Container type Blue top filled to full extent of vacuum
Amount to Collect 2.7 mL blood
Collection Instructions 1. Peripheral stick required as heparin will interfere with the test.

2. Collect 1 blue top filled to full extent of vacuum (2.7 mL blood). Check the expiration date on the label of the blue top vacutainer before drawing the patient.

3. 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.

4. 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.

5. Tubes should not be filled past the Maximum Fill dashed line by either using a syringe or removing the tube cap.

6. For patients with Hct's ≥ 55%, please contact Hematology (415-353-1747) to obtain blue top tubes with adjusted citrate volumes in order to maintain the proper citrate to plasma ratio for coagulation studies.
