Thank you for your interest in the International Society for Laboratory Hematology (ISLH). Our society is the largest organization devoted to clinical laboratory hematology and we are truly international, with members in over 70 countries worldwide.

One of the major activities of our society is an annual conference held in May. Our meeting brings together 700-1,200 scientists, physicians, and technologists specializing in many areas of laboratory hematology (e.g., hematopathology, hemostasis, red cell/hemoglobin disorders) and focuses on technological and scientific advances in these fields, with an emphasis on issues relevant to diagnostic laboratories. Our members are interested in acquiring information about new discoveries, as well as updating their knowledge on the pathophysiology and treatment principles, from the perspective of diagnosing hematologic disorders. 

Our scientific conference includes a full day educational workshop, preceding a three day meeting that includes plenary, simultaneous scientific sessions and both oral and poster abstract sessions. Our members claim that ISLH is “the best laboratory hematology meeting in the world”. Please visit http://www.islh.org/2025 to watch a short video about our meeting.

ISLH engages a community of experts in the planning of its conference and in the development of online educational materials. Our website contains links to items that are greatly valued, including:

1) Links to the latest ISLH webinar, which non-members can view for free
2) Links to the latest e-learning case studies, e-learning courses and other web-based learning materials (e.g., archived webinars)
3) Links to view the top lectures from last year’s ISLH meeting (from our home page)
4) Links to the educational issue of our society’s journal, the International Journal of Laboratory Hematology (IJLH) which is available as free-access articles, covering the latest topics in laboratory hematology
5) Links to an inventory of current guidelines relevant to clinical laboratory hematology practice
6) Links to information about travel and mentorship awards that ISLH offers to individuals in developing countries

In addition to receiving a subscription to IJLH, our members receive discounted registration for ISLH meetings.

One of the major strengths of ISLH is the diversity and engagement of its membership. If you have any questions about ISLH and the benefits of membership please contact us at [email protected].
