The Renal Biopsy

One of the questions that we hear most often is, “How do I know if my patient’s biopsy tissue is a good sample?” To that end, Dr. Walker wrote a paper (published in the February 2009 issue of Archives of Pathology Laboratory Medicine), discussing current practices for renal biopsy. The objective was to provide an overview of the renal biopsy, including the techniques and its complications, and to summarize proper laboratory methods for processing renal biopsy tissue.
