D) Commercial tablets

Question

Quizplus · Accepted Answer

A urine specimen for reagent strip glucose analysis can be preserved using refrigeration, boric acid, or commercial tablets containing preservatives. These methods help to prevent the breakdown of glucose in the urine over time, which can affect the accuracy of glucose test results. However, sodium fluoride is not typically used for preserving urine specimens for glucose analysis. While sodium fluoride can be used as an anticoagulant and preservative for other types of laboratory specimens, it is not effective for preserving glucose in urine because it inhibits the action of the enzyme used in most reagent strip glucose tests.
