The Hemostasis Laboratory evaluates bleeding and thrombotic disorders. Evaluations are referred from: community hospitals and healthcare providers both in the Blood Center’s region, and other communities in Washington, Idaho, Montana and Alaska. Hemophilic DNA testing (especially for hemophilia B) is performed on sample referrals nationwide.

The Puget Sound Blood Center’s Community Hemostasis Reference Laboratory has over 25 years of experience in providing quality hemostatic evaluations including testing, interpretation of results and patient evaluations. The Director, Dr. Arthur Thompson, is an academic hematologist with extensive clinical and research expertise in the diagnosis and management of individuals with hereditary or acquired bleeding or thrombotic disorders. The laboratory features considerable technical experience in a wide variety of instrumentation, reagents and available specialty testing with extensive Quality Assurance and CLIA approved procedures. Phone consultation is available from the Blood Center at any time and outpatient evaluations can be scheduled.

The Blood Center's Blood Component Therapy, Hemophilia Care and Apheresis programs are supported by the Hemostasis Laboratory and testing is also available for various research protocols.

The laboratory is staffed by two technologists. The hours of operation are from 8:00 a.m. to 4:30 p.m., Monday through Friday, excluding holidays.

The analytic times for testing are based on a routine work schedule. Turnaround time can be altered based on clinical need and pre-approval by a Blood Center Director or the Hemostasis Laboratory staff.
