Antiphospholipase A2 receptor antibody quantification should be under 20RU/ml normally. Antiphospholipase A2 receptor antibody is a kind of self-targeting antigen, which mainly exists on the surface of podocytes of renal tissues of patients. Positive or quantitative results of this antibody exceeding 20RU/ml usually suggests that the patient has membranous nephropathy, and there is a link between the quantitative results of this antibody and the degree of risk of the patient’s condition in membranous nephropathy. If the result of antiphospholipase A2 receptor antibody is abnormal, patients should improve ultrasound, urine routine, liver and kidney function, urine protein quantitative and other related auxiliary examinations in time to make a clear diagnosis so as to avoid delaying the condition. Antiphospholipase A2 receptor antibody test results should be interpreted by a professional physician, and it is recommended that patients go to the nephrology department of a regular hospital for detailed consultation.
