why ascorbic acid in urine?

In the case of patients with high levels of ascorbic acid in the urine, it may be due to consuming a lot of foods with vitamin C content, after being metabolized, it will be excreted in the urine. Therefore, you do not have to worry too much about this problem. Normal readings are 5-10 mg/dL or 0.28-0.56 mmol/L.

Test Details: This two-step enzymatic reaction uses glucose oxidase, peroxidase and a chromogen. Glucose oxidase catalyzes the formation of gluconic acid and hydrogen peroxide via the oxidation of glucose. Peroxidase then catalyzes the reaction of hydrogen peroxide with a chromogen via the oxidation of chromogen to colors ranging between green to gray-blue. Other sugar compounds are not detected.

Test Details: This test is based on the “protein error” of pH indicators on the green color developed from the presence of protein. This dye-binding test is particularly strong with albumin.

Test Details: This test is based on the coupling of bilirubin with diazonium salt in an acidic medium. A pinkish tan color proportional to bilirubin concentration is generated.

Test Details: This test is based on the coupling reaction of urobilinogen with a stable diazonium salt in buffer. A pink to red color proportional to the urobilinogen concentration is generated.

Test Details: This test contains a mixed indicator which assures a marked change in color between pH 5 and pH 9. Colors range from orange through yellow and green to cyan.

Test Details: This pseudo-enzymatic test contains organic peroxide and a chromogen. The peroxidase effect of hemoglobin and myoglobin causes a color change to green.

Test Details: This test is based on Legal’s method in which the test pad contains sodium nitroprusside and glycine in an alkaline medium. A violet color proportional to methylketone is generated.

Test Details: This test is based on modified Griess reaction in which nitrite in the urine reacts with amide to form a diazonium compound. The subsequent coupling reaction yields a pink color in the presence of nitrite. Some Gram positive and non-nitrite-forming bacteria are not detected in this test.

Test Details: This enzymatic test pad contains an indoxyl ester and a diazonium salt. Granulocyte esterases react with indoxyl ester and diazonium salt to generate a violet color.

Test Details: This test is based on Tillman’s reaction in which the presence of ascorbic acid leads to the decolorization of the test pad from gray-blue to orange.
