| Collection Instructions | 1. Check the expiration date on the label of the blue top vacutainer before drawing the patient. 2. For blood collection in a sodium citrate blue top, the tube must be filled to above the Minimum Fill Indicator on the tube. It is crucial to wait and allow the tube to stop filling before removing it from the needle. 3. With use of a butterfly needle, draw about 1 cc using a separate blue top to remove air from tubing, discard the first tube and then draw a second blue top tube filled to the full extent of the vacuum. 4. Tubes should not be filled past the Maximum Fill dashed line by either using a syringe or removing the tube cap. Obtain a current PT, PTT, Platelet Count, D-dimers for DIC (Test code FDDQ) and Fibrinogen before ordering FFDP. |

| Additional information | For evaluation of primary fibrinogenolysis only. This test is commonly ordered in error. If test is ordered without a request for D-Dimers for DIC (FDDQ), FDDQ will be performed instead. If test is ordered with FDDQ, only FDDQ will be performed. If a patient is being evaluated for primary fibrinogenolysis please contact hematology at x3-1747 for pre-approval of FFDP testing. |
