Primary and Secondary Hemostatic Defects: A Laboratorian’s Perspective

Primary and Secondary Hemostatic Defects: A Laboratorian’s Perspective

Advancing Healthcare Webinar Series

John Mitsios, Ph.D.

Bleeding disorders can result from “diseased” platelets or clotting factor abnormalities or deficiencies. Some bleeding problems are congenital (present at birth) while others are acquired (develop at any time during a person's life). The presentation will focus on the laboratory diagnosis of bleeding disorders, specifically on primary and secondary hemostatic defects.

We invite you to join us for the live webinar with Dr. John Mitsios, Ph.D. During this presentation he will:

  • Describe the different stages of hemostasis
  • Explain the methods routinely used in Hemostasis testing
  • Describe Primary Hemostatic Defects
  • Describe Secondary Hemostatic Defects
