We have 1 antibody panel and the only type of Antibody ID we perform is a modified Antibody ID (1 rule out) for maternal anti-D when we have documentation that the patient received RhIG during the pregnancy. We have an inspector asking what we do for proficiency for this tsting. We subscribe to API for our proficiency but they only offer a general ABID proficiency. Can anyone share how they handle proficiency for this selective type of Antibody ID testing?
