LOINC code74038-1
nameInfluenza virus A H1 RNA [Cycle Threshold #] in Specimen by NAA with probe detection
descriptionThe 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.

componentInfluenza virus A H1 RNA
propertyThreshNum  =  Threshold Number
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemXXX
scaleQn  =  Quantitative:  The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256
