[Autolymphocytotoxins in the differential immunodiagnosis of chronic lympholeukemia and malignant non-Hodgkin's lymphoma at the leukemization stage].

The authors have investigated the possibility of using sera with cold auto-lymphocytotoxic antibodies for the differential diagnosis of chronic lymphocytic leukemia (CLL) and malignant non-Hodgkin's disease (MNHD) at the stage of leukemization. The new rapid immunologic method was approved in the diagnosis of 40 CLL and 52 MNHD patients. The high informative value of this method has permitted the authors to recommend its use as an additional procedure for the differential diagnosis of the above lympho-proliferative diseases.
