Laboratory diagnosis

Accurate diagnosis is the first step in treating hemophilia. Because different bleeding disorders may have very similar clinical symptoms, correct diagnosis is essential.

The World Federation of Hemophilia (WFH) organizes a number of national, regional, and international training workshops to demonstrate practical coagulation skills and the importance of good laboratory practice. Laboratory scientists or technicians from developing countries can attend these workshops to learn proper methods and techniques for accurate diagnosis using basic equipment and technology.

National and regional workshops

National and regional laboratory workshops provide theoretical and practical training that is adapted to the needs and levels of different countries. These workshops can provide a range of training, beginning with an introduction to basic testing for hemophilia to providing more advanced skills, such as extending diagnosis to vonWillebrand disease (VWD) and other factor deficiencies. Participants include laboratory scientists and technicians selected from hemophilia treatment centres. The workshops are typically two days.

"Training the Trainers" workshops

The "Training the Trainers" coagulation workshop, held every two years, teaches clinicians and senior laboratory personnel from developing countries how to train laboratory staff in their own countries, including on the proper techniques and methods for diagnosing hemophilia and other bleeding disorders.

Organized at the Royal Free Hospital in London,U.K., in cooperation with the WFH Laboratory Sciences Committee chair, the Training the Trainers program provides participants with hands-on experience in laboratory practice, using both manual and semi-automated techniques. Emphasis is placed on the importance of internal quality control.
