The analysis of anti-glomerular basement membrane antibodies (Anti Glomerular Basement Membrane, GBM) is a laboratory test used to detect the presence of antibodies in the blood that react with the basement membrane in the kidneys. This test is essential for diagnosing certain autoimmune disorders, such as autoimmune glomerulonephritis, which can lead to kidney failure. It helps doctors identify the causes of symptoms related to kidney function and guide appropriate treatment plans based on the results.
