Dr. Irwin Abraham answered

Specializes in Sports Medicine

Means normal kidneys: BUN (blood urea nitrogen) is a test for a number of certain chemicals in the blood. Creatinine is a specific chemical that is released from the muscles. These are filtered out by the kidneys into the urine. The ratio of 18 means 18 to 1 of BUN to creatinine ; it is normal. If the ratio is higher that means the circulation is not delivering blood fast enough to the kidneys. If the ratio lowers to 1.
