Manufacturer Narrative

The investigation determined that a lower than expected tsh result was obtained from a patient sample when diluted 2x using vitros hsda lot 2190 when compared to the tsh obtained from the same sample diluted 2x using hsda lot 2180.The assignable cause for the lower than expected vitros tsh result was an incorrect value for the tsh baseline concentration for vitros hsda lot 2190 on the assay data disk (add) / mag card.It was determined that the baseline tsh concentration for hsda lot 2190 was incorrectly defined in the add/mag card as 112 miu/l instead of 0.112 miu/l.The baseline tsh concentration is subtracted out of the final numerical tsh result when an on-board dilution is performed.The incorrect hsda value (112 miu/l versus 0.112 miu/l) impacted the calculated tsh result leading to a negatively biased tsh result when the sample was diluted.(b)(4).

Event Description

The investigation determined that a lower than expected vitros tsh result was obtained from a patient sample that was diluted 2x using vitros high sample diluent a (hsda) lot 2190 compared to the tsh result obtained from the same patient sample diluted 2x using hsda lot 2180.The sample was tested using vitros tsh lot 6610 on two different vitros 5600 systems.Vitros tsh = 40.62 miu/l (dilute with hsda lot 2190) versus expected 150 miu/l (dilute with hsda lot 2180).Biased results of the magnitude and direction observed may lead to inappropriate physician action if they were to occur undetected.The lower than expected vitros tsh result was reported outside of the laboratory; however, a corrected report was issued with a vitros tsh result of 150.0 miu/l.No treatment was started, stopped or altered based on the lower than expected vitros tsh result reported and there was no allegation of patient harm as a result of this event.This report corresponds to ortho clinical diagnostics inc (ortho) complaint (b)(4).

Manufacturer Narrative

Ortho has reported this as a class iii recall to oradevices1recalls@fda.Hhs.Gov on 22 november 2021.A communication (cl2021-287) was sent on (b)(6) 2021 to customers who have been shipped vitros high sample diluent a (hsda) lot 2190.The communication advised customers of the issue with lower than expected tsh results when using hsda lot 2190 for onboard dilution and advised that vitros hsda lot 2190 be discontinued to dilute samples tested with vitros tsh reagent.The communication indicates that if their facility does not use the vitros tsh assay, they may continue to use the vitros hsda lot 2190.However, if their facility does use the vitros tsh assay, ortho will replace their inventory of hsda lot 2190.

Event Description

This supplemental mdr report was created to document this event was reported as a class iii recall and a communication was sent to customers.This report corresponds to ortho clinical diagnostics inc (ortho) complaint number (b)(4) and ivd 498283.
