Hematology and Coagulation Clinical Services 

The Hematology Laboratory reports an average of 170,000 test results per month. Of these approximately 60 percent are automated test results (CBC, differential, PT, APTT, fibrinogen, urinalysis, and hemoglobin fractionation). The remaining results are derived from manual tests including erythrocyte sedimentation rate, sickle cell testing, erythrocyte G6PD evaluation, and a comprehensive array of specialty coagulation tests including heparin monitoring by anti-Xa analysis, and tests for coagulation factor analysis and hypercoagulability.
