AIA-2000 Analyzer, Model Nos. AIA-2000LA, AIA-2000ST - Product Usage: The AIA-2000 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.

Recall Insight
This FDA Devices action (record #Z-0475-2019) was formally reported on November 28, 2018, with the manufacturer initiating the action on September 28, 2018. It is classified under Moderate severity (Class II), with a current status of Terminated. Tosoh Bioscience Inc is listed as the recalling firm, operating out of Grove City, OH. Federal records indicate 7 units are affected.
The documented reason for this recall is: There is a possibility that the liquid suction pump on some AIA-2000 analyzers may not perform as intended and cause an insufficient volume of wash solution to be removed during the washing step. Incomplete washing of t… Distribution data in the federal record shows the product reached: US Nationwide distribution in the states of Florida, Kentucky, Maryland, Ohio, Pennsylvania, and Texas.. Distribution scope directly affects the consumer exposure window and determines whether a recall remains regional or escalates into a nationwide advisory.
To put this record in context, PlainRecalls indexes 83,949 recalls across the FDA, CPSC, NHTSA and USDA FSIS going back to 1995. Within the same product category, the database holds 6 closely related recalls, of which 6 were also issued by FDA Devices. That clustering is a signal — repeated actions in a narrow category often indicate a systemic quality-control issue, a supplier-wide contamination, or a design defect that has propagated across product lines. This recall is roughly 8 years old; older recalls can remain relevant because many units enter resale, rental, and secondary-market channels where the original warning never reaches the end user. Always cross-check the recall number against the official agency page before relying on any summary.

Product Description
AIA-2000 Analyzer, Model Nos. AIA-2000LA, AIA-2000ST - Product Usage: The AIA-2000 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
There is a possibility that the liquid suction pump on some AIA-2000 analyzers may not perform as intended and cause an insufficient volume of wash solution to be removed during the washing step. Incomplete washing of the sample may result in falsely elevated test results for the sandwich assays and falsely decreased test results for the competitive binding assays. Insufficient washing is detectable through review of the calibration data and QC trending. For example, if incomplete washing occurs, the reported values for the zero- calibration rate will be above the acceptance range. The calibration value may shift and the instrument will not calibrate successfully. If this issue occurs, there may be a delay in testing and reporting patient test results. There have been no user or patient injuries reported related to this issue.
