LOINC Code 73693-4: African swine fever virus DNA NAA+probe (Tiss) [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 African swine fever virus DNA. It is commonly used with the system or sample type Tiss.

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

• African swine fever virus DNA [Cycle Threshold #] in Tissue by NAA with probe detection
• African swine fever virus DNA
• 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 DNA) 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 of HL7 messaging.
