis infection?

Screening may use a blood test or a skin test to identify an immune response associated with tuberculosis. A positive result does not by itself show whether infection is latent or active. A clinician may arrange a symptom review, examination, and chest imaging, with other tests when needed. Latent infection means tuberculosis germs are present but not causing active illness; treatment is a separate decision intended to reduce the chance of future active disease. Screening cannot remove germs or replace prescribed medicine.

If screening suggests tuberculosis infection, attend the follow-up appointment even if you feel well. Tell the clinician about previous tuberculosis tests or treatment, exposure to someone with tuberculosis, medicines, pregnancy, liver problems, and immune conditions. The care team will decide whether treatment is appropriate, which regimen fits, and what monitoring is needed. Take prescribed treatment exactly as directed and report new symptoms or troublesome effects rather than stopping it independently.

Seek prompt medical care for a persistent cough, fever, night sweats, unintentional weight loss, coughing blood, or worsening weakness after a positive screen or possible exposure. Get urgent help for severe breathing difficulty, chest pain, confusion, or fainting. Follow local advice about contact with others while active tuberculosis is being assessed.

Ask which test was used, what the result means, how active disease will be excluded, whether preventive treatment is suitable, and what monitoring or contact advice applies.
