Uric acid

A bodily waste product excreted through the kidneys. When the body produces too much uric acid, or doesn’t excrete it efficiently, excess uric acid can deposit as crystals in the joint and other tissues – a condition known as gout.


The analysis of urine using physical, chemical or microscopic tests to detect the presence of bacteria that could be causing an infection, levels of uric acid excreted to monitor gout, or abnormal constituents, such as glucose or protein in the urine, which could signify a condition such as diabetes.
