The Kitchener bun resembles the Berliner, a pastry of German origin – although distinguished from it by an open face and the use
BUN-to-creatinine ratio BUN-to-creatinine ratio In medicine, the BUN-to-creatinine ratio is the ratio of two serum laboratory values, the blood urea nitrogen (BUN) (mg/dL) and serum creatinine (Cr) (mg/dL). Outside the United States, particularly in Canada and Europe, the truncated term urea is used (though it is still the same blood chemical) and the units are different (mmol/L). The units of creatinine are also different (μmol/L), and this value is termed the urea-to-creatinine ratio. The ratio may be used to determine the cause of acute kidney injury or dehydration. The principle behind this ratio is the fact that both urea (BUN) and creatinine
