Perbaikan mindray bc-3600 Hasil WBC selalu rendah

Introduction

This tutorial provides step-by-step instructions for troubleshooting and repairing the Mindray BC-3600 hematology analyzer, particularly when it consistently reports low white blood cell (WBC) counts compared to other devices. Understanding how to address this issue can improve the accuracy of blood sample readings and enhance the reliability of patient diagnostics.

Step 1: Initial Diagnosis of the Device

• Begin by checking the device's error logs for any recorded issues.
• Inspect the calibration settings to ensure they are accurate and up to date.
• Review the sample handling procedures to confirm they meet the required standards.
• Verify that the reagents used are fresh and properly stored.

Step 2: Inspecting the Sample Chamber

• Open the sample chamber and clean it with a lint-free cloth to remove any debris or residue.
• Check for any physical obstructions or damage within the chamber that could affect readings.
• Ensure that the optical path is clear; sometimes, dirt or scratches can lead to inaccurate readings.

Step 3: Calibration of the Device

• Perform a quality control check using standard control samples.
• If necessary, recalibrate the device by following these steps:
  • Access the calibration menu through the main interface.
  • Select the appropriate calibration protocol for WBC counts.
  • Follow the on-screen instructions to complete the calibration process.

Step 4: Evaluating the Reagents

• Confirm that the reagents are not expired and are appropriate for the BC-3600 model.
• If the reagents are old or improperly mixed, replace them with fresh supplies.
• Conduct a reagent performance test to ensure they produce accurate results.

Step 5: Software Updates

• Check if the device firmware is updated to the latest version.
• If an update is available, download and install it according to the manufacturer’s instructions.
• Restart the device after the update to apply the changes.

Step 6: Running Control Samples

• After completing the previous steps, run several control samples to assess the device's performance.
• Compare the results with the expected values to see if the WBC counts have improved.
• Document any anomalies and adjust the troubleshooting steps as necessary.

Conclusion

By following these troubleshooting steps, you can effectively address the issue of consistently low WBC counts on the Mindray BC-3600. Regular maintenance, calibration, and reagent management are essential for ensuring accurate blood sample readings. If problems persist, consider reaching out to technical support for further assistance or potential repairs.
