Access Thyroglobulin assay, a simultaneous one-step immunoenzymatic assay, Catalog Number 33860

Access Thyroglobulin reagent lot 439163 may generate erroneously high patient results. Falsely increased Access Thyroglobulin results may lead a physician to pursue unnecessary diagnostic imaging studies and/or inappropriate therapy adjustments in patients being monitored for residual or recurrent thyroid cancer.

Access Thyroglobulin Calibrators

It has been determined through an internal investigation that the alternate Access Thyroglobulin calibrator cards for use with the Thyg reagent packs distributed in April 2023 will cause a decrease of approximately 11% in patient results.

The recalling firm characterized the potential interference effects of biotin (up to 1,200 ng/mL) on all biotin-mediated Access assays. The following six assays (Free T3-REF A13422, Total T3-REF 33830, Free T4-REF 33880, GI Mon-387687, Tg-REF 33860, TgAbII-REF A32898 displayed significant interference (defined as a result bias greater than +/-10%) at 1,200 ng/mL of biotin.

IMMULITE /IMMULITE 1000 TG

Concentrations for the level of biotin that does not interfere is not currently listed in the instruction for use for the Dimension Vista CTNI, Dimension Vista MMB, Dimension Sirolimus, ADVIA Centaur FOL, ADVIA Centaur aHBcM and the following IMMULITE assays, 3gAllergy Specific IgE, anti-HBc, BR-MA (CA15-3), CEA, Folic Acid, Gastrin, OM-MA (CA125), Thyroglobulin, and Vitamin B12, and these assays are susceptible to interference from biotin.

IMMULITE 2000/IMMULITE 2000 XPi TG

Concentrations for the level of biotin that does not interfere is not currently listed in the instruction for use for the Dimension Vista CTNI, Dimension Vista MMB, Dimension Sirolimus, ADVIA Centaur FOL, ADVIA Centaur aHBcM and the following IMMULITE assays, 3gAllergy Specific IgE, anti-HBc, BR-MA (CA15-3), CEA, Folic Acid, Gastrin, OM-MA (CA125), Thyroglobulin, and Vitamin B12, and these assays are susceptible to interference from biotin.

Beckman Coulter, Inc. is recalling Access Thyroglobulin reagent packs because some may exhibit greater than 10% imprecision at concentrations <10 ng/mL.

Access Immunoassay Systems Thyroglobulin,

The recall was initiated because In addition to Access Tg Sample Diluent, an additional diluent, Access Wash Buffer II, was added to Thyroglobulin instructions for use (IFU) for evaluation of samples having Tg levels above the reportable range of the assay. When customers interchange between diluents there is an unacceptable shift in results. A median difference of 16% (ranging from 14% to 23%) b
