Automatic urine analyzer is common daily medical equipment, use process will inevitably be some fault, provide for the case under the user reference.
Fault phenomena: boot instrument self-check through, and the testing result is uric bravery former, bilirubin, ketone body, blood cells, proteins, nitrite, white, glucose, etc are all positive, macroscopic observation color, microscopic, urine dipsticks compared the results are all negative. Repeated testing is still positive.
Failure analysis: (1) the urine dipsticks pollution or failure, replace new dipsticks for positive results after still. (2) may instrument pollution, shut down after cleaning, wipe again after the test results are still positive. When considering the winter may and the temperature.
Troubleshooting: because the normal work of lab device auto urine chemistry analyzer state and the dipsticks for about 25 ℃ temperature requirements. Winter indoor temperature is too low. Open electric heaters, make the room temperature, closed instrument half an hour later, restart the test, it is normal.
Conclusion: normal maintenance and maintenance for the accuracy of inspection instrument is a prerequisite, but assurance inspection conditions are also very important. Especially the cold winter, temperature, and the accuracy of inspection is a necessary condition. So cold winter, especially the north must pay attention to medical lab devices, the temperature of the dipsticks, guarantee the accuracy of test results for clinical application, provide a reliable guarantee.
