Amorphous urates in urine are typically found in which pH and what happens to them when heated?

Amorphous urates form in acidic urine because low pH causes urate salts to precipitate as fine granular material. A helpful clue is that these precipitates dissolve when the sample is warmed; heating increases the solubility of urates, so the amorphous granules disappear. This pattern—occurring in acidic urine and dissolving upon heating—is what makes this the best description. They’re not linked to pregnancy, and the key diagnostic feature is their dissolution with heat, not persistence at all temperatures.
