Lipaemia rarely interferes with common serum analytes on the Bayer Opera analyzer. A lipid-clearing agent, LipoClear, showed minimal impact on most test results, confirming assay reliability.

Area of Science:

  • Clinical Chemistry
  • Laboratory Medicine
  • Analytical Biochemistry

Background:

  • Interference from lipaemia in serum analyte analysis is a known issue.
  • Existing information on lipaemia interference is often brief and not instrument-specific.
  • The Bayer Opera is a widely used clinical chemistry analyzer.

Purpose of the Study:

  • To assess the degree of lipaemia interference on common serum analytes using the Bayer Opera.
  • To evaluate the effectiveness of LipoClear, a lipid-clearing agent, in mitigating lipaemia interference.

Main Methods:

  • Serum samples with varying triglyceride levels (mean 6.89 mmol/L) were analyzed.
  • Fourteen common chemistry analytes were measured before and after treatment with LipoClear.
  • Results were compared to determine the impact of lipid removal on analyte concentrations.

Related Experiment Videos

Main Results:

  • No significant critical differences were observed for most analytes after LipoClear treatment.
  • Expected decreases in total protein, phosphate, cholesterol, and triglyceride concentrations were noted.
  • The study indicates minimal interference from lipaemia for most analytes on the Bayer Opera.

Conclusions:

  • Most common serum analytes analyzed on the Bayer Opera are not significantly affected by lipaemia.
  • LipoClear effectively removed lipids without critically impacting most analyte results.
  • Quantification of lipaemia interference is recommended when method sheets indicate potential issues.
