A kidney biopsy is a medical procedure in which some tissue from the kidneys is cut off to be studied. It is performed to detect kidney diseases or determine the level of developed conditions. A fine needle enters the skin into kidney tissue as the sample is obtained. After that, the sample is analysed under a microscope to detect anomalies like inflammation, infections, or tumours. Kidney biopsies are significant in directing treatment options and estimating the prognosis of different kidney diseases.
