Method for determination of percentage t cell content of lymphocyte

Abstract From the Canadian patent

A method for determining the percentage T-cell content of lymphocytes, which comprises scanning a test specimen with a pickup device, discriminating a lymphocyte from other cells contained in said specimen from the output level and regional information of the image signals transmitted from said pickup device searching the data marginal to those of the cells discriminated as lymphocytes, to detect pixels corresponding to the image signal output level different from that corresponding to the lymphocytes or background and, discriminating a T-cell from other lymphocytes from the number of detected pixels.
