It consists of a bun sometimes baked, sometimes fried, made from a sweet yeasted dough similar to that used for making doughnuts, split and then filled with raspberry or strawberry jam and cream, most often with a dusting of sugar on the top. 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 the term BUN is still retained by convention. The specimen should not be collected in tubes containing sodium fluoride because the fluoride inhibits urease. Also chloral hydrate and guanethidine have been observed to increase BUN values. The 1886 Jaffé reaction, in which creatinine is treated with an alkaline picrate solution to yield a red complex, is still the basis of most commonly used methods for measuring creatinine. This reaction is nonspecific and subject to interference from many noncreatinine chromogens, including acetone, acetoacetate, pyruvate, ascorbic acid, glucose, cephalosporins, barbiturates, and protein. It is also sensitive to pH and temperature changes. One
