waxy cast
Which of the following characteristics best differentiates
waxy casts from fibers that may contaminate urine sediment?
Waxy casts do not polarize light; fibers do.
The bilirubin reagent strip and tablet tests are based on
the coupling of bilirubin with a diazonium salt.
The glucose specificity of the double sequential enzyme reaction used on reagent strip tests is due to the use of
glucose oxidase.
