Trimester-Specific Reference Ranges for Free Thyroxine Hormone in Iranian Pregnant Women
Introduction: Physiological changes during pregnancy affect thyroid function and also free thyroxine (FT4) assay methods. These impacts make immunoassays unreliable for detecting hypothyroxinemia during pregnancy. Due to pregnant women’s adequate consumption of iodine in Iran, reference ranges of FT4 needs to be obtained for this group. Materials and Methods: A total of 1077 Iranian pregnant wo...
متن کاملTrimester-Specific Reference Intervals of Thyroid Function Testing in Pregnant Women from Basrah, Iraq Using Electrochemiluminescent Immunoassay
BACKGROUND Thyroid function test results of healthy pregnant women differ from those of healthy non-pregnant women. This study aimed to determine trimester-specific reference ranges for total tetraiodothyronin (T4), free T4, total triiodothyronin (T3) and thyroid stimulation hormone (TSH) using electrochemiluminescence techniques from apparently healthy pregnant women in Basrah. MATERIAL AND ...
متن کاملTrimester-Specific Reference Ranges for Thyroid Hormones in Iranian Pregnant Women
Background. Due to many physiological changes during pregnancy, interpretation of thyroid function tests needs trimester-specific reference intervals for a specific population. There is no normative data documented for thyroid hormones on healthy pregnant women in Iran. The present survey was conducted to determine trimester-specific reference ranges for serum TSH, thyroxine (TT4), and triiodot...
متن کامل[Reference values for thyroid hormones in the population of pregnant women in Jaen (Spain)].
OBJECTIVE To evaluate thyroid function in the three trimesters of pregnancy in healthy women taking iodine and to define the reference ranges of normality in this population. DESIGN Descriptive study of pregnant women to define the ranges of normality of thyroid hormones in this population. SETTING Jaen and Osuna (Spain). POPULATION Healthy pregnant women. METHODS Thyroid hormone determ...
متن کاملFeto-maternal Outcome Using New Screening Criteria of Serum TSH for Diagnosing Hypothyroidism in Pregnancy.
INTRODUCTION Evidence suggests that by using the classical non pregnant reference range for serum TSH (STSH), one might miss hypothyroidism in pregnancy. Therefore, upper normal cut off value of S TSH should be taken as <2.5 mIU/L in the first trimester and <3mIU/L in the second and third trimester. However, two Indian studies have reported higher trimester specific reference ranges in the Indi...
