The Urea and Electrolytes test (U and E) is a commonly performed test to assess kidney function. The kidneys are essential for the control of the body's fluid balance. The above tests are used to investigate urinary symptoms and kidney disorders. Urea and creatinine are waste products excreted by the kidneys. Raised levels may indicate kidney damage or disease.
