HSV Testing Update

In an effort to streamline laboratory processes and provide expedited results, the test Herpes Simplex 1 / 2 IGG IGM was replaced with Herpes Simplex Panel on July 17, 2019.  The new panel will still offer both Herpes IgM and Herpes IgG.  The conversion to this panel will allow the lab to report Herpes IgG results faster.  Continue Reading

Collection Update to QuantiFERON Gold

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.

Immunochemistry, Test Utilization

Test Utilization: Cardiolipin Antibody Testing

Listed below are the Cardiolipin Antibody tests available in the Spectrum Health Regional Laboratory (SHRL) catalog. Please review the tests and the recommended test utilities.

Cardiolipin IgA testing should not be ordered unless the patient is negative for IgM and IgG. It should be restricted to very specific clinical scenarios for the evaluation of patients with suspected APS (Antiphospholipid Antibody Syndrome). Cardiolipin IgA requests will be reviewed for presence or absence of IgM/IgG testing.
