Attention Phlebotomists

Regarding TransFix/EDTA Vacuum Blood Collection Tubes*

  1. Please note, under-filling of tubes will result in an incorrect blood-to-additive ratio and may lead to incorrect analytic results or poor product performance.
  2. Since TVTs contain chemical additives, it is important to avoid possible backflow from the tube. To guard against backflow:
    1. Keep patient’s arm in the downward position during the collection procedure.
    2. Hold the tube with the cap in the uppermost position so that the tube contents do not touch the stopper in the cap or the end of the needle during sample collection.
    3. Release tourniquet once blood starts to flow in the tube, or within 2 minutes of application.
  3. Remove the TVT from the needle holder and immediately mix by gentle inversion 10 times to distribute the TransFix throughout the blood sample. Do not vortex.

*** Inadequate or delayed mixing may result in coagulation and inaccurate test results ***
