TB Testing

Sputum Containers are sterile, single-use, leak-proof medical devices manufactured from medical-grade polypropylene or polyethylene for the collection, containment, and transport of expectorated lower respiratory tract specimens for diagnostic testing. Essential features include wide-mouth design (50-70 mm) to facilitate direct expectoration without specimen loss or exterior contamination, screw-cap closure with tamper-evident seal, graduated volume markings (30-120 mL), and translucent material permitting visual assessment of specimen quality. Indicated for microbiological culture (bacterial, AFB/tuberculosis, fungal), nucleic acid amplification testing, and cytological examination. Sterility is mandatory to prevent false-positive culture results. Critical safety principles include strict universal precautions due to highly infectious potential (particularly M. tuberculosis), appropriate respiratory protection for collectors, immediate specimen transport with refrigeration for bacterial cultures (≤2 hours), and absolute single-use protocol. An indispensable device in pulmonary medicine, infectious disease, and infection control.
