LOINC Code


LOINC code73833-6
nameLegionella sp Ab [Presence] in Specimen by Immunofluorescence
descriptionLegionella bacteria in various patient specimens (lung tissues, respiratory tract fluids, and cultures) can be detected by immunofluorescent assays. This codes was created for, but not limited in use to, the submitter's test kit, Zeus Scientific's Legionella DFA Test system. Results are based on the number of typical bacilli observed along with the intensity of bacterial cell wall fluorescence observed. Cultures that are morphologically typical and brightly fluorescent (3+ to 4+) are considered positive.

Fully-Specified Name

componentLegionella sp Ab
propertyPrThr  =  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.
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
scaleOrd  =  Ordinal:  Ordered categorical responses, e.g., 1+, 2+, 3+; positive, negative; reactive, indeterminate, nonreactive.
methodIF  =  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).
