What is Burr Cells (Echinocytes)?
Red blood cells with small even bumps around the edge that a lab may see on a blood smear.
Burr cells, also called echinocytes, are red blood cells whose surface shows regular short projections when viewed under the microscope. They are a finding a lab sees on a blood smear rather than a number you can track over time. Their presence can be associated with certain kidney or metabolic conditions, and sometimes they appear simply from how the sample was handled. A lab notes them when reviewing the shape of red blood cells.
