nameBlood group antibody screen [Presence] in Serum or Plasma by Polyethylene glycol (PEG) method
descriptionAntibody screening is used to demonstrate unexpected antibodies (other than ABO) and is performed on both donors and recipients to help ensure compatibility between recipient antibodies and donor red cells. Polyethylene glycol (PEG) is a blood bank agent that reduces antibody screening incubation time by excluding water and therefore allowing red cells to come closer together during centrifugation. PEG may enhance the expression of warm antibodies and auto-antibodies. A downside to PEG is that use may lead to false positive reactions at 37C from nonspecific agglutination. An advantage of PEG use is that it may provide greater sensitivity than LISS or albumin.

Fully-Specified Name

componentBlood group antibody screen
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.
systemSer/Plas
    Ser  =  Serum
    Plas  =  Plasma
scaleOrd  =  Ordinal:  Ordered categorical responses, e.g., 1+, 2+, 3+; positive, negative; reactive, indeterminate, nonreactive.

Associated Observations

LOINC codes that represent optional associated observation(s) for a clinical observation or laboratory test. A LOINC term may represent a single associated observation or panel containing several associated observations.

History/Usage

last updated2.56
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.
