Effective December 9, 2020, the following insect allergen components will be available:
◊ Allergen Honey Bee Component Panel – EPIC #LAB1230747, Interface #1230747, CPT 86008
◊ Allergen Common Wasp (Yellow Jacket) Component Panel – EPIC #LAB1230752, Interface #1230752, CPT 86008
◊ Allergen Paper Wasp Component rPol d 5 – EPIC #LAB1230754, Interface #1230754, CPT 86008
◊ Cross-reactive Carbohydrate Determinant (CCD) – EPIC #LAB1230755, Interface #1230755, CPT 86008
Beginning September 8, at approximately 2PM, Spectrum Health Laboratories will go live with their new lot of APTT reagent. This lot change triggered a new therapeutic curve resulting in new heparin nomograms for the system. The standard heparin therapeutic range will change from the current 45-65 seconds to a new range of 37-52 seconds based off the new curve. Reference ranges for the APTT assay will also be updated. Grand Rapids APTT reference range will be 21-27 seconds and the Regional Hospitals will be 21-31 seconds.
APTT specimens that are unable to reach an endpoint (no clot is detected), will reflex to the Unfractionated Heparin (UFH) (Test Code LAB3389) anti-Xa assay. To accommodate this change, UFH values have been added to heparin nomograms. The UFH anti-Xa assay is currently only performed in the Grand Rapids labs and valid only for unfractionated heparin. Any questions concerning these changes may be directed to the Spectrum Health Regional Laboratory Coagulation department at 616-267-2740.
Eastern Equine Encephalitis (EEE) testing is available to be ordered individually on serum or CSF. A panel for multiple Arboviruses is also available on both serum and CSF. Both tests are sent to Mayo Clinical Laboratories. Please order “Reference Lab Send Out for Miscellaneous Tests” for each test ordered and indicate test name in the required order field.
Effective May 20, 2019, Spectrum Health Regional Laboratory Cytogenetics Department is pleased to announce the launch of a new microarray platform AffymetrixTM Cytoscan® HD. The Affymetrix Cytoscan HD is designed for the accurate and comprehensive analysis of chromosomal variants in the human genome.
Effective January 19, 2019, Spectrum Health Regional Laboratory – Toxicology is proud to announce the availability of two new drug screen panels:
The Trichomonas Wet Prep test has been replaced with the OSOM® Trichomonas Antigen test.
This new lateral flow immunochromatographic test offers enhanced sensitivity through the detection of Trichomonas antigen as opposed to the traditional wet prep method, which relied on the labor intensive microscopic visualization of motile Trichomonas trophozoites. Because this new assay detects antigen as opposed to viable organism, specimen stability is also extended. When collected with a single eSwab™, specimens are stable for up to 24 hours at ambient temperature and 36 hours when refrigerated. Swabs collected for the wet prep method were only stable for 3-5 hours, so there is no longer a need for STAT delivery to the laboratory.
The treatment of non-small cell lung adenocarcinoma has become more successful due to targeted treatments based on the molecular profile of a patient’s particular tumor. The Lung Cancer Mutation Analysis panel is now available for clinical testing at the Spectrum Health Advanced Technology Laboratories (ATL).
When testing for Clostridium difficile Toxin (“C-diff”), only liquid (i.e. watery) stools should be sent for testing. Any formed or soft stools will be immediately rejected and testing will be canceled.
