LOINC Code
| LOINC code | 88904-8 | ||||
|---|---|---|---|---|---|
| name | Influenza virus A Ag [Presence] in Lower respiratory specimen by Immunofluorescence | ||||
| description | Samples that are positive for influenza virus display fluorescence in the cytoplasmic and/or nucleus. Cytoplasmic staining appears punctate with large inclusions, and nuclear staining is typically uniformly bright. | ||||
| status | ACTIVE | ||||
Fully-Specified Name | |||||
| component | Influenza virus A Ag | ||||
| 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 | Respiratory system specimen.lower | ||||
| scale | Ord = Ordinal: Ordered categorical responses, e.g., 1+, 2+, 3+; positive, negative; reactive, indeterminate, nonreactive. | ||||
| method | IF = Immune Fluorescence: Encompasses DFA, IFA, FA. Usually applies to cells and smears examined microscopically so that both the “where” and the “what” can be assessed, but can also be used on fluids in a way similar to ELISA. Does not include Cell binding assays (see CBA IFA above). | ||||
