  | See special instructions on "Coagulation Studies." 1. Draw blood in light blue-top (citrate) tube(s). Spin down, remove plasma, spin plasma again, and place 2.0 mL of citrate platelet- poor plasma into 2 plastic vials each containing 1.0 mL. (Glass vials cannot be accepted.) NOTE: A. Specimen must be collected prior to factor replacement therapy. B. Double-centrifuged specimens are critical for accurate results as platelet contamination may cause spurious results. 2. Draw blood in light blue-top (citrate) tube(s) as a control specimen from a normal, unrelated person at the same time. Spin down, remove plasma, spin plasma again, and place 2.0 mL of citrate platelet-poor plasma into 2 plastic vials each containing 1.0 mL. Label clearly on outermost label NORMAL CONTROL. NOTE: Double-centrifuged specimens are critical for accurate results as platelet contamination may cause spurious results. 3. Freeze patient and control specimens immediately at < or = -40 degrees C, if possible. 4. Send patient and control specimens frozen on dry ice in the same shipping container. NOTE: Each coagulation assay requested should have its own separate set of patient and control vials. 5. If priority specimen, mark requisition, give reason, and request a call-back. NOTE: Please complete a "Coagulation Request Form" and forward it with the specimen. This form is supplied by Mayo Medical Laboratories. Requisitions for this procedure cannot be processed unless the information requested is supplied. |
