If a child is suspected of having tuberculosis (TB), the following investigations may be conducted:
1. Tuberculin skin test (TST): This is a skin test that involves injecting a small amount of tuberculin under the skin of the forearm. A positive reaction indicates exposure to the TB bacteria, but does not necessarily mean the child has active TB disease.
2. Interferon-gamma release assays (IGRA): These blood tests can help determine if a child has been infected with TB bacteria by measuring the immune response to TB proteins.
3. Chest X-ray: This imaging test can help detect abnormalities in the lungs that may be indicative of TB infection or disease.
4. Sputum culture: If the child is able to produce sputum, a sample may be collected and sent to a laboratory to test for the presence of TB bacteria.
5. Chest CT scan: In some cases, a CT scan of the chest may be performed to provide more detailed images of the lungs and any abnormalities that may be present.
6. Bronchoscopy: If necessary, a bronchoscopy may be performed to obtain samples from the lower respiratory tract for testing for TB bacteria.
7. Blood tests: Blood tests may be conducted to assess the child's overall health and check for signs of infection, such as an elevated white blood cell count.
It is important for parents or caregivers to work closely with healthcare providers to determine the appropriate investigations for a child suspected of having TB and to follow the recommended treatment plan.
