Recall Insight
This recall's affected scope, documented in the Recall Profile below, stays within a single-region or limited-distribution footprint. Distribution scope (see Distribution below) directly affects the consumer exposure window and determines whether a recall remains regional or escalates into a nationwide advisory.
Within the same product category the archive holds 6 closely related recalls, 6 from FDA Devices - clustering in a narrow category often points to a systemic quality-control or supplier issue rather than a one-off defect. Always verify the recall number against the official agency record before acting.

Product description
AIA-900 Automated Immunoassay Analyzer, product code 022930 /022930R Product Usage: The AIA-900 is capable of performing three methods of immunoassay: an immunoenzymetric (IEMA) or sandwich immunoassay, a competitive binding (EIA) immunoassay, and a two-step immunoenzymetric immunoassay. An antigen-antibody reaction begins by combining a patient sample, control, or calibrator with a diluent in an immunoreaction test cup from the AIA-PACK reagent series.
Reason for recall
Tosoh Bioscience has become aware of a potential issue with the axis base of the turntable rotation drive motor on the AIA-900 Analyzer. If the tension of the timing belt between the turntable rotation pulley and drive motor is not adjusted correctly, it is possible to increase the lateral load on the motor axis resulting in the inclination and damage of the motor axis. Since January 12, 2017, Tosoh has been inspecting the tension of the timing belt during scheduled preventative maintenance visit and correcting the analyzers where this issue has been observed. If the drive motor fails, the AIA-900 analyzer will cease to function and will be unavailable for use. If this issue occurs, there may be a delay in testing and reporting patient test results. Tosoh has received five (5) complaints related to this issue with no serious injuries reported.
