LOINC Code 74038-1: FLUAV H1 RNA NAA+probe (Specimen) [ThreshNum]

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 Influenza virus A H1 RNA. It is commonly used with the system or sample type XXX.

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

• Influenza virus A H1 RNA [Cycle Threshold #] in Specimen by NAA with probe detection
• Influenza virus A H1 RNA
• The quantitative cross/cycle threshold (Ct) value may be reported for real-time PCR-based assays. The value is defined by the number of PCR cycles required for the fluorescent signal of a given product (targeted RNA) to cross the threshold (i.e. exceed background level). In general, the lower the Ct value, the greater the amount of targeted nucleic acid and vice versa. The interpretation (e.g. positive, negative, indeterminate) is determined based on a cut-off value. The submitter's lab reports the interpretation in OBX.8 segment and the specimen type in SPM.4 field of HL7 messaging.
