Significance of monospecific antisera in the diagnosis and prognosis of autoimmune haemolytic anaemias.

The significance of the monospecific antiglobulin test in the diagnosis and prognosis of autoimmune haemolytic anaemia (AIHA) was tested in 74 patients with AIHA and 59 patients with secondary AIHA. There were 48 female and 26 male patients. Idiopathic AIHA patients more often had two or more positive monospecific reactions in the direct antiglobulin test than secondary AIHA patients.
