Executive Summary
The UK's Medicines and Healthcare products Regulatory Agency (MHRA) has reported problems with Abbott Diagnostics' AxSYM and AxSYM Plus laboratory analysers. Three unrepeatable false negative results have been reported at one UK centre using an HIV assay on the AxSYM Plus analyser, the agency said in an alert dated July 13. At another centre, four unrepeatable false negative results have been reported involving a rubella IgG assay on an AxSYM system. Initial investigations suggest three potential causes: a blocked process probe, unrecovered probe crashes or the wrong sample tubes.
