If you ask most people outside of Med-Peds, most would say that Med-Peds is a new field. Actually, the initial version of combined Med-Peds training occurred in 1949 in a two year rotating internship. This was replaced by a one year post graduate program.
Your BUN-to-creatinine ratio allows doctors to monitor your kidney health. The BUN-to-creatinine ratio is a routine lab measurement used by your doctor to assess the function of your kidneys. It is calculated by dividing the serum BUN concentration by the serum creatinine concentration. Various conditions affecting your kidneys will alter this ratio in a predictable manner before you even show symptoms. Therefore, it is a useful ratio when monitoring subtle changes in your kidney health.
If your physician orders a BUN test for you, he or she will also likely order a creatinine test. Both tests can indicate how well your kidneys are working. The typical ratio of BUN to creatinine in your blood is 10:1 to 20:1, according to the American Association for Clinical Chemistry.hen your liver filters proteins, it gives off urea nitrogen as a waste product. The kidneys are responsible for filtering the urea nitrogen out of your blood supply and into your urine. If a BUN test reveals higher-than-normal levels, your kidneys may not be working properly or as effectively as they should.
