Spectrum Health has been informed by Roche Diagnostics that the proprietary reagents used to calibrate our instruments and determine control values for ferritin blood level have been updated to reflect deviation of results leading to low result bias. This may have led to patient results being up to 20% lower than actual ferritin level.
Effective immediately, the OB Magnesium (Mg) reference range has been updated from 1.6 to 2.5 mg/dL to 4.8 to 8.0 mg/dL, to reflect the correct therapeutic range for patients receiving magnesium sulfate therapy. The non-OB magnesium reference range is unchanged.

OB Magnesium, Blood Level – Epic code #LAB3400, Interface code #11703, CPT code #83735

Effective March 1, 2019, H. pylori IgG serologic testing will be discontinued as an orderable test at Spectrum Health Laboratory. This testing is no longer recommended by clinical guidelines.
For Hemoglobin A1c testing, Mayo Clinic Laboratory has switched to an Ion-Exchange High-Performance Liquid Chromatography (HPLC) method (Bio-RAD D100) which is the same method of A1c testing used at Spectrum Health Regional Laboratory. They no longer offer the alternative method, boronate affinity chromatography, for A1c testing.
When A1c cannot be determined due to interferences that affect the Bio-RAD 100 method, measurement of serum fructosamine is recommended (Mayo test FRUCT).
Effective January 1, 2019, there will be an update to the routine turnaround time parameters from 3 days to 5 days for the following tests:
