A kidney biopsy is a test in which one or more tiny pieces (samples) of your kidney is removed and then looked at with special microscopes. The microscopes make it possible to see the samples in greater detail.
Types of Kidney Biopsy
A biopsy sample can be done in one of two ways:
Percutaneous (through the skin) biopsy: a needle is placed through the skin that lies over the kidney and guided to the right place in the kidney, usually with the help of ultrasound
Open biopsy: the kidney sample is taken directly from the kidney during surgery. The kidney sample is then sent to a pathology lab to check for any signs of disease.
