Trimester-specific thyroid hormone reference ranges in Sudanese women.

Background: Trimester-specific reference ranges for T3, T4, and TSH need to be established in different communities. Neither Sudan nor other African countries have established trimester-specific reference ranges for TSH, free T3 (FT3), and free T4 (FT4) in healthy pregnant women. This study aimed to establish trimester-specific reference ranges for TSH, FT3, and FT4 in healthy pregnant Sudanese women.

Thyroid Function/Antibodies in Sudanese Patients with Preeclampsia.

Preeclampsia is an important cause of maternal and prenatal morbidity and mortality in the developing countries. Changes in thyroid function/antibodies profiles in preeclamptic women are controversial and were never investigated before in Sudan. A case-control study was conducted at Medani Hospital, Sudan, to investigate thyroid function/antibodies in preeclampsia.
