Our Center of Excellence for Specialized Coagulation Testing is located at NRL’s laboratory in ICAD, Abu Dhabi. The laboratory provides comprehensive specialized testing for coagulation disorders and was set up with the support of world-class experts from Colorado Coagulation, part of LabCorp’s specialty laboratory network.

Collection and Processing of Coagulation Specimens

The accuracy of coagulation testing results is highly dependent upon the integrity of the sample. To ensure the best possible specimen, please follow the collection requirements and instructions as closely as possible.  Adherence to these guidelines will improve quality and reliable of the coagulation test results.

Clinical Significance

Specialized coagulation is state-of-the-art testing performed for the diagnosis of thrombosis and hemostasis disorders to enhance diagnostic capabilities for congenital, acquired or autoimmune coagulation disorders. Bleeding issues may be associated with a wide variety of coagulation abnormalities or may be due to trauma or surgery.  Routine clotting tests comprise of the prothrombin time (PT), fibrinogen, activated partial thromboplastin time (APTT), thrombin time and D-Dimer.  Abnormal clotting results that cannot be explained in the clinical context are investigated further with “specialized coagulation” tests.  These tests are performed by modifications of PT or APTT assays, using several plasma dilutions, in order to pinpoint specific factor deficiencies (e.g., FVIII or FIX in classical haemophilia).  Testing also includes the identification of specific factor deficiencies involved in the clotting complex cascade (intrinsic and extrinsic pathway).  Additional testing such as Protein C and protein S, Lupus anticoagulant testing is available to help to investigate a possible excessive clotting (hypercoagulable) disorder and/or to help diagnose the cause of an inappropriate blood clot such as deep venous thrombosis (DVT) or a venous thromboembolism (VTE).
