Normally, person who is suffering with Pulmonary tuberculosis will have their sputum sample checked to confirm the diagnosis along with other clinical manifestations and radigraphs.(x-ray) In the laboratory, the sample will be cultured and put through a technique called Ziehl-Neelsen method. This technique has been used for many years to explore a special character of the TB bacterium that is "Acid-fast bacterium".(AFB). This is identified when the bacterium retains the primary stain(red/pink) which cannot be removed by any decolorizing agent. This is a very specific character of the Mycobacterium species hence applicable to Mycobacterium tuberculi too. So, sputum sample plays a major role for confirming diagnosis in conjunction with other clinical presentation of the victim. Hope, this helps
