Abstract

Dear Sir,
Warm autoimmune haemolytic anaemia (WAIHA) is the most common type of AIHA (65-70%) and is mostly associated with the presence of immunoglobulin (Ig) G on red blood cells (RBCs)1. Individuals with WAIHA typically present with symptoms of anaemia, and some severe cases require chronic blood transfusion. However, in AIHA, precise serological phenotyping is not always possible since antihuman-globulin (AHG)-reacting antisera are not suitable for patients with a positive direct antiglobulin test (DAT)1.
