Effective Monday, March 25, 2019, Syphilis Antibody Screen IgG [LAB3076] will change to Syphilis Total Antibody Screen [LAB1230501]. This test is also included in the Prenatal Screen (OB Panel) [LAB1230094].
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
