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 Foot and mouth disease virus 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

Foot and mouth disease virus RNA [Units/volume] (viral load) in Specimen by NAA with probe detection
Foot and mouth disease virus RNA
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 includedThe 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).
