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.
Other conditions that cause BUN-to-creatinine ratio to rise are kidney disease, kidney stones, or bleeding in the intestines. Low BUN-to-creatinine can occur in pregnancy, liver disease, or a diet low in protein. The BUN-to-creatinine ratio is not a precise or reliable test, though.f kidney function begins to decline, BUN and creatinine rise. A normal creatinine depends on muscle mass and age. In general, a normal creatine is 0.5 to 1.2 milligrams per deciliter (mg/dL). A normal BUN is 7 to 20 mg/dL.
