Dry Chemistry Urine Analyzer Precautions

Considerations for dry chemistry urine analyzers include:

1. Strictly follow the operating steps of the inspection items to avoid deviations in test results caused by misoperation.

2. The urine sample should be morning urine and mid-section urine. Take no less than 10 ml to ensure the urine is fresh. It is best to test within 30 minutes.

3. Urine specimens should be kept warm and protected from light during transportation to prevent the test strip from being oxidized.

4. Reagents from different batch numbers cannot be mixed.

5. Various interfering factors should be avoided during operation, such as interference from vitamin C.

6. If there is a deviation in the result, the specimen should be rechecked or retested in time. If the result is still deviated after retesting, the quality control team should be asked to review in a timely manner.

7. Pay attention to distinguish dry chemical analyzers and reagents from different manufacturers to avoid mixing and affecting the test results.

8. Pay attention to distinguishing the results of different types of experimental methods (urine sediment staining + dry chemical analyzer + negative control).

9. Avoid using urine that is cloudy, contains foreign matter, or is contaminated.

10. The urine of special groups such as pregnant women, the elderly, menstruating women, or those taking certain medications may have abnormalities, and the test results should be treated with caution.

11. The interpretation of dry chemistry analyzer results requires comprehensive judgment combined with methods such as sediment microscopy or routine urine examination.

The above are the things you need to pay attention to when using a dry chemistry urine analyzer. These precautions can help ensure the accuracy of test results and avoid misdiagnosis or missed diagnosis.
