Siemens PFA 100 Platelet Function Analyzer Hematology LAB B4170-00 - Working



Web Information

The PFA-100® System measures the complex process of primary hemostasis and aids in the rapid detection of platelet dysfunction. It is the first commercially available in vitro testing system to incorporate high-shear flow in which the process of platelet adhesion and aggregation following a vascular injury is simulated in-vitro.

The PFA-100 System provides automated assessment for inherited, acquired, or drug-induced platelet dysfunction.

  • Helps detect inherited, acquired and drug-induced platelet dysfunction
  • Screening test for patients with impaired primary hemostasis, such as von Willebrand disease1
  • Verifies efficacy of desmopressin acetate (DDAVP) therapy in pre-surgical patients2
  • Assesses the platelet dysfunction due to the effect of Aspirin
  • Evaluates platelet dysfunction in children over 1 year of age3
  • Evaluates platelet dysfunction in multiple clinical settings, such as presurgical screening, high-risk pregnancy and menorrhagia

Features & Benefits

The PFA-100 System has become the new standard for detection of platelet dysfunction. The PFA-100 Analyzer quickly and easily measures platelet plug formation in a small, whole blood sample (<1 mL) and reports a ”Closure Time” in 5-8 minutes. It is a unique system that challenges platelets under high shear flow conditions similar to the physiologic environment in which platelets normally function. It detects inherited-, acquired- or induced- platelet dysfunction by uniquely simulating, in vitro, the function of platelets in Primary Hemostasis

A Model of Efficiency:

  • Accurate detection of inherited, acquired or induced platelet dysfunction under high-shear stress
  • Sensitive to quantitative and qualitative abnormalities of VWD in both plasma and platelets
  • Simple, rapid and precise assessment of platelet function

Test Menu:

  • Collagen/Epinephrine and Collagen/ADP test cartridges



    • Easy to use - self-contained disposable test cartridges
    • Fast - delivers quantitative results within 5 to 8 minutes
    • Cost savings - minimal sample manipulation and maintenance required
