24363-4

LOINC code 24363-4 identifies "Acute hepatitis 2000 panel - Serum". The LOINC Acute hepatitis panel 2000 was created based on the panel of tests recommended for diagnosing viral hepatitis in the year 2000 by the Health Care Financing Administration (HCFA), which is now known as the Centers for Medicare & Medicaid Services (CMS). The panel corresponds to the American Medical Association's CPT code 80074. The HCFA panel includes IgM testing for Hepatitis A and B as well as Hepatitis B surface antigen and Hepatitis C antibody, but does not specify exactly how results should be reported (e.g., qualitative versus quantitative). In 2018 we reviewed how several major laboratories report results for this panel and which LOINCs they use, and found that the Hepatitis A and B codes contained in this panel are used consistently across laboratories, but that several laboratories are using [LOINC: 48159-8] to report a quantitative result for Hepatitis C antibody in addition to or instead of the ordinal Hepatitis C antibody code [LOINC: 13955-0]. In order to accommodate these labs, we added 48159-8 to the panel for the December 2018 LOINC release.

This code measures Acute hepatitis 2000 panel in Ser. It belongs to the PANEL.MICRO class in the LOINC classification.

LOINC (Logical Observation Identifiers Names and Codes) is a universal standard for identifying laboratory and clinical observations. It is maintained by the Regenstrief Institute and used worldwide for health data exchange.
