The PFA-100 device offers a rapid, in vitro method for assessing primary hemostasis. This review suggests it is a valuable screening tool for platelet function disorders and pre-surgical evaluations.

Area of Science:

  • Hematology
  • Clinical Diagnostics

Background:

  • Primary hemostasis evaluation is crucial for diagnosing bleeding disorders.
  • Traditional methods like the bleeding time have limitations.

Purpose of the Study:

  • To review the utility of the PFA-100 device for screening primary hemostasis.
  • To assess its role in diagnosing platelet function disorders and guiding therapy.

Main Methods:

  • Comprehensive literature search including PubMed and conference abstracts.
  • Review of studies evaluating the PFA-100 for hemostasis assessment.

Main Results:

  • The PFA-100 is effective for screening von Willebrand's disease and other platelet disorders.
  • It aids in pre-operative hemostasis assessment and monitoring desmopressin therapy.

Conclusions:

  • The PFA-100 demonstrates high sensitivity, speed, and ease of use.
  • It is a suitable replacement for the in vivo bleeding time in routine clinical practice.
