module 8 Clinical Laboratory Regulations and Accreditation

Vocabulary terms covering regulatory standards under CLIA, complexity scoring criteria, proficiency testing requirements, and voluntary accrediting agencies (TJC, CAP, COLA).

Clinical Laboratory Improvement Amendments of 1988 (CLIA)

Federal legislation passed in $1988$ to regulate laboratory testing due to real and perceived problems; it supersedes all other laboratory regulations and categorizes tests based on complexity.

OSHA and HIPPA

Two well-known regulatory agencies that regulate aspects of laboratory testing in addition to CLIA.

Centers for Medicare & Medicaid Services (CMS)

The agency that provides the downloadable version of CLIA regulations on its website, maintains the list of waived tests, and receives Proficiency Testing (PT) results for oversight.

CLIA Complexity Categories

The three divisions of laboratory testing under CLIA: Waived, Moderate Complexity (which includes Provider Performed Microscopy), and High Complexity.

Provider Performed Microscopy

A specific testing subcategory included under Moderate Complexity testing within the CLIA framework.

Seven Criteria for CLIA Test Complexity

The criteria scored $1$, $2$, or $3$ to evaluate complexity: knowledge; training and experience; reagents and materials preparation; characteristics of operational steps; calibration, quality control, and proficiency testing materials; test system troubleshooting and equipment; and interpretation and judgment.

Moderate Complexity Testing

Test systems or methodologies that receive a total cumulative score of $12$ or less when evaluated across the seven CLIA complexity criteria.

High Complexity Testing

Test systems or methodologies that receive a total cumulative score above $12$ when applying scores across the seven CLIA complexity criteria.

Waived Testing

Test methods that receive a score of $1$ on complexity criteria and are waived from regulatory oversight, requiring no specific Quality Control or Quality Assurance demands beyond following manufacturer directions.

Criteria for CLIA Waived Tests

Tests cleared by the FDA for home use (e.g., pregnancy tests, glucometer testing) or healthcare tests using simple and accurate methods that reduce erroneous result risks to negligible (e.g., Rapid Strep Testing). Currently includes $> 100$ tests.

Proficiency Testing (PT)

The process of receiving unknown samples from external organizations (e.g., CAP, API), analyzing them like patient samples, and returning results to assess internal quality for CLIA-regulated analytes in moderate and high complexity testing.

Proficiency Testing (PT) Failure Sanctions

Regulatory consequences triggered by failing PT for the same analyte in two of three consecutive testing events, ranging from submitting a plan of corrective action to mandatory suspension of testing for that analyte.

The Joint Commission (TJC)

A voluntary organization that accredits $> 80\%$ of U.S. healthcare organizations, inspects participating laboratories every $2$ years, enforces specific QC and training requirements, and inspects waived testing.

College of American Pathologists (CAP)

An organization that provides accreditation exclusively to laboratories using detailed checklists with standards more stringent than CLIA, placing major importance on proficiency testing.

Commission on Laboratory Accreditation (COLA)

An accrediting organization originally established to accredit physician office laboratories (POLs) that now also accredits other testing facilities, including small hospitals.
