LOINC Code 75265-9: Blood group antibody screen PEG method Ql

What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Blood group antibody. It is commonly used with the system or sample type Ser/Plas.

When is it used?

• Used in lab systems, EHRs, and clinical data exchange.
• May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
• Status: ACTIVE
• Order vs observation: Both
• Method: Blood group antibody screen.PEG

What it does not mean

• The code identifies the observation or test, not the actual result.

Key facts

• Blood group antibody screen [Presence] in Serum or Plasma by Polyethylene glycol (PEG) method
• Blood group antibody
• 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.
