LOINC Code 74423-5: Enterovirus 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 Enterovirus 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

• Enterovirus RNA [Cycle Threshold #] in Specimen by NAA with probe detection
• Enterovirus 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.
