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.
Blood urea nitrogen-to-creatinine ratio (BUN:creatinine). The BUN test measures the amount of urea in your blood. Urea is a waste product made when protein is broken down in your body. Urea is made in the liver and passed out of your body in the urine.reatine is broken down into creatinine. Your kidneys take creatinine out of your blood and pass it out of your body in urine. If your kidneys are damaged and can't work as they should, the amount of creatinine in your urine goes down while its level in your blood goes up. Three types of tests can be done.
