Diagnostic tests include tuberculin skin testing, sputum smear microscopy, chest radiography and nucleic acid amplification. Treatment involves a combination of first-line antibiotics like isoniazid, rifampin and pyrazinamide over 6-9 months. Management also includes measures like proper nutrition and avoiding tobacco and alcohol to aid treatment. Drug-resistant TB like multi-drug resistant TB poses challenges and requires utilizing second-line drugs. The desired outcomes of TB treatment are rapid identification, appropriate treatment, resolution of symptoms and adherence to cure the infection
