Test Update: D-Dimer

Effective April 30, 2020, Spectrum Health Laboratories will no longer be performing the D-Dimer Semi-Quantitative assay. D-Dimer (quantitative) will be the only orderable for the D-Dimer assay. This D-Dimer will be reportable up to 35,000 ng/mL FEU. The cut-off value used in the diagnosis of venous thromboembolism (VTE), deep vein thrombosis (DVT), or pulmonary embolism (PE) remains at 500 ng/mL FEU. It is important to note inpatients can be (falsely) elevated in many underlying non-thrombotic conditions common in hospitalized patients.

New Test: Thrombin Time

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.
