|---|---|---|---|
| name | Influenza virus A H5a RNA [Presence] in Specimen by NAA with probe detection | ||
| description | This code defines a test that identifies the H5 hemagglutinin of influenza A. It is intended for presumptive identification of virus in patients who may be infected with Asian lineage influenza (influenza A subtype A/H5). The specimen can be human respiratory or viral culture. From the CDC: "Testing with the influenza H5a and H5b primer and probe sets should not be performed unless the patient meets the most current U.S. Department of Health and Human Services (DHHS) clinical and epidemiologic criteria for testing suspect A/H5 specimens. The definitive identification of influenza A/H5 (Asian lineage) either directly from patient specimens or from virus cultures requires additional laboratory testing, along with clinical and epidemiological assessment in consultation with national influenza surveillance experts. | ||

Fully-Specified Name | |||
| component | Influenza virus A H5a RNA | ||
| property | PrThr = Present or threshold: The Property PrThr stands for “Presence or Threshold”, meaning either a) the actual presence or absence of an analyte, or b) that the amount of analyte detected is over some predetermined threshold. | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | XXX | ||
| scale | Ord = Ordinal: Ordered categorical responses, e.g., 1+, 2+, 3+; positive, negative; reactive, indeterminate, nonreactive. | ||
| method | Probe.amp.tar | ||

| change reason | The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016. | ||
