Anti-Thyroglobulin Orders Received in Conjunction with Thyroglobulin Tumor Marker Orders

Effective immediately, Anti-Thyroglobulin (Anti-TgAb) requests if received in conjunction with Thyroglobulin Tumor Marker (Tg-TM) requests, will be canceled. Tg-TM tests are sent to Mayo Medical Laboratory; where both Tg-TM and Anti-TgAb are performed and resulted as part of the Tg-TM order. This is a laboratory best practice as anti-thyroglobulin autoantibodies (Anti-TgAb), which occur in 15% to 30% of thyroid cancer patients, could lead to misleading Tg results (falsely positive or falsely negative).

CK Isoenzyme Discontinued

As of March 13th, 2017 Spectrum Health Regional Laboratory will be inactivating the CK Isoenzyme orderable  (SH # 2799, Epic #LAB64).  This test is not necessary in patients with clinically consistent CK elevations such as, but not limited to, muscle disease, muscle injury or statin use. In cases of suspected statin myopathy/myositis, elevated CK coupled with statin use is enough to make the diagnosis. CK Isoenzyme testing is recommended in situations where the CK elevation cannot be explained by clinical history and physical. Moving forward, CK Isoenzyme requests will require approval from either Dr. Alter or Dr. Blue.

Any questions concerning this change may be directed to Dr. David Alter or Dr. Deborah Blue via the “Contact Us” link.
