Don't worry less fetal hb may not be always thalasemmia if you and your husband r thalassemia carriers then risk of thalassemia for fetus then thalassemia testing is adviced soon after birth for the baby. Only thalassemia major is worrisome for baby. Less hb may be more commonly to anemia. U need iron rich foods and iron supplements. Thanks.

Please clarify. Is the hemoglobin 7.7 which may be normal. But if the foetal hemoglobin is 7.7% of total hemoglobin this is too high and further testing for thalassemia is essential.
