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 1/31/2018 13:00, our instrument has been replaced and there should be no delay in testing.
Serum and Urine Osmolality requests will be delayed for up to 24 hours until further notice due to instrumentation malfunction. Please contact the Chemistry Department with any questions or concerns. We apologize for any inconvenience that this may cause.
As of 1/12/2018, the analyzer has been repaired and all specimens have been resulted.
The Dynex DS2 analyzer in the Chemistry department at Spectrum Health Regional Laboratory is currently down until Tuesday, January 2, 2018. Results for TB Screen (QuantiFERON Gold) on tests collected since December 21, 2017 will be delayed. Specimens are stable for 27 days, so the patient will not need to be recollected. We apologize for any inconvenience.
If you have further questions, please contact the Laboratory Call Center or use the “contact us” link above. This post will be updated when the analyzer is serviced.
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.
Effective November 5, 2017, the 1,25-Dihydroxyvitamin D test will have its name changed to Calcitriol (1,25-Dihydroxyvitamin D) in the Epic, Cerner and eSHare systems.
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.
On March 21, 2017, Spectrum Health Regional Laboratory (SHRL) will be switching instrument/vendors that perform the Beta CTX (BCTX assay); we will be switching from the ROCHE COBAS® platform to the ISYS-IDS platform. Both methods compare very well, however reference ranges will change due to the different methods.
As of February 7, 2017 the method/instrument used for the Growth Hormone assay performed at the Spectrum Health Regional Laboratory will be switched from ROCHE COBAS to the IDS- iSYS. A method comparison between the two methods showed excellent clinical and numerical comparability. The assay also performed excellently in terms of precision and linearity.
