Due improperly formulated and released bulk lot of fluorescence in situ hybridization (FISH) probes resulting in false positive identification results for Staphylococcus aureus and Streptococcus spp.

The product was recalled because stability evaluation of the lots indicated a decrease in reactivity that could lead to a potential false-negative result interpretation. The issue was identified by the firm after failing to meet lot requirements for potency. The lot release error was discovered on October 08, 2021, after a failed potency test was determined during 6-month stability evaluation of retention material for the lots. The subsequent manufacturing investigation, which included a review of the lot release potency documentation, found that the initial lot release potency test for the lot was misinterpreted.

Due to an unusual increase in the positivity rate with human IgM antibodies to cytomegalovirus (CMV) Enzyme Immunoassay (EIA).

Abbott has identified potential performance issues for the Alinity m System software version 1.6.5: 1) In a unique scenario, the waste chute flapper was found to not open when the Systems Solution drawer was closed and locked. It was found that the software will cause the flapper door to stay in the closed position when the drawer is closed and locked if the flapper had previously been moved out of position. 2) Sample preparation drawer #1 barcode information is used instead of sample prep drawer #2 when the scanned data is not sent to the System Control Center before the next bottle barcode in sample prep drawer#2 is scanned. 3) Under a specific condition, while the system is processing tests and a new test request is made, when the level of the bulk solution is too low to process a test, the software would error stop the system and try to complete all in-process tests. An internal counter is reset which can cause reaction vessels (RVs) already present in an Amplification Detection Unit (or amp detect) to remain there and not be moved to waste so that more RVs can be placed into the amp detect for processing. 4) 4 to 6 replicates of the same auto calibrator orders can be run with 2 different sets of calibrator materials on the same rack. It was discovered during internal testing, when running 4 to 6 replicates of a calibrator, it is possible for the user to use 2 separate lots of material which is not detected by the System Control Center (SCC). If this were to occur, the calibration curve would be created using 2 separate material lots. In normal use scenario, this curve would be made using only 1 lot of material.

Calibration disk Data Release Version (DRV) 6194 to 6200 contain inappropriate calibration mathematics for VITROS Calibration Kit 9 for calibrating VITROS PHYT Slides, for all lots of slide generation 22 (GEN 22). The erroneous mathematics on the calibration disk prevents the VITROS 250/350 Chemistry System from successfully calibrating, leading to delayed results.

Ambulatory ECG monitoring system labeling update: 1) Clinically actionable arrhythmia notifications delayed until patient registration is complete; 2) Patches limited to 100 symptomatic and 500 asymptomatic wireless transmissions; once the maximum transmission limit is reached for either type, any further transmissions for that type will cease. Risk of delayed reporting to health providers.

Weak skin adhesion.

Due to partial label detachment on tubes. This can cause tubes to become stuck together in the pouch or cause automation errors when used with the automated loader for the wash assistant.

Firm root cause investigation confirmed that label detachment is due to an adhesive change by a tier 2 supplier.

Unable to charge the battery pack- battery packs will allow the batteries to be charged if the voltage of any cell is below 2.5V. When this occurs, the battery pack will not accept the charge, could vent and possibly catch fire

Assigned vial lot numbers for the incorrect type of product. SARS-CoV-2 & Flu A/B lot numbers were incorrectly assigned to the positive and negative vial lot numbers for SARS-CoV-2 Ag LQCs within batch 2002204017, which should have been assigned SARS-CoV-2 Ag lot numbers resulting in an error message and preventing use of the LQC

Potential for falsely elevated LITH_2 and Li results on the Atellica CH 930 Analyzer. In the worst case, there is a potential for erroneously elevated lithium patient results, which may lead to inappropriate dosage adjustment, potentially affecting treatment efficacy.

Reported false positive and invalid results on the affected devices due to anomalous baselines. This may lead to erroneous or delayed diagnoses.

COVID test kit shelf life was periodically extended, as real-time stability test timepoints passed, without FDA concurrence.

Kit incorrectly labeled for use with COVID testing and should not be used with any SARS-Co-V2 device.
