56024-3

LOINC code 56024-3 identifies "Influenza virus A N1 RNA [Units/volume] (viral load) in Specimen by NAA with probe detection". The values are the number of PCR cycles and are typically reported out as "Ct value" (cycle threshold). If the number of cycles permitted by the procedure are exceeded prior to the threshold being reached, the value is reported out as zero (0). If the threshold is reached prior to the maximum number of cycles, the number of cycles taken to reach the threshold is reported ( e.g. 1-40). A graph representing the threshold and the Ct curve is included: The yellow line is the negative control (never reaches the threshold) and the colored lines are all "positive", reaching the threshold at different number of cycles (i.e. 19.5 to 24.1).

This code measures Influenza virus A N1 RNA in XXX. It belongs to the MICRO class in the LOINC classification.

LOINC (Logical Observation Identifiers Names and Codes) is a universal standard for identifying laboratory and clinical observations. It is maintained by the Regenstrief Institute and used worldwide for health data exchange.
