hello doctor My query is regarding thallassemia, My nephew is 2.8 years old and he is affected by Compound heterozyguos . We got to know from his DNA report. However he never needed blood transfusion.He is very active and growing well. but recently 2 months ago he was affected by viral fever that time his haemoglobin reache dto 5.1 but all these three years his haemoglobin is above 7.tested this month after 2 months of the transfusion his haemoglobin is 7.6g now. But we are really worried and not believing the reports. Doctors said her mother is silent carrier though it didn t show up in her reports and his father is having minor beta thallessemia
