Reason for Recall

As stated by FDA

An average negative bias of -23% with IMMULITE 2000/IMMULITE 2000 XPi Thyroid Stimulating Immunoglobulins (TSI) when compared to other in-date kit lots, there is a potential for erroneously depressed patient results. This may lead to a delayed follow up of patients with clinical autoimmune thyroid

Recommended Action

Per FDA guidance

Siemens Healthcare issued an "Urgent Medical Device Correction (UMDC IMC 22-09.A.US)" to US customers, and an "Urgent Field Safety Notice (UFSN IMC 22-09.A.OUS)" to Outside the US (OUS) customers. The UMDC and UFSN letters provide instructions to customers to follow: When this issue occurs, there is a potential for erroneously depressed patient results. This may lead to a delayed follow up of patients with clinical autoimmune thyroid. Mitigations would include correlation of tests results with additional tests such as anti-TPO antibodies along with thyroid function tests such as total T3 and T4, free T3 and T4 and TSH results. A review of previously generated results is not recommended as results would not be used in isolation. Actions to be Taken by the Customer: Please review this letter with your Medical Director.
