Platelet function testing with best-in-class predictivity

Blood platelets play a pivotal role in physiological hemostasis, but also in the development of arterial thrombosis (myocardial infarction and stroke).

Platelet function testing is utilized in the analysis of inherited and acquired platelet function disorders that may cause a transient or permanent bleeding tendency. The Multiplate analyzer can detect platelet dysfunction and thus aid in the therapeutic management of such patients.


It can also be used for monitoring of antiplatelet drugs where both compliance and drug effectiveness are key issues. It was shown with Multiplate results1 that up to 20% of patients do not respond adequately to clopidogrel treatment. These patients have a 5 – 10 fold increased risk of stent thrombosis, stroke and myocardial infarction1- 4 following percutaneous coronary interventions. Multiplate delivers best-inclass predictivity 5 and evidence is available demonstrating that Multiplate guided antiplatelet therapy has the potential to improve patient outcome.6-8

The Multiplate analyzer also plays a role in the analysis of platelet function in anesthesia and intensive care, where platelet dysfunction can lead to severe bleeding complications. The detection or exclusion of platelet dysfunction before invasive procedures or in bleeding patients can aid the risk stratification and management in these situations.9-10

  • High throughput: 30 tests/hour
  • Sample volume: only 300 μL per analysis
  • Fast turn-around time: 10 min/test
  • ADPtest: ADP induced platelet activation sensitive to clopidogrel, prasugrel and other ADP
    receptor antagonists 
  • ASPItest: Cyclooxygenase dependent aggregation (using arachidonic acid) sensitive to
    Aspirin®, NSAIDs and other inhibitors of platelet cyclooxygenase
  • COLtest: Collagen induced aggregation
  • RISTOtest: vWF and GpIb dependent aggregation (using ristocetin)
  • TRAPtest: Platelet stimulation via the thrombin receptor (using TRAP-6), sensitive to IIbIIIa
    receptor antagonists
  • Prostaglandin E1 reagent: For the assessment of ADPtest HS (high sensitivity). For the assessment of positive
    (i.e. abnormal) controls of the ADPtest
  • ASA reagent: Inhibitor of cyclooxygenase. Addition of ASA reagent to the blood sample leads to
    reduced aggregation responses in ASPItest and COLtest
  • GpIIb/IIIa antagonist reagent: Inhibitor of the platelet GpIIb/IIIa receptor. Addition to a blood sample leads to
    strongly reduced aggregation in the TRAPtest
  • Hirudin blood tubes: Anticoagulant for platelet function analysis with physiological calcium
  • Liquid control set: Quality control for electrical signal in impedance aggregometry based on the
    analysis of an artificial liquid control material
