INNOVANCE PFA-200 System¹
Fast and reliable platelet dysfunction detection

INNOVANCE PFA-200 System

The INNOVANCE^® PFA-200 System¹ provides automated assessment for inherited, acquired, or drug-induced platelet dysfunction. It measures the process of primary hemostasis and aids in the rapid detection of platelet dysfunction. Through flow technology, the system provides a realistic hemodynamic environment for the measurement of primary hemostasis.

Screens platelet function in patients with impaired primary hemostasis, such as von Willebrand disease²
Provides excellent sensitivity for congenital platelet dysfunction, such as Glanzmann thrombasthenia
Verifies efficacy of desmopressin acetate (DDAVP) therapy in presurgical patients³
Assesses platelet dysfunction caused by aspirin
Evaluates platelet dysfunction in multiple clinical settings, such as presurgical screening, high-risk pregnancy and menorrhagia
Detects platelet P2Y12-receptor blockades in patients undergoing therapy with P2Y12-receptor antagonists

Features & Benefits

Simple, rapid, qualitative, and precise automated assessment of platelet function

The INNOVANCE^®PFA-200 System¹ provides simple, rapid, qualitative, and precise automated assessment of platelet function and supports clinically relevant decision-making processes effecting therapies. The system quickly measures platelet plug formation in a small whole blood sample (800 μL) and reports a ”closure time” in 5-8 minutes.

Comprehensive bleeding risk assessment

The INNOVANCE PFA-200 System’s unique technology simulates in vitro hemodynamic conditions of platelet adhesion and aggregation in a vascular lesion, providing rapid detection of acquired, inherited, or drug-induced platelet dysfunction in multiple clinical settings. Combining the INNOVANCE PFA^® P2Y test¹, the Dade^® PFA Collagen/EPI Test Cartridge, and the Dade PFA Collagen/ADP Test Cartridge provides a comprehensive, cost-effective preoperative bleeding risk solution.

Simple 3-step process requires minimal pipetting and hands-on time
Results from one 800 μL sample of blood
One cut-off for P2Y samples in 3.2 and 3.8% buffered sodium
Preoperative screening results in 5-8 minutes

Detects inherited, acquired, and drug-induced platelet dysfunction

In combination with traditional coagulation screening tests such as prothrombin time and activated partial thromboplastin time, the INNOVANCE PFA-200 System provides excellent sensitivity to functional defects of hemostasis.

Accurate detection of acquired, inherited, or drug-induced platelet dysfunction under high-shear stress
Sensitive to quantitative and qualitative abnormalities of VWD in both plasma and platelets
Simple, rapid, semi-quantitative, and precise assessment of platelet function
Software supports closure curve⁴ illustrations for use in scientific studies

Reliable detection of aspirin-induced platelet dysfunction

The INNOVANCE PFA-200 System assesses whether doses are sufficient to induce platelet dysfunction. While other analyzers only detect the inhibition of platelet aggregation, the INNOVANCE PFA-200 System accurately measures the ability of aspirin to prevent platelet plug formation.

Effective monitoring of pre-surgical therapy

Several “screening tests” fail to detect a number of mild bleeding disorders that could cause substantial bleeding. The INNOVANCE PFA-200 System, however, can reliably identify patients with a bleeding risk due to platelet function deficiency. With the INNOVANCE PFA-200 System, most patients with prolonged Col/ADP Closure Times manifest abnormalities in primary hemostasis that could place them at risk during surgery.

The Dade PFA Collagen/EPI Test Cartridge provides effective assessment of pre-surgical therapy with desmopressin (DDAVP)
Several clinical studies suggest that the PFA closure time (CT) with both the Dade PFA Collagen/EPI and Dade PFA Collagen/ADP Test Cartridges becomes measurably shorter following infusion of DDAVP
Shorter closure times indicate improved platelet function and may indicate improvement in bleeding symptoms and transfusion needs

Safe and efficient testing

No special sample collection requirements–only a small volume of citrated whole blood is needed (800 μL)
All PFA tests can be run from one patient sample tube
All biological material remains in the test cartridge. This feature minimizes operator/blood contact for improved safety and consistency, avoiding instrument contamination and facilitating safe biohazard disposal
Blood samples are stable for up to 4 hours after collection
Built-in quality control program reduces risk of reporting false results
Password/access levels protect sensitive patient data and provide enhanced traceability records
