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.
Effective April 30, 2020, Spectrum Health Laboratories will no longer be performing the D-Dimer Semi-Quantitative assay. D-Dimer (quantitative) will be the only orderable for the D-Dimer assay. This D-Dimer will be reportable up to 35,000 ng/mL FEU. The cut-off value used in the diagnosis of venous thromboembolism (VTE), deep vein thrombosis (DVT), or pulmonary embolism (PE) remains at 500 ng/mL FEU. It is important to note inpatients can be (falsely) elevated in many underlying non-thrombotic conditions common in hospitalized patients.
Questions and inquiries regarding this change may be sent to the Coagulation Department using the “Contact Us” link above.
D-Dimer – [Epic Code: LAB313, Interface Code: 10123, CPT 85379]
Discontinued: D-Dimer Semiquantitative for DIC [Epic Code: LAB760, Interface Code: 10122, CPT: 85378]
Effective April 22nd, 2020, the following ANA (Antinuclear Antibodies) Tests’ name will be updated. The change in naming convention comes in hopes of enhancing proper test utilization. This update includes only the name change with no changes in laboratory testing workflow.
|Old Test Name||New Test Name||Test Code||Clinical Utility|
|ANA (Antinuclear Antibodies) Screen, Double Reflex to ANA IFA Hep2 Titer and Pattern, and if positive to ANA antibodies||ANA screen||LAB1230491||Preferred initial ANA screen for autoimmune connective tissue diseases.|
|ANA (Antinuclear Antibodies), Hep2 Substrate IFA with reflex to Titer and Pattern if positive||IFA ANA (Rheumatology)
|LAB3540||Preferred confirmatory ANA test for autoimmune connective tissue diseases. With ordering recommendations for rheumatology only.|
Effective immediately, due to low test utilization and the high cost of maintaining proficiency, the Chromosome Analysis Breakage Study will no longer be offered by the Spectrum Health Cytogenetics Department.
If need arises for this test, please place an order for a Reference Miscellaneous (EPIC# LAB848) and enter “Test 140 DEB Breakage Study to Integrated Genetics” in the comments. The testing will be sent out through Spectrum Health Referrals Department to Integrated Genetics.

Specimen Drop Off for Referring Laboratories and Referring Sites
Please review this document: Link: COVID-19 Specimen Drop Off
You must be an approved COVID collection lab. For approval please contact the Lab Call Center. All other sites and offices must direct patients to the SH Now COVID-19 Free Screening Hotline at 833-599-0659.
Nasopharyngeal (NP) swabs are the preferred specimen type.
If NP swabs cannot be collected, anterior nasal swabs may be collected as an alternative with slightly reduced sensitivity.
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.
Effective Wednesday, December 18, 2019, Cystatin C will change from a sendout reference test performed by Mayo Clinic Laboratories to an in-house test performed by Spectrum Health Regional Laboratory. This test will be performed in the Toxicology Laboratory and will include a new reference range (please see link in Test Information below).
Questions may be directed to Toxicology via the “contact us” link above.
Cystatin C – Epic Code #LAB3226, Interface #11631, CPT #82610
The most conclusive evidence for using thyroid peroxidase antibody (TPO) is predictive in nature when evaluating possible subclinical hypothyroidism. If this test is positive, hypothyroidism occurs at a rate of 4.3% per year versus 2.6% per year when the antibody is negative. While this scenario does not cover all clinical indications for ordering TPO, there is no definitive evidence that repeat TPO testing provides additional information.1
Based on this information the ordering of TPO within Spectrum Health is being modified. If the test is ordered more than once on a patient, a screen will appear in EPIC indicating the following: “This test should typically only be resulted once per lifetime. The duplicate checking indicates that this patient has already had this testing performed. Please see chart review for results.” This is not a “hard stop” but providers will need to click “Continue” to proceed with the order.
