My dd has allergies one which is life threatening. When she was hospitalised in the Lourdes they did various blood tests. However, a year or so ago we got her tested further in Dublin – Stillorgan – Dr. Paul Carson in the Slievemore Clinic – he did skin prick tests which investigated more foodstuffs. She is seen in the lourdes once a year by Dr Fitzsimons who is really good on paedeatric allergies . As a starter if you dont want to get a referral to the Lourdes from your GP you could try Dr. Carson – he is really good and its a good basis to start from .
