Each batch of AutoPure HDL-C is assayed with multiple quality control sera prior to release. To ensure adequate quality control, it is recommended that the laboratory should use a normal and abnormal commercial reference control serum. It should be realized that the use of quality control material checks both the reagent and instrument functions together. If the control values fall outside the specified limits, each of the below criteria should be cross-checked and corrected:
• Proper instrument function – wavelength setting, light source and temperature control.
• Cleanliness of probes and cuvettes.
• Bacterial contamination of wash water used by the instrument.
• Expiry date of the reagent kit.
