Effective June 17, 2019, Anti-Müllerian Hormone (AMH) testing will change from a sendout reference test to Mayo Clinic Laboratories to an in-house test performed by Spectrum Health Regional Laboratory.
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.
Spectrum Health Regional Laboratory is not validated to perform Chlamydia and Gonococcus testing on pediatric patients under the age of 14 years old. Testing for these patients must be sent to a reference laboratory. Please order a Reference Miscellaneous Test (#LAB848) and indicate complete test name when ordering.
Effective immediately, the anion gap reference interval will be changed from 4-15 mmol/L to 9-18 mmol/L to reflect the system-wide standardization of electrolyte testing.
As of Thursday, November 7th, pediatric reference intervals for alkaline phosphatase were changed at Spectrum Health Regional Laboratory to reflect the reference intervals stated by the assay’s manufacturer, Roche Diagnostics. Their values are consistent with recommendations from CALIPER studies on pediatric reference intervals.
There has been a minor change to the influenza testing methods performed by the Spectrum Health Regional Laboratory (SHRL) to improve the accuracy and timeliness of patient results, while simplifying the ordering process for providers. In past years during respiratory illness season, the lab performed influenza rapid antigen testing due to its low cost and rapid turnaround time, with negative specimens reflexed to PCR for confirmatory testing. Approximately 85% of specimens tested by a rapid antigen method typically reflexed, with those patients charged for performing both tests.
