Update: Platelet Aggregation Studies

The Spectrum Health Regional Laboratory Coagulation Department will be going live with the Helena AggRam analyzer on February 3, 2021.  This analyzer uses platelet rich plasma to analyze human platelet aggregation which is measured by absorbance.  The following aggregating agents are used in these studies: Arachidonic Acid, ADP, Collagen, Epinephrine, and Ristocetin.

Patients for platelet aggregation studies should be resting, fasting, and non-smoking. Patients should avoid taking any prescription or over the counter medications known to affect platelet function for ten (10) days to two (2) weeks prior to the studies.

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.

For questions around this test, please contact the Coagulation Department at 616-267-2740.
