Area of Science:

  • Clinical Chemistry
  • Hepatitis Diagnostics
  • Immunology

Background:

  • The Abbott Axsym analyser is widely used for hepatitis B virus (HBV) serological marker detection.
  • False positive results can lead to unnecessary patient anxiety and inappropriate clinical management.

Purpose of the Study:

  • To alert users of the Abbott Axsym analyser to a significant issue with false positive hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) results.
  • To ensure awareness of potential analytical interferences or performance issues with the Abbott Axsym analyser.

Main Methods:

  • This is an alert regarding observed results on the Abbott Axsym analyser.
  • No specific experimental methods were detailed in the provided abstract.

Main Results:

  • The Abbott Axsym analyser has demonstrated a tendency to produce false positive results for both hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg).
  • These inaccuracies have raised concerns among laboratory professionals and clinicians.

Conclusions:

  • Users of the Abbott Axsym analyser must be vigilant regarding HBsAg and HBeAg test results.
  • Consideration should be given to confirmatory testing or alternative methods when results are unexpected or inconsistent with clinical presentation.
