Part Description

LP14400-3   Hepatitis C virus
Hepatitis C virus (HCV) is a small (50 nm in size), enveloped, single-stranded, positive sense RNA virus in the genus hepacivirus, which is in the Flaviviridae family. More than 170 million people worldwide are affected by hepatitis C, and the majority of patients with acute hepatitis C develop chronic HCV infection, which can result in liver cirrhosis, hepatic failure or hepatocellular carcinoma. The HCV core protein is a highly basic, RNA-binding protein that forms the viral capsid. The E1 and E2 envelope glycoproteins are necessary for viral entry and fusion. Non-structural proteins include NS2, NS3, NS4A and 4B, and NS5A and 5B. The NS2-NS3 complex functions as a protease, and NS3 also has a helicase/NTPase domain. NS4A is a cofactor of NS3 protease activity. NS3-NS4A protease is one target of anti-HCV drugs. NS4B is a membrane anchor for the replication complex, and NS5A plays a role in regulating viral replication. NS5B is an RNA-dependent RNA polymerase.

Change Reason
The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.; The EIA method, which was always intended to cover more than just enzyme-linked immunoassay and whose display name for the long common name has always been Immunoassay, was renamed IA in order to eliminate ambiguity about whether the method has a broader meaning than just enzyme-linked immunoassay. Likewise, EIA.rapid was renamed IA.rapid. These changes were approved by the Laboratory LOINC Committee in June 2016.
