Summary

Beckman Coulter, Inc. has initiated a Class II medical device recall for Access Total T4 Calibrator, Catalog No. 33805 (UDI-DI 15099590225872), covering lots 538729, 538815, 538898, 539107, and 539243. The firm determined that these lots exhibit a negative bias on DxI 600/800 instruments with slopes outside product specifications, potentially producing falsely low patient results. The recall affects 2,068 units in US commerce and 2,830 units outside the US, distributed to healthcare facilities and laboratories in approximately 70 countries worldwide.

“A false low patient result could cause a patient to undergo unnecessary additional diagnostic testing.”

What changed

Beckman Coulter issued a Class II recall for Access Total T4 Calibrator (PN 33805) across five specific lots after internal testing identified slopes outside product specifications on DxI 600/800 instruments, creating a risk of falsely low patient results. FDA classified this as a Class II recall and determined the cause to be nonconforming material or component.

Laboratories and healthcare facilities using Beckman Coulter DxI 600/800 instruments with these calibrator lots should be aware of the potential for inaccurate thyroid hormone test results. Falsely low T4 results could lead to patients undergoing unnecessary diagnostic testing, receiving treatment for disorders not present, experiencing delayed treatment for hyperthyroidism, or receiving incorrect thyroid hormone supplementation dosing during pregnancy. Facilities should await further instructions from Beckman Coulter (contact: Ian Pilcher, 952-448-4848) as the corrective action remains pending.
