How does the sampling for the dry blood card work?
We recommend using more than one finger for sampling and warming the hands under warm water beforehand to stimulate blood circulation.
You can also improve blood circulation by circling your arm and using a dry brush.
Please also make sure to drink plenty of water before taking the blood sample.
Avoid direct skin contact with the areas marked for blood collection.
The blood sample for the dry blood card is taken with a lancet (a small pricking instrument). After pricking, blood should begin to form on your fingertip.
The very first drop of blood should be wiped off with the enclosed compress.
Hold your arm outstretched over the dry blood card. The tip of your finger points downwards, over the square marked with red arrows on the dry blood card.
Keep your finger still and let about 4-5 drops of blood drip onto the card.
Please allow the dry blood card to dry for at least 45 minutes at room temperature on a flat and open surface away from direct sunlight, radiators and other heat sources before placing it in the envelope.
