However, most cases of beta thalassaemia major should be detected during newborn screening, but beta thalassaemia carriers are not. Guidance on offering NBS screening, taking the sample and recording consent or decline is available in the guidelines for newborn blood spot sampling. ‘X-linked’ conditions occur when a woman is a healthy carrier, but passes on the faulty gene to a son, who then develops the condition.
