A customer in the united states notified biomérieux that they have observed falsely low results for a patient's sample in association with the vidas® tsh 60 tests (ref.#: (b)(4), lot #:1007944800) compared to results obtained by an external laboratory.The customer stated that they had tested a patient tsh sample on their vidas, the results were as follows: patient 1: vidas result = 0.08 (units not reported).Repeat analysis with the vidas tsh obtained the same results.The sample was then sent to an external laboratory for reference testing as the customer indicated that the vidas results did not match the last time the tsh was ran for the patient.The external laboratory results were as follows: patient 1: labcorp result = 4.08 (units not reported).The customer was unsure, which test method was used by the external laboratory.The customer reported that no incorrect results were reported to the treating physician, there was no delay in reporting results, and this event did not lead to any adverse event related to the patient's state of health.A biomérieux internal investigation will be initiated.
