Effective March 4th, 2020, Thrombin Time will change from a sendout reference test performed by Mayo Clinic Laboratories to an in-house test performed by Spectrum Health Regional Laboratory. This test will be performed in the Coagulation Laboratory and will include a new reference range (please see link in Test Information below).
Thrombin Time is suitable for monitoring fibrinolysis therapy, screening for disorders of fibrin formation and in cases of suspected fibrinogen deficiency states. It is also useful for the differentiation between a heparin induced prolongation of the thrombin time and fibrin formation disorders.
For questions around this test, please contact the Coagulation Department at 616-267-2740.
Thrombin Time – Epic Code: #LAB11230581, Interface Code: #11230581, CPT: #85670
Effective July 2, 2018, ionized magnesium (#LAB805) testing at Spectrum Health will be discontinued due to low volume.
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.
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.
