Collection instructions and other information may have changed, please visit the lab catalog for more information.
Thyroglobulin Tumor Marker will continue to be a sendout. If a Thyroglobulin Antibody is ordered with a Thyroglobulin Tumor Marker, then the Thyroglobulin Antibody will automatically be canceled as Mayo Clinic Laboratories will perform the Thyroglobulin Antibody as well as the Tumor Marker.

Effective July 1, 2021, the Coagulation Department within the Spectrum Health Regional Laboratory will go live with an in-house, bovine based, Chromogenic Factor VIII assay.
This assay, a photometric determination of Factor VIII activity, is useful for monitoring coagulation factor replacement therapy of selected extended half-life coagulation factor replacements and Emicizumab therapy, a recombinant, monoclonal antibody that restores the function of the missing activated factor VIII by bridging FIXa and FX. The action of Emicizumab interferes with all APTT clot based and human chromogenic based assays, leading to an overestimation of Factor VIII activity. As such, the bovine based Chromogenic Factor VIII assay is recommended. The Chromogenic Factor VIII activity also assists in the diagnosis of hemophilia A using a 2-stage assay, particularly when the 1-stage clot based assay is normal.
