Folate (aka Folic Acid) is a test that requires the patient to be fasting in order for the results be accurate. Results are falsely elevated if the patient is not fasting. Spectrum Health Laboratories recently updated our system to hard stop a test from being collected if the patient is not fasting. Please remind your patients to fast 8 hours prior to having their blood drawn.
Spectrum Health Laboratories recommends:
• No caloric or caffeine intake for 8-12 hours prior to testing. Do not eat or drink anything except normal amounts of plain water. This also includes no smoking, chewing gum, candy, cough drops, etc.
• Take normal dosages of medications unless the provider has instructed otherwise.

As of March 21, 2022, Spectrum Health Laboratories will adopt a new C. difficile testing approach that no longer reflexes to PCR testing for indeterminate toxin enzyme immunoassay (EIA) results. Rather, PCR testing will only be available upon consultation with Infectious Disease.
Mayo Clinic recently completed a four-year review of Myasthenia Gravis serum evaluations and will be implementing changes to our testing algorithm.
The Spectrum Health Lab Coagulation Department has the following changes that will be occurring on 1/12/21 as a result of new instrumentation:

As result Calprotectin, Feces (LAB3290) will be replaced with Calprotectin, Feces (LAB1230580).
Please note the following differences between the new and previous test in terms of specimen requirements and reference ranges.

Effective March 1, 2019, H. pylori IgG serologic testing will be discontinued as an orderable test at Spectrum Health Laboratory. This testing is no longer recommended by clinical guidelines.
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.
On May 1, 2017, Spectrum Health Regional Laboratory adjusted the reference range for C-Reactive Protein (CRP) from ≤10 mg/L to ≤5.0 mg/L.
