Why Was This Recalled?
Customers complained of a positive bias in patient results on the IMMULITE/ IMMULITE 1000 and the IMMULITE 2000/ 2000 XPi PSA assay when compared against the IMMULITE /IMMULITE 1000 3rd Generation PSA assay. Siemens has confirmed an overall average positive bias of approximately 20% to 23% across the assay range relative to the WHO 96/670 with the IMMMULITE Systems PSA Assay. This positive bias is observed in patient values and the Siemens Tumor Marker controls (TMCO). Other commercially available controls may show this bias.
