C) Triple phosphate crystals
D) Calcium oxalate crystals

Question

Quizplus · Accepted Answer

A cloudy urine specimen with a pH of 6 is most likely due to the presence of amorphous urates. These are formed by the breakdown of purines, and they are more likely to occur when urine is refrigerated overnight. They appear as small, granular, yellow-brown or reddish-brown particles that can make the urine turbid. Amorphous phosphates are also common in urine, but they typically do not cause turbidity at a pH of 6. Triple phosphate crystals and calcium oxalate crystals can cause turbid urine, but they are typically seen at a pH greater than 7.
