What do I do if I can’t draw blood from my finger?

If you are having trouble drawing sufficient blood from your finger, the following tips may be helpful. 

• Have someone assist you in the collection process
• Drink plenty of water before collecting your sample to ensure you’re hydrated. 
• Ensure that your hands are warm by thoroughly rinsing your hands in warm water or showering. If you have calluses on your fingers, we suggest soaking your hands in warm water to soften the skin before collection.
• Promote adequate blood flow by swinging your arms by your side or exercising beforehand.
• The best site for a finger puncture is just off the center of the finger pad. Avoid the tip of the finger.
• Make sure to place your finger on a firm surface, like a countertop, to ensure that you get the proper depth when activating the safety lancet.
• Once your finger is punctured, wipe away the first drop of blood.
• If a drop doesn’t form after puncturing your finger, try promoting blood flow by massaging your wrist down to your fingertip.
