Test Details
7 days
- Thrombosis Profile
- Hypercoagulability
- Prothrombotic Evaluation
Specimen Requirements
Collect specimen in 7 blue top (citrate 3.2%) tubes. Mix by inversion. Specimen should arrive at lab within 3 hours of collection; transport at room temperature. Alternatively, centrifuge, aliquot plasma into 7 plastic tubes, and freeze the specimen within 4 hours of collection. Transport frozen specimen on dry ice. Collection of the blood through lines that have been previously flushed with heparin should be avoided. If the blood must be drawn through a VAD (vascular access device), the line should be flushed with 5 mL of saline and the first 5 mL of blood or six dead space volumes of the VAD discarded.
Please provide clinical history (brief description of the reason for testing, e.g., history of easy bruising and menorrhagia, family history of von Willebrand disease) and a listing of current and recent medications, including oral contraceptives, anticoagulants, and factor replacement therapy/DDAVP.
To reduce inappropriate thrombophilia testing in the inpatient population this test has been removed from the inpatient test catalog. If there is a specific clinical need for this test on an inpatient please contact the Coagulation Laboratory.
Additional Information
Panel includes PT (Prothrombin Time), PTT (Activated Partial Thromboplastin Time), Antithrombin III Activity, Factor VIII Assay, Fibrinogen (clottable), Fibrinogen Antigen, Plasminogen Activity, Protein C Activity, Protein S Antigen (Free), Activated Protein C Resistance, Hexagonal Phospholipid Neutralization, and Dilute Russell's Viper Venom Test. The following tests are not included in the profile, but may also be considered as part of an evaluation for a prothrombic state: Cardiolipin Antibody, Plasma Homocysteine, and Prothrombin 20210 Mutation Detection. Test may include pathologist interpretation of results at an additional charge. By ordering this test, the clinician acknowledges that a pathologist interpretation will be performed and billed as a separate additional charge if indicated.
