To maintain optimal specimen integrity, Spectrum Health Laboratory requests that you load your outdoor lock box properly for winter weather temperatures. Please follow the diagram on the right to prevent freezing of specimens.
Frozen specimen should never be left in the lock box for after-hours pickup. These tests may be better preserved in the office freezer until the next day’s courier pickup.
Request for specimen pickup should be made to the Laboratory Call Center at 616.774.7721.
Supplies may be ordered using the Supply Order Form.
Laboratory retention has been updated for the following tests. Laboratory retention outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded.
Effective Thursday, October 24, 2019, Pap Test orderable will be updated to meet current ASCCP criteria
In both the inpatient and outpatient settings, the laboratory has supplied 24 hour urine containers with preservative such as acetic acid, sodium hydroxide, and boric acid. Upon review of specimen stability requirements, it has been determined that a preservative is not needed prior to collection of most 24 hour urine tests as long as the 24 hour container is kept refrigerated or on ice during the collection period.
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.

As of October 1, 2018, the reference interval for Anti-Thyroid Peroxidase Antibody levels has been updated to 0.0 to 34.9 IU/mL from 0.0 to 8.9 IU/mL. This change is due in part to client feedback resulting in an audit of the existing range and leading to discovery that it had not been updated when the instrument had been changed.
We appreciate and welcome any and all client feedback; if you identify what may appear to be an incorrect reference interval, please notify us immediately using the “Contact Us” link above.
