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.
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.
Spectrum Health Reed City Laboratory will be switching instrument vendors, from Beckman Coulter to Roche, Tuesday November 29th, 2016. The change will be seamless for all tests except Troponin and B-type Natriuretic Peptide, as both of those tests are specific by vendor they will change to reflect those of the new vendor.
Troponin I will be switched to Troponin T.
BNP will be switched to NT-ProBNP.
New cardiac marker numerical results and reference ranges will not be interchangeable with the old. The new markers are consistent with what is in place at Spectrum Health Grand Rapids, Gerber and Zeeland Hospital Laboratories. Spectrum Health Big Rapids, United and Kelsey Hospital Laboratories will be following suit over the next 12 months.
Cardiac marker (Troponin) testing should only be ordered for Inpatient or Emergency Department patients. This test is not clinically appropriate for outpatient testing due to long outpatient test turnaround time (specimen collection to result). In cases of acute/urgent medical conditions, please have the patients evaluated at an Urgent Care center or the Emergency Department.
