The interpretation of a Mantoux Test result depends on the size of the induration and the individual's risk factors.
A positive result typically indicates the presence of a delayed-type hypersensitivity reaction to TB antigens, suggesting infection with the TB bacteria.
However, a positive result does not distinguish between latent TB infection and active TB disease.
Further evaluation, such as chest X-ray, medical history, and clinical symptoms, is needed to differentiate between latent TB infection and active disease.
What is an IGRA TB test?
An IGRA (Interferon-Gamma Release Assay) TB test is a blood test used to detect tuberculosis (TB) infection in individuals. It is an important diagnostic tool in the fight against TB, as it provides a more specific and accurate result compared to the traditional Tuberculin Skin Test (TST).
