Apparatus for measuring lymphocyte subclasses |
摘要 |
A blood sample is prepared by combining a fluorescently tagged monoclonal antibody with blood cells. The sample is then passed through a flow cytometer and light scattered by each blood cell in two directions is sensed simultaneously by a single sensor. Lymphocytes are discriminated from other cells by using an intensity distribution of the total scattered light. Then, by using a distribution of fluorescent light intensity of each cell thus discriminated, the cells in a lymphocyte subclass of interest are enumerated with a high accuracy. The data acquired are utilized in diagnosing immunological incompetence or the like.
