  CLIA Regulated Analytes




Updated June 4, 2010

Participation in proficiency testing is required for analytes listed in the CLIA’ 88 regulation and analyzed by non-waived methods. As such, these analytes require enrollment in a Centers for Medicare and Medicaid Services (CMS) approved proficiency testing (PT) program. The frequency for this required PT is five challenges three times per year (exception is Mycobacteriology which requires five challenges two times per year). Following is a list of the analytes regulated by CMS.

  • Bacterial Antigen Detection
  • Bacterial Identification (aerobic/anaerobic from various sources)
  • Gram Stain


  • Acid Fast Smears/Culture/ID/Antimycobacterial Susceptibility Testing
  • Isolation and identification of mycobacteria by culture


  • Culture for Yeast or Fungal ID at genus or species level


  • Parasite identification (wet mount, concentration and/or permenant stain, immunoassay)


  • Virus Detection (by culture or antigen testing)

For all other 'non-regulated' analytes, CLIA dictates that the laboratory must have a quality assurance plan that establishes the accuracy and reliability of the testing at least twice per year. The CAP Surveys and EXCEL proficiency testing programs offer a wide array of products to conveniently assist laboratories in fulfilling this requirement. It is also important for laboratories to check with their state and other accrediting agencies they may use as they may mandate additional requirements.
