Specimen Requirements:

3.2% sodium citrate tubes are acceptable provided they are filed to the line on the manufacturers label. Tubes must be full (see comments below). Test stability: see individual tests.

Pediatric Specimen Requirements:

Add blood to 1.3 mL mark of Pediatric BLUE top tube, 3.2% sodium citrate. Test stability: see individual tests.

Comments:

Draw volume is critical due to the liquid anticoagulant. Allow tubes to fill by vacuum.

  • Tubes with rubber stopper: fill to line on label.
  • Tubes with plastic (Hemogard) cap: the fill level is above the top of the label.
  • Syringe: do not remove the vacutainer stopper. Insert the needle through the stopper and allow the tube to fill by vacuum. Do not overfill the vacutainer.
  • Pediatric tubes have no vacuum. Remove the cap and add blood to the 1.3 mL mark. Do not overfill.
