The most definitive diagnostic method for active tuberculosis is via sputum culture to identify the acid-fast bacillus.The Mantoux skin test does not distinguish between active infection and past infection.Although a chest x-ray will show characteristic nodules,a sputum culture is the most definitive diagnostic method for active tuberculosis.Unless a patient is septic (infection in the blood),the tuberculosis organism will not be found in the blood.
