Spectrum Health Regional Laboratory is adjusting the Microalbumin Analytic Measurement Range (AMR) in order to standardize within the Spectrum Health Hospital System and to align with our vendor’s (Roche Diagnostics) recommendations. The lower limit of the Microalbumin AMR will be changed from 0.50 to 1.20 mg/dL. Results below the AMR will now be reported as < 1.20 mg/dL. The upper limit will remain the same at 444.00 mg/dL.
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.
To maintain optimal specimen integrity, Spectrum Health Laboratory requests that you load your lockbox properly for winter weather temperatures. Please follow the diagram on the right to prevent freezing of specimens.
Frozen specimen should not be left in the lockbox 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.
At this time when Influenza prevalence is not widespread in the community, please order “Influenza A/B PCR” [LAB3255] when testing is needed. This applies to patients at all Grand Rapids and regional hospitals, and also system wide ambulatory patients.
Clinical guidelines no longer recommend serologic testing as a method for the diagnosis of H. pylori infection. Rather than IgG serology testing, other non-invasive testing methods such as H. pylori stool antigen and urea breath tests may be used to both diagnose and monitor response to therapy for H. pylori infection. In anticipation of an increase in stool antigen testing, currently a reference lab send-out test, Spectrum Health Regional Laboratory (SHRL) will be implementing this test as of October 29, 2018. By offering this test in-house, results will typically be available one day faster than present state.
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.
Effective immediately, QuantiFERON®-TB Gold test (QFT), the industry-leading Interferon-gamma Release Assay (IGRA) for TB detection used at Spectrum Health Regional Laboratory is being replaced by the QuantiFERON-TB Gold Plus (QFT-Plus).
The QFT-Plus is now optimized with innovative tuberculosis-specific antigens that elicit both CD8 and CD4 T cell responses, enabling a more comprehensive assessment of cell-mediated immune response to TB infection. The test principle, procedures, and specimen handling will remain the same with the one exception being that the collection kit will now consist of four tubes instead of three. Three-tube collections can no longer be accepted and will thus be canceled.
If you have three-tube collection kits, please order new four-tube collection kits in Lawson (#54909) or via the Lab Supply Order Form.
Please direct urgent questions to the Laboratory Call Center at 616-774-7721 or for non-urgent inquiries use the “contact us” link above.
Effective September 1st, 2018 the Advanced Technology Laboratories – Cytogenetics Department is proud to announce a new test: Array Comparative Genomic Hybridization (aCGH), Prenatal.
