Streptococcus pyogenes Ag [Presence] in Throat by Immunofluorescence   6557-3

LOINC Code


LOINC code6557-3
nameStreptococcus pyogenes Ag [Presence] in Throat by Immunofluorescence
statusACTIVE

Fully-Specified Name

componentStreptococcus pyogenes Ag
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.
systemThrt  =  Throat
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).

History/Usage

test rank10203 of 2000 most commonly performed tests by labs in USA
first released
last updated2.73
last change typeMIN  - change to field other than name
change reasonThe 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.
