Today, we are going to learn about the urinary iodine detector, which plays an important role in medical testing, and unveil its mysterious testing principle together.

How important is urine iodine testing?

Iodine is one of the essential trace elements for the human body, playing a crucial role in growth, development, and metabolism. The level of urinary iodine can reflect the intake of iodine in the human body. Urine iodine detection can timely understand the iodine nutritional status of the human body, which is of great significance for the prevention and diagnosis of iodine deficiency and iodine excess related diseases.

The detection principle of urine iodine detector.

The urine iodine detector mainly uses arsenic cerium catalytic spectrophotometry. Specifically, the principle is as follows: in acidic environments, iodine has a catalytic effect on the oxidation-reduction reaction between arsenic acid and cerium sulfate. By utilizing this characteristic, the iodine content in urine samples can be indirectly determined by measuring the concentration changes of residual cerium sulfate in the reaction system.

Firstly, add the urine sample to be tested into a reaction system containing arsenic acid and cerium sulfate. As the reaction progresses, iodine accelerates the rate at which arsenic acid is oxidized by cerium sulfate. After a certain reaction time, measure the concentration of residual cerium sulfate by colorimetric method. Due to the characteristic absorption peak of cerium sulfate at specific wavelengths, its concentration can be accurately measured using a spectrophotometer.

Based on the changes in cerium sulfate concentration before and after the reaction, combined with the standard curve, the iodine content in the urine sample can be calculated. The standard curve is established by measuring a standard solution with a known iodine concentration, which reflects the quantitative relationship between changes in cerium sulfate concentration and iodine content.

In the traditional manual method of detecting urinary iodine, highly corrosive and explosive solutions are used, which have certain risks. Under continuous high-temperature digestion for 2 hours, harmful gases will also be produced to pollute the experimental environment, requiring high time and proficiency.
