Creatinine

Creatinine is a waste product produced by the body and excreted in the urine. Our laboratory has the capability of determining a quantitative level of creatinine in a urine sample. A normal urine sample has a creatinine level greater than or equal to 20 mg/dL. If no creatinine is present, the sample submitted is not urine. Common substitutes for urine are apple juice and tea.
