  • Immunological method for the detection of malignant tumors and kit for performing the method
    Patent number: 5837474
    Abstract: A method of detecting malignant tumors and determining their mass includes withdrawing fresh blood and/or serum samples from the patient. The blood or serum sample is then stabilized. The tumor determination is obtained from a shift in the ratio of at least one of the IgG subclasses to the sum of the IgG subclasses, relative to the normal ratio in the samples.
