Principle and usage of urine sediment analysis system

principle:

The principle of the urine sediment analysis system is basically to determine the pathological state of the urine by centrifuging the urine sample and taking the sediment, observing and analyzing the components and quantity in the sediment.

Specifically, the urine sample is centrifuged to separate the sediment from the supernatant. The operator will then remove the sediment, observe and record the number and types of cells, bacteria, crystals and other components in it. Usually, urine sediment analysis systems use optical microscopes to observe and record these components. Some high-end equipment can also automatically count and analyze the amount of each component in the sediment.

By observing and analyzing the sediment, the urine sediment analysis system can determine whether there are hemoglobin, proteins, white blood cells, red blood cells, bacteria, crystals and other components in the urine, as well as their quantity and type. This information can help doctors determine the patient's pathological status and diagnose diseases, such as kidney disease, urinary tract infection, urinary stones, etc.

Instructions:

1. Collect urine samples: Use a collector to collect morning urine samples or random urine samples to ensure that the samples are free of impurities. Samples should be analyzed as soon as possible after collection.

2. Prepare the analytical instrument: According to the operating instructions of the equipment, connect the analytical instrument to the power supply and turn it on to ensure that the equipment operates stably.

3. Sample processing: According to the guidance of the equipment, move the sample to the system sample processing tank. The sample can be added with diluent or fluorescent reagent, and then mixed and processed.

4. Pretreatment: After the sample is mixed, it needs to be pretreated, including centrifugation, shaking and other treatments to remove impurities or suspended matter.

5. Urine sediment analysis: Add the processed sample to the analysis tank for analysis, and monitor the analysis results in real time according to the equipment settings.

6. Result processing and analysis: According to the device’s result prompts, analysts can perform data processing and analysis on the results to generate qualified reports.

7. Cleaning and disinfection: After analyzing the specimen, cleaning and disinfection are required to ensure the hygiene and reliability of the equipment.

8. Maintenance of equipment: Long-term and stable operation of equipment requires regular maintenance to ensure equipment operating status, reduce failure rates and extend service life.
