The Lui elution technique. A simple and efficient method for eluting ABO antibodies

The Lui elution and the heat elution techniques are the most simple techniques available for eluting antibodies from red cells. Both are very effective for eluting ABO antibodies. We compared the two techniques and found the Lui technique superior in that it more efficiently eluted ABO antibodies, required less hands‐on time, and allowed more flexibility in the procedure. We therefore recommend the Lui elution technique as the method of choice for eluting ABO antibodies, especially for the evaluation of hemolytic disease of the newborn.
