The function and principle of portable urine analyzer

The portable urine analyzer is used to quickly detect various biochemical indicators and pathological markers in urine to assess human health. It can provide measurement results of urine pH, specific gravity, glucose, protein, ketone bodies, bilirubin, occult blood, nitrite and other indicators. By analyzing these indicators, doctors can help diagnose diseases and monitor patients' treatment effects and disease progression. At the same time, the portable urine analyzer can also perform self-testing in the home environment, helping people understand their health status in real time and the impact of living habits on their health.

The principle of the portable urine analyzer is to use chemical analysis and optical detection technology to conduct urine analysis. It mainly includes the following steps:

1. Collect a urine sample: Use a portable urine collection cup or urine patch to collect the urine sample into the urine analyzer.

2. Sample processing: The analyzer will pre-process urine samples, such as centrifugation, filtration, etc., to remove possible solid particles or impurities.

3. Chemical analysis: Portable urine analyzers have built-in chemical reagents and sensors. Chemical reagents react with specific components in the urine sample to produce chemical reaction products, such as color changes or spectral absorption. The amounts of these chemical reaction products are related to the concentrations of the corresponding components in the urine.

4. Optical detection: Analyzers use optical sensors to determine the concentration of specific components in a urine sample by measuring or detecting color changes or spectral absorption of chemical reaction products. This data is recorded and processed by the analyzer.

5. Data display and interpretation: The portable urine analyzer will display the measurement results on the instrument's screen or send them to a mobile device through a wireless connection. Users can view and interpret urinalysis results through an on-instrument interface or mobile device app.

It should be noted that different portable urine analyzers may use different principles and technologies, but the basic principle is to use chemical reactions and optical detection to analyze the components in urine samples.
