PROCEDE D'EXAMEN DE CELLULES POUR LE DIAGNOSTIC D'UNE MALADIE

摘要

A sample of cells from a body under investigation is treated with a radioactively tagged substance which is determined to be selectively absorbed by one or more predetermined cell types sought to be identified either as disease producing cells or abnormal cells of the body and distinguished from other cell types. The radioactively tagged substance is aborbed in different amounts by some cells and rejected by other cells. After treatment and washing, the level of radioactivity of the cell sample is sensed in order to determine from the degree of absorption of the radioactively tagged substance information about the presence of absence of disease. The technique may be applied to mass screening for disease of a particular type or types by collecting and identifying similar samples from many subjects and using a predetermined common standard of radiation level to eliminate those samples which are clearly free from disease.
