INTRODUCTION: Evidence suggests that by using the classical non pregnant reference range for serum TSH (STSH), one might miss @entity1375 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 Indian pregnant @entity1 . OBJECTIVES: To assess the maternal and fetal outcomes using new screening criteria with upper S TSH cut off as >3mIU/L, for diagnosing @entity1375 in pregnancy. MATERIALS AND METHODS: This study was a cross sectional study, carried out in the Department of Obstetrics and Gynaecology of a tertiary care hospital, in collaboration with the Department of Endocrinology. Pregnant @entity1 with  <= 20 weeks gestation, attending antenatal OPD from December 2010 to January 2012 were included in the study. On the basis of S TSH level, @entity1 were divided into Study Group with S TSH level between 3.1 to 6.2 mIU/L, (new range to be studied) and an equal number of age and parity matched Control Group with S TSH levels between 0.4 to 3 mIU/L. The maternal and fetal outcomes were compared between study and control groups. RESULTS: During the study period, a total of 66 @entity1 had S TSH between 3.1-6.2 mIU/L. Maternal and fetal outcomes in both the groups were comparable. There was no difference in the mode of delivery between study and control groups. CONCLUSION: The lower S TSH cut off recommended for diagnosing @entity1375 in pregnancy may not be applicable to pregnant Indian @entity1 .
