Tips and Tricks for Drawing a Blood Sample

Prior to collection

  • See our complete set of preparation recommendations here.
  • We recommend drinking plenty of water to ensure a sufficient sample.
  • We recommend getting your blood flowing before your sample collection by going up and down the stairs or doing several jumping jacks.

Collecting your sample

  • We recommend drawing from the 9 o’clock position of the tip of your ring finger, as it’s generally the least calloused part of a patient’s hand that allows for the most blood flow
  • Wipe away the first drop of blood with your supplied alcohol swab, avoiding contact with the puncture site as the alcohol may expedite in sealing the wound
  • If possible, avoid squeezing your finger to draw more blood. If squeezing is required, do so just above the base knuckle. 


  • After the recommended amount of blood has been collected in your test's respective device, leave the sample to dry for approximately ten minutes (30 minutes if using the 5 Spot Card). Unless your sample was collected into a small vial, in which case, immediately proceed to the next step.
  • Close or seal the collection device, place it back into the imaware™ box, and then place the box with your sample into the provided return envelope.
