Spectrum Health Regional Laboratory is adjusting the Microalbumin Analytic Measurement Range (AMR) in order to standardize within the Spectrum Health Hospital System and to align with our vendor’s (Roche Diagnostics) recommendations. The lower limit of the Microalbumin AMR will be changed from 0.50 to 1.20 mg/dL. Results below the AMR will now be reported as < 1.20 mg/dL. The upper limit will remain the same at 444.00 mg/dL.
Effective January 1, 2019, Spectrum Health Regional Laboratory will no longer offer Magnesium, Red Blood Cell [LAB104] as an option for send out testing. This testing will no longer be available through Spectrum Health’s primary reference laboratory, Mayo Clinic Laboratories. This test will become obsolete on January 7, 2019, due to limited clinical utility.
As of October 1, 2018, the reference interval for Anti-Thyroid Peroxidase Antibody levels has been updated to 0.0 to 34.9 IU/mL from 0.0 to 8.9 IU/mL. This change is due in part to client feedback resulting in an audit of the existing range and leading to discovery that it had not been updated when the instrument had been changed.
We appreciate and welcome any and all client feedback; if you identify what may appear to be an incorrect reference interval, please notify us immediately using the “Contact Us” link above.
Effective August 8th, Spectrum Health Laboratory will ask all patients to indicate how long they have been fasting (regardless of whether they were fasting or not) when they present for Lipid testing. In light of recent discussions in the literature that debate the utility of fasting prior to lipid testing; we recognize that some clinicians may now not require their patients to be fasting and hope that reporting out length of fasting (hours) with each lipid result will allow all clinicians to better interpret their patient’s lipid results. If fasting is desired; Spectrum Health Laboratory recommends no caloric or caffeine intake for at least 8 hours. The patient is not to drink (other than water), eat, smoke, chew gum, candy, cough drops, etc. for at least 8 hours prior to their blood tests. Prescribed medications are allowed.
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.
