§493.1240 Condition: Preanalytic systems
Each laboratory that performs nonwaived testing must meet the applicable
preanalytic system(s) requirements in §§493.1241 and 493.1242, unless HHS
approves a procedure, specified in Appendix C of the State Operations Manual
(CMS Pub. 7), that provides equivalent quality testing. The laboratory must
monitor and evaluate the overall quality of the preanalytic systems and correct
identified problems as specified in §493.1249 for each specialty and subspecialty of
testing performed.
Interpretive Guidelines §493.1240
Preanalytic refers to all steps taken prior to the actual testing of a patient specimen from
the test request to the actual testing of the specimen. The preanalytic systems
requirements fall into three distinct standards: test requests; specimen submission,
handling, and referral; and preanalytic systems quality assessment.
Significant deficiencies cited under this condition may indicate deficiencies under
personnel responsibilities. Use D5300 when deficiencies are identified that have the
potential to, or are adversely affecting patient testing, or when they are systemic and
pervasive throughout the laboratory, and are not limited to any one specialty or
subspecialty.
To determine which tests are categorized as waived or nonwaived testing (i.e., moderate
and high complexity tests), refer to the following web link for the FDA categorization
database
(http://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfCLIA/Search.cfm?sAN=0). Test
systems, assays and examinations not included in this listing (i.e., not yet categorized) are
considered high complexity.
