Need Support with a QC Product?

If you're experiencing unexpected QC results, here are some steps you can take before contacting support:

Verify Product Information

  • Confirm the correct product, lot number, and level are in use.
  • Check expiration dates and storage conditions (please check details in Lot Specific Product Documentation and Instructions for Use).

Review Instrument Settings

  • Make sure all reagents used in the analysis are within their expiry dates and have been stored according to the manufacturer's instructions. Expired or improperly stored reagents can significantly affect QC performance.
  • Ensure that the instrument has been calibrated recently and according to the manufacturer's recommendations. If QC results are unexpectedly out of range, consider performing a recalibration, especially if there have been recent changes in reagents, maintenance, or environmental conditions.

Evaluate Data Trends

  • Monitor QC trends – Look for shifts, patterns, or increased variability over time using Levey-Jennings plots or other available tools.
  • If relevant compare with historical data for the same lot and level.

Check for Handling Issues

  • Make sure the QC material was prepared and handled according to the instructions for use.
  • Avoid repeated freeze-thaw cycles if the material is stored frozen.

Rule Out External Factors

  • Consider changes in environmental conditions or sample integrity.

If you still have concerns after reviewing these points, please contact us with the following information:

  • Product name and lot number
  • Levels affected
  • List of analytes involved
  • Instrument and method used
  • Description of the issue
  • QC data and Levey-Jennings charts, if available
