|Case Study Four|
A 72 year old male with a previous history of a cold antibody is in the ICU with an abdominal aortic aneurysm. The doctor has ordered 8 units of packed red cells to be crossmatched at all times for this patient.The patient's ABO/Rh is B positive.The current antibody screen is positive in both the immediate spin phase and the AHG phase.Anagram resultsResults of the anagram show the presence of an antibody that reacts at immediate spin and AHG. Because Screen cell 1 is negative at the IS phase and positive at AHG, there are possibly multiple antibodies present (IgM and IgG).Antibody PanelSelected Cell Panel 1Enzyme PanelSelected Cell Panel 2
|Case Study Four- Antibody Panel|
Antibody panel resultsResults of the antibody panel show reactions at immediate spin and AHG with varying strengths. The pattern at IS matches P1. Remember that varied strengths can mean multiple antibodies, dosage or both.There are not enough rule-out cells to rule anything out with 3 negative reactions. You can use panel cells that reacted at IS and are negative at AHG for rule-out. Use cells 4 and 10 for rule-outs. Antibodies that have no rule-outs from this panel are: C, E, Cw, Kpa, Jsa, Fya, Lea, M,s, P1, and Lua. Cw, Kpa, Jsa, and Lua are usually not present on panels and fall under the "unable to rule out" catagory. C,E, Fya and s are clinically siginificant and should have further testing done to rule-out or rule-in these antibodies. Lea , P1 and M tend to react at IS, so if the pattern of reactivity is compared to the reaction pattern at IS, there is a match for P1.A selected cell panel was then performed.
