Monitoring of quality indicators is an essential component of quality assurance for the Cartridge-based Nucleic Acid Amplification Test (CBNAAT).<\/p>\n\n

Routine monitoring of quality (performance) indicators:\n\t
1. Critical element of quality assurance for any diagnostic test <\/li>\n\t\t
2. International Organisation of Standardisation (ISO) requirement<\/li>\n\t<\/ol>\n\t<\/li>\n\t
3. Each testing site should collect and analyze quality indicators monthly.<\/li>\n\t
4. Document and investigate any unexplained change in quality indicators, such as:\n\t
  1. Increase in error rates<\/li>\n\t\t
  2. Change in Mycobacterium tuberculosis<\/em> (MTB) positivity rate or Rifampicin (Rif) resistance rate<\/li>\n\t\t
  3. Significant change in volume of tests conducted<\/li>\n\t\t
  4. Error rates > pre-determined threshold (>5%)<\/li>\n\t\t
  5. Test turnaround time<\/li>\n\t<\/ol>\n\t<\/li>\n\t
  6. All unexpected trends should be reviewed by the laboratory manager and linked to corrective actions.<\/li>\n\t
  7. Standard set of quality indicators should be used for all CBNAAT testing sites.<\/li>\n\t
  8. System should be in place for centralized reporting of monthly quality indicators.<\/li>\n<\/ul>\n"},"subContentId":"cf5f32ba-4d77-4518-9bd8-dea0c4ba33e2","metadata":{"contentType":"Text","license":"U","title":"Untitled Text"}},"alwaysDisplayComments":false,"backgroundOpacity":0,"displayAsButton":false,"buttonSize":"big","goToSlideType":"specified","invisible":false,"solution":""}],"slideBackgroundSelector":{}},{"elements":[{"x":2.178649237472767,"y":2.159827213822894,"width":51.19825708061002,"height":92.87257019438445,"action":{"library":"H5P.AdvancedText 1.1","params":{"text":"
