Before you come
Explain simply what is going to happen, without promising it won't hurt at all. Check whether the test needs fasting: for young children the fast is often shorter.
At the centre
Several centres have a box set aside for children. A parent stays beside them. The nurse takes the least blood needed: tests that share a tube are grouped.
At home
For a baby or a very anxious child, home sampling is available in all five wilayas, with a woman nurse on request.
