Mantoux Tuberculin Skin Test (5TU)

The "Mantoux test Tuberculin test (5TU)" is a crucial diagnostic tool with dual clinical utility for tuberculosis (TB) screening and diagnosis. Administering an intradermal injection of purified protein derivative (PPD) tuberculin with a strength of 5 Tuberculin Units (5TU), this test evaluates the induration (swelling) at the injection site after 48 to 72 hours. It plays a vital role in identifying individuals at risk of TB exposure and aiding in the diagnosis of latent TB infection or active TB disease. Positive results indicate a delayed hypersensitivity response to PPD tuberculin, suggesting the presence of latent TB or active TB, prompting further evaluation for appropriate management strategies. Though a positive Mantoux test alone does not confirm active TB, it complements other clinical and radiological findings in making a definitive diagnosis. Overall, the Mantoux test Tuberculin test (5TU) significantly contributes to TB control efforts, guiding preventive treatment for latent TB and timely initiation of therapy for active TB cases, thus improving patient care and public health outcomes.
