Coagulation

The Coagulation Laboratory offers expert interpretations of coagulation profiles and consultations in the diagnosis and management of patients with bleeding and thrombotic disorders. An extensive battery of tests is offered using advanced and progressive technologies. Consultation Services are offered for patients whose blood has been tested in this laboratory.

Coagulation tests are extremely sensitive to methods of collection and preservation. It is very important that specimen collection and processing instructions are followed closely to insure accurate test results. Please refer to the Laboratory Users Guide for our online searchable test database specimen collection instructions and other test-related information. Please contact the Coagulation Laboratory prior to specimen collection for additional testing information not covered in the Laboratory Users Guide.
