Referral/Sendouts

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.

Test Discontinuation: Cell Hold by Flow Cytometry

As of 1/1/2017, the Flow Cytometry Laboratory at Spectrum Health Advanced Technology Laboratories will no longer accept specimens on hold.  The orderable Cell Hold by Flow Cytometry has been queued for inactivation. If a sample is received on hold after 1/1/2017, the ordering provider will be contacted for clarification, and appropriate testing will be performed based on the type of sample received.
