Quizplus · Accepted Answer

Boric acid is commonly used as a preservative for urine specimens for routine urinalysis and culture as it maintains the pH of the urine and inhibits bacterial growth. Sodium fluoride is used to preserve samples for glucose analysis and formalin is a fixative that is only used for tissue samples. Toluene is not used for preserving urine specimens.
