  • Title: Fate of sputum samples transported in bottles containing cetylpyridinium chloride and sodium chloride: a national reference laboratory study.
    Author: Visalakshi P, Meharwal SK, Arora J, Bhalla M, Singh N, Myneedu VP, Behera D.
    Journal: Indian J Tuberc; 2012 Apr; 59(2):112-5. PubMed ID: 22838211.
    Abstract:
    The transportation of sputum samples may sometimes take more than one week which results in an increased contamination rate and loss of positive cultures. The current study was planned to analyze the recovery rate of mycobacteria from transported samples with and without Cetylpyridinium chloride (CPC). Addition of CPC is useful for isolation of M. tuberculosis from sputum subjected to long-term storage.
