What does urinary immunoglobulin mean?

Urine immunoglobulin is an indicator in urine routine examination, including IgG, IgM, IgA, etc., mainly used to observe the disease changes, development and prognosis of patients with renal dysfunction, which has very important clinical significance. If the IgA content in urine increases, it indicates that the kidney or urinary tract shows inflammation and infection. It is also necessary to combine white blood cells and pus cells to further select anti-infection treatment. If the IgA content in urine increases, it means that the kidney shows irreversible chronic diseases, such as chronic glomerulonephritis, renal failure, uremia, etc. If IgM is shown in the examination, it means that the condition is serious and the prognosis is quite poor. For the performance of urinary immunoglobulin, it should be treated in time with other examinations, otherwise the function of the kidney continues to deteriorate, which may show irreversible harm.
