  • Publication number: 20200271647
    Abstract: A kit for diagnosing a renal disease or predicting prognosis of the renal disease from urine includes a binding molecule specifically bound to cMet protein contained in the urine. When a level of cMet protein in urine is higher than a normal group, this condition is diagnosed as the renal disease or predicted to have poor prognosis thereof. A screening method of a substance for treatment of renal disease includes first-measuring a level of cMet protein in urine of an object, injecting a sample to be analyzed into the object, and second-measuring the level of cMet protein in urine of the object. When the level of cMet protein in the second-measuring is lower than the level of cMet protein in the first-measuring, the sample to be analyzed is the substance for treatment of renal disease.
