Radiosensitivity testing


  • colony survival assay


Testing specific to ataxia-telangiectasia (A-T) and other disorders in which cells are particularly sensitive to ionizing radiation; demonstrates colony formation of a blood lymphocyte cell line following irradiation, which is abnormal in approximately 99% of patients with clinically diagnosed A-T, though the sensitivity of such testing in light of a suspected but unsure diagnosis of A-T has not yet been documented
