Qualitative detection of HIV-1 RNA and hepatitis C virus (HCV) RNA from volunteer donors of whole blood and blood components, screen of live organ donors, and test blood specimens to screen cadaveric donors. HBV screening of individual samples and pooled samples. 10/3/2006: Gen-Probe San Diego, CA US Licence 1592 Chiron Corporation
There are several diagnostic tests for hepatitis C, including HCV antibody enzyme immunoassay (ELISA), recombinant immunoblot assay, and quantitative HCV RNA polymerase chain reaction (PCR). [16] HCV RNA can be detected by PCR typically one to two weeks after infection. In contrast, antibodies can take substantially longer to form and thus be ...
This alternate mechanism relies on the direct binding of the 40S ribosomal subunit by the internal ribosome entry site (IRES) in the 5' UTR of HCV RNA. The HCV IRES adopts a complex structure, and may differ significantly from IRES elements identified in picornaviruses. A small number of eukaryotic mRNAs has been shown to be translated by ...

HCV genome. Nonstructural protein 5B (NS5B) is a viral protein found in the hepatitis C virus (HCV). [1] It is an RNA-dependent RNA polymerase, having the key function of replicating HCV's viral RNA by using the viral positive RNA strand as a template to catalyze the polymerization of ribonucleoside triphosphates (rNTP) during RNA replication.
The complexity of the HCV genotypes made the treatment specific for the associated genotype. The treatment for the HCV genotype also depends on the presence or absence of cirrhosis. [11] There are six major genotypes of hepatitis C virus which includes many subtypes. [12] The genotype can affect treatment of HCV infections. [3]
A test panel is a predetermined group of medical tests used in the diagnosis and treatment of disease.. Test panels (sometimes called profiles) are typically composed of individual laboratory tests which are related in some way: by the medical condition they are intended to help diagnose (cardiac risk panel), by the specimen type (complete blood count, CBC), by the tests most frequently ...
Tests selected to screen donor blood and tissue must provide a high degree of confidence that HIV will be detected if present (that is, a high sensitivity is required). A combination of antibody, antigen and nucleic acid tests are used by blood banks in Western countries.
