Although sputum induction is a relatively safe, noninvasive procedure that allows for a direct assessment of cellular and molecular mechanisms that may be used as a diagnostic or monitoring tool, the procedure can be time-consuming and demands standardization in collection, processing, and interpretation of samples; hence, its current application in pediatric asthma is confined to research. All analyses were done separately for each of the laboratory … The reproducibility of cell counts has been reported to be lower if squamous cell contamination represents w20% of all recovered cells [4]. Davis JL, Cattamanchi A, Cuevas LE, Hopewell PC, Steingart KR. Unfortunately, same-day, single-visit tuberculosis diagnosis is not always possible because sputum might not be produced, because of perceptions of superior early morning collection, or because of health system constraints delaying testing and dissemination of results.

A systematic review published in 2015 investigated the effect of two sputum collection methods on indirect markers of sputum quality, but cast doubt on the relevance of these indirect markers for tuberculosis diagnosis.

Most research studied the use of sputum induction or bronchoscopy to improve sputum collection and consequently tuberculosis diagnosis. Methods: We did a systematic review and meta-analysis to investigate whether non-invasive sputum collection methods in people aged at least 12 years improve the diagnostic performance of laboratory testing for pulmonary tuberculosis. All authors participated in the research and preparation of the manuscript, and all have reviewed and approved the manuscript as submitted and take public responsibility for it. eCollection 2020. Epub 2012 Oct 23. Stages at which bias could have been introduced. The key implications of this systematic review and pairwise and network meta-analyses are that non-invasive sputum collection methods involving instruction or pooled sputum collection considerably increase tuberculosis diagnosis and that sputum can be collected at any time, not necessarily in the early morning.

Spot sputum collection refers to rapid, on-demand sputum collection during a single consultation, National data were used in this variable, unless indicated otherwise. Obtaining a specimen involves collecting tissue or fluids for laboratory analysis or near-patient testing, and may be a first step in determining a diagnosis and treatment (Dougherty and Lister, 2015). Proposal for a revision of the case definition of “sputum smear-positive tuberculosis”. In 2007, the case definition of smear positivity changed to include cases with the presence of at least one acid-fast bacillus in at least one sputum sample.
