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.
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, Spectrum Health Regional Laboratory will no longer offer Magnesium, Red Blood Cell [LAB104] as an option for send out testing. This testing will no longer be available through Spectrum Health’s primary reference laboratory, Mayo Clinic Laboratories. This test will become obsolete on January 7, 2019, due to limited clinical utility.
Spectrum Health Regional Laboratory is not validated to perform Chlamydia and Gonococcus testing on pediatric patients under the age of 14 years old. Testing for these patients must be sent to a reference laboratory. Please order a Reference Miscellaneous Test (#LAB848) and indicate complete test name when ordering.
Effective August 1, 2018, Spectrum Health Regional Laboratory will no longer stock Sequenom Collection Kits. If a patient presents with a Sequenom Collection Kit, our outpatient phlebotomy staff will continue to aid the patient in collection. If needed, please order Sequenom Collection Kits from the manufacturer.
Spectrum Health Regional Laboratory will still offer Panorama Collection Kits. For more information on Panorama testing please click here.

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).
