Urine Analyzer Machine: How Technology is Transforming Urine Testing

In fields such as hospitals and laboratories, the chemical composition of urine is often measured to determine whether there are any issues with the urinary system, liver, or other organs. The urine analyzer machine represents a major breakthrough in the history of medicine, bringing significant convenience to health diagnosis and treatment. This device is designed to quickly and accurately analyze urine samples. Through automated processes, it reduces human error, improves efficiency, and enables more comprehensive analysis. In this article, we will explore the working principles of urine analyzers, the tests they perform, and product recommendations.

What are the parts of a physical analysis of urine

1. 8-11 item screening combination urine test strips for use in initial diagnosis and health checkups.

   The 8 test items include: protein, glucose, pH, ketones, bilirubin, urobilinogen, blood, and nitrite.

   The 9 test items include the above 8 items plus a urine white blood cell test.

   The 10 urine analyzer test items include the above 9 items plus a urine specific gravity test.

   The 11-item test includes an additional vitamin C test.

2. For monitoring the efficacy of treatment for diagnosed conditions, such as kidney diseases, use the pH, protein, and occult blood (red blood cells) combination test strips; for diabetes, use the pH, glucose, and ketone combination test strips; for liver diseases, use the bilirubin and urobilinogen combination test strips.

How the Urine Analyzer Machine Works

Urine analyzers typically use microcomputer control, employing spherical analyzers to receive dual-wavelength reflected light and semi-quantitatively measure color changes on test strips.

The test strip contains multiple reagent pads, each containing different reagents. Each reagent reacts with specific components in the urine, resulting in different colors after the reaction. The intensity of the color reflects the concentration of the corresponding component in the urine.

The reflected light is received by a spherical integrator, and the dual-wavelength light is projected onto the photodiode of the spherical integrator. The selection of wavelengths is determined by the specific test parameters.

Precautions for Urine Analyzer Machine

1. Calibration:  

   After installing a new instrument or after each major maintenance:  

   The urine analyzer should be calibrated to ensure it operates within the manufacturer's specified parameters. Urine analysis can only be performed after calibration is successful; otherwise, the instrument must be shut down.  

2. Precautions  

   Keep the instrument clean to maintain optimal performance.  

   Ensure the use of clean sample cups.

   Use fresh, mixed urine samples. After collection, samples should be tested within 2 hours.

   Different types of urine analyzers use different urine test strips. When the test strips transition from refrigerated temperature to room temperature, do not open the cap of the bottle containing the test strips. After each use, immediately close the cap to prevent the test strips from becoming damp and deteriorating.

   The test strip should be immersed in the urine sample for 2 seconds. Excess urine on the test strip should be absorbed with filter paper. All reagent blocks, including the blank block, must be fully immersed in the urine.

   The optimal operating temperature for the instrument is 20°C to 25°C room temperature. Urine samples and test strips should also be maintained within this temperature range.

Maintenance and Care of Urine Analyzer Machines

In routine work, it is essential to strictly follow established operating procedures; otherwise, improper use may affect experimental results.

1. Each urine analyzer should have its own operating procedure, which must be followed.

2. Before starting the instrument each day, conduct a thorough inspection to ensure everything is in order before turning it on. After testing is complete, thoroughly clean and maintain the instrument.

3. Unused urine test strips that have been opened should be immediately returned to the bottle and the cap securely closed.

Conclusion

Urine analyzer machines will play an increasingly important role in the diagnosis and treatment of kidney disease, urinary tract infections, and other related diseases. The use of automated interpretation by these devices can improve patient treatment outcomes. With the growing demand for point-of-care testing, urine analyzer machines will become an indispensable tool in the healthcare field.
