How to use the urine analyzer and precautions
A urine analyzer is a sophisticated electro-optical instrument that must be carefully maintained. Irregular operation of the instrument will disrupt the normal operation of the urine analyzer and cause undesirable results. So how to use the urine analyzer correctly? What should I pay attention to when using a urine analyzer? Let ’s take a look together.
How to use a urine analyzer
Take the semi-automatic instrument as an example:
1. Turn on the power of the instrument, observe whether the instrument is abnormal, and warm up for several minutes.
2. Select the required number of test strip paths.
3. Put the QC test tape (random accessory) into the test slot, start the run key, and the instrument will print out the QC result in a moment. It should be compared with the standard value on the test tape box. If the instrument fails, the word “ROUBLE” will be printed out. Follow the prompts to find the corresponding fault table and remove the fault.
4. Immerse the test strip to be tested in a random urine specimen. The immersion time shall be performed according to the test strip instructions. When removing, the lower end of the test strip should be close to the inner wall of the specimen cup to remove excess urine.
5. Put the test strip in the test slot within the specified time and observe the print result
Urine Analyzer Precautions
1. Keep the instrument clean and make sure to use a clean sampling cup.
2. Use fresh mixed urine. After the specimen is collected, it should be tested within 2 hours.
3. Different types of urine chemical analyzers use different urine test strips. When the test strip changes from refrigerated temperature to room temperature, do not open the cap of the test strip. The cap should be capped immediately after each use to prevent the test strip from getting wet.
4. The time for immersion of the test strip in the urine sample is 2 seconds. Excess urine samples should be sucked off with filter paper, and all reagent blocks, including blank blocks, must penetrate into the urine.
5. The optimal temperature of the instrument should be 20-25 ℃ at room temperature, and the urine specimens and test strips should be maintained within this temperature range.
6. When reporting the test results, because the various grades of urine chemical analysis are only designed with different grades of results, they cannot be interpreted by symbolic code results alone, and analysis must be performed in combination with semi-quantitative values to avoid qualitative results reporting methods being inadequate. To bring confusion to clinical interpretation.
7. The test strip should be stored in a dry, opaque, covered container, and stored in a cool and dry place. It is prohibited to put it in the refrigerator or exposed to volatile smoke.
The above is the introduction of the use method and precautions of the urine analyzer. I hope everyone understands the use method and precautions of the urine analyzer, which will be helpful to everyone.
