LOINC Code 74858-2: HEV genotypes 1+2+3+4 RNA NAA+probe Ql (S/P donor)

What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Hepatitis E virus genotypes 1+2+3+4 RNA. It is commonly used with the system or sample type Ser/Plas^Donor.

When is it used?

• Used in lab systems, EHRs, and clinical data exchange.
• May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
• Status: ACTIVE
• Order vs observation: Both
• Method: Probe.amp.tar

What it does not mean

• The code identifies the observation or test, not the actual result.

Key facts

• Hepatitis E virus genotypes 1+2+3+4 RNA [Presence] in Serum or Plasma from Donor by NAA with probe detection
• Hepatitis E virus genotypes 1+2+3+4 RNA
• An in vitro nucleic acid amplification assay for the direct qualitative detection of hepatitis E virus (HEV) genotypes 1-4 RNA in human plasma or serum. This is a blood screening assay to detect HEV RNA. Plasma from whole blood, blood components, or collections by apheresis can also be used. Plasma from all donors or manufacturing pools may be tested as separate specimens or in pools composed of aliquots of individual specimens. This assay is not meant for use on cord blood nor for use as an aid in diagnosis. This term was created for, but not limited in use to, the Cobas® HEV assay.
