What is quality control, and how does the electrolyte analyzer perform quality control?

The electrolyte analyzer uses advanced ion-selective electrode measurement technology to achieve detection. It is an indispensable medical device in clinical testing. In clinical testing, it mainly detects and maintains human blood. The balance of osmotic pressure in body fluids is very important in the detection of ions in patients who require large amounts of balanced fluids such as surgery, burns, diarrhea, and acute myocardial infarction.

While the application of clinical trials is becoming more and more popular, some of the problems that follow have become increasingly prominent. Electrolyte analyzers may encounter unstable test results in measurement applications. Choosing different calibration solutions can cause large deviations in the experimental report data of the same patient specimen (up to 8.2% at the maximum), which will give clinicians judgment Come hidden dangers. Therefore, in the process of use, the stability of the instrument must be ensured, and the quality control of the electrolyte analyzer is urgently needed in the work of the inspection EEG machine.Meilun

The following EEG machine manufacturers will tell you how the electrolyte analyzer performs quality control.

1. Prepare the quality control material, confirm the quality control level, confirm that the machine is in the "Ready" state, and enter the program "Quality Control/Standard Solution/Dialysis Solution/Urine Standard Essential Control 1 (or Quality Control 2 or Quality Control 3)" , Press: "Yes" key. Follow the screen prompts, open the injection door, move the quality control material to the injection needle, so that the injection needle is completely immersed in the quality control material, remove the quality control material after a beep, wipe the outer wall of the injection needle with gauze, and close The sample inlet is waiting for the output of the quality control result.

2. After the measurement is completed, the measurement result will be displayed and printed. If the measured value is within the entered target range, the measured value will be automatically saved.

3. If the EEG measurement value is not within the input target range, the operator can discard the sample or reselect the stored quality control standard. After confirming, press "READY". The instrument will work under the adjusted conditions. Enter the READY state to continue measurement or quality control measurement.Meilun

4. Use the recommended quality control solution testing instrument at least once a day to determine the repeatability and accuracy of the instrument. When measuring, the instrument must be in READY state.

The stability of the electrolyte analyzer performance is related to the accuracy of the test results. The quality control of the electrolyte analyzer involves the instrument itself, the reagents used, all aspects of the analysis process, and instrument maintenance, inspection and calibration. Doing a good job in the quality control of the electrolyte analyzer will help maintain the stability of the instrument and ensure the accuracy of the experimental results .
