Picric Acid test of urine is performed to detect
Answer: B
The picric acid test of urine detects creatinine. In alkaline solution creatinine reacts with picric acid to give an orange-red colour (the Jaffe reaction), which is the basis of the test.
Albumin is tested with heat or acid precipitation, uric acid with the phosphotungstic reagent, and chlorides with silver nitrate, so they are not detected by picric acid. The result is read as an orange colour whose depth is proportional to the creatinine present, and the test is routinely used to measure the amount of creatinine excreted in urine.
