| description | Antibody 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. | |

| component | Blood group antibody | |
| 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 | Ser/Plas Ser = Serum Plas = Plasma | |
| scale | Ord = Ordinal: Ordered categorical responses, e.g., 1+, 2+, 3+; positive, negative; reactive, indeterminate, nonreactive. | |
| method | Blood group antibody screen.PEG | |
