Laboratory Compliance Information


Disease Reporting Rules

  • "Licensed laboratories shall report to the Department of Human Services (DHS), on a quarterly basis beginning March 1, 2007, a summary of the number of individuals tested and the number with HIV-positive test results". The definitive ruling for ELR labs has not yet been made, but the interim recommendation is to keep a log of tests including the specified variables: test type, pos/neg result, gender, age group.
  • As of June 2006, labs are asked to report results of all viral loads and CD4 counts (regardless of result or HIV status of the patient) and results of all tests that are indicative of and specific for HIV (these include positive Western Blot assays, positive p24 antigen tests, and positive viral cultures).
  • As of July 2007, labs are asked to report mumps-specific positive tests (e.g., IgM, virus isolation, PCR) within one working day.

  • Logical Observation Identifier Names and Codes (LOINC®) for specific laboratory procedure names
  • Systematized Nomenclature for Human and Veterinary Medicine (SNOMED®) for descriptions of findings, specifically for organism names
  • Code Verification List: List of test codes, to be completed by testing labs (231K)
