What does this mean to the baby and his/her parents?
When a baby is identified as a carrier of haemoglobin OArab it is important to test the parents, if not done before. This way it can be confirmed from which parent this has been inherited and, at the same time, it ensures there are no risks for future pregnancies.
When either parent has been confirmed as a carrier of haemoglobin OArab, information on their implications can be found in the following page:
If a carrier is found to have reduced MCV and MCH indices, iron supplementation is not required unless the patient’s ferritin levels are reduced.
Test the baby’s parents, if not done previously (that includes: haemoglovinopathy screen, full blood count and ferritin levels). This can be done in primary care.
If the couple has other children, only test them if one parent is a carrier of OArab and the other is a carrier of beta thalassaemia or sickle cell disease (haemoglobin S). Otherwise, there is no need to test them unless they are present with health problems. It is normally recommended to postpone testing until the age of 16, to enable them to make their own informed decision.
Stress that other family members can be carriers, so it is advisable to circulate the information to first-degree relatives (parents and siblings). They can request a test called “Haemoglobinopathy screen” via their GP.
Give the appropriate information leaflets (“Information for mums and dads: your baby carries a gene for unusual haemoglobin” and “You are a carrier of haemoglobin OArab).
Make sure the patient has received his/her haemoglobinopathy card.
Explain that it is still important to have malaria prophylaxis if visiting an area where malaria is endemic.
