Collecting a blood sample at home is simple with a fingerstick: warm your hand, prick the side of a fingertip, and fill the collection device following your kit’s steps.
Before you start
Wash your hands in warm water and let them warm up – good blood flow makes collection easier. Have your kit ready and read the instructions.
Collecting the sample
Prick the side of a fingertip with the lancet, wipe the first drop, then let drops fall or fill the device. A gentle “milking” motion helps flow.
Finishing up
Seal your sample, complete any labels, and mail it the same day using the prepaid packaging.
Tips for a good sample
Stay hydrated, keep your hand below your heart, and collect enough volume – the most common issue is too little blood.
