Double negative alpha/beta T cell panel

This test measures the percentage of CD3 positive alpha/beta T cells which negative for both CD4 and CD8. These cells are raised in frequency in Autoimmune Lymphoproliferative Syndrome (ALPS). ALPS is a rare disorder of lymphocyte apoptosis associated with autoimmunity and lymphoproliferation. Idiopathic thrombocytopenia purpura (ITP) and autoimmune haemolytic anaemia (AIHA) are common autoimmune phenomena in these patients.
