The PFA-100 (platelet function analyzer) simulates primary haemostasis. Its strength is simplicity in use. Without doubt, PFA-100 surpasses bleeding time in sensitivity and specificity. It could be considered as a screening tool for investigating possible von Willebrand disease. DDAVP administration ...
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 desmopres...

Despite having 98% negative and 94% positive predictive values, this test is not 100% sensitive to all platelet function defects. False-negative and false-positive results are seen. The PFA-100® is also sensitive to a large number of variables. CT results vary if blood is sampled in the...
In vitro bleeding test with PFA-100 来自 ResearchGate 喜欢 0 阅读量: 29 摘要: This study investigated the usefulness and practicability of a platelet function analyzer (PFA-100(TM), DADE-Behring, Germany) to determine individual platelet inhibition in patients treated with acetylsalicylic acid (ASA...
This test clearly identified platelet dysfunction, however, so we felt obligated to offer alternative analgesia. If the PFA is to become a useful tool, further studies are required to clarify the clinical relevance of such results.References 1 E Favaloro Clinical application of the PFA-100® ...
