| Summary: | In this paper we present the data of lymphocyte radiosensitivity testing used for characterization of radiosensitive cellular phenotype and diagnostics of ataxia-telangiectasia disease. We point out the advantage of lymphocyte micronucleus test (CBMN) over other cellular tests for assessment of radiosensitivity: the first advantage of CBMN is that primary patient cells are used (less than 1 ml), the second one is that the results of testing are obtained within 3 days and there is no need for establishing a patient-derived cell line, which requires additional time and application of more expensive methods. The third advantage of CBMN method is that it gives information about proliferative ability of cells, which can recognize dysfunctional ataxia-telangiectasia mutated protein. The results are fast and accurate in diagnostics of ataxia-telagiectasia diseases.
