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.
