LOINC Code 75540-5: HAV RNA+Parvovirus B19 DNA NAA+probe Ql (P donor) [Interp]

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 A virus RNA+Parvovirus B19 DNA. It is commonly used with the system or sample type 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 A virus RNA+Parvovirus B19 DNA [Interpretation] in Plasma from Donor Qualitative by NAA with probe detection
• Hepatitis A virus RNA+Parvovirus B19 DNA
• Simultaneously detects hepatitis A virus (HAV) RNA (genotypes 1-3) and parvovirus B19 (B19) DNA (genotypes 1-3) in human donor plasma, either from whole blood (recovered plasma) or collected by apheresis, prior to further manufacture. The aim is to reduce the B19 burden and remove HAV from plasma pools. This term represents the composite result of the individual HAV qualitative test and B19 quantitative test. If either result is reactive, the composite result is reactive; otherwise, it is nonreactive. Plasma may be tested as individual specimens or in pools. Not intended for use on samples of cord blood or as an aid in diagnosis. This term was created for, but is not limited in use to, the cobas TaqScreen DPX test kit.
