[A micromodification of the determination of specific leukocyte lysis in vitro]

A micromodification of the specific leukocyte lysis method was developed; only 0.02 ml of blood is sufficient for the test. The micromodification improved the reproducibility of the technique more than twofold, simplified it, and is recommended for examinations of some populations, including children whose body reactivity is changed and an individual approach to their immunization with TDP vaccine is necessary.
