Study design: Cross sectional

Settings: Holy Family Hospital Rawalpindi

Duration: 6 months, 1^st July 2021 to 31^st December 2021

Mode of delivery in females as 28(56%) normal spontaneous vaginal delivery and 22(44%) undergoes C-section. Standard error of mean, Standard deviation and percentile values were calculated in maternal group of females.

Conclusion: Trimester particular reference ranges of TSH, FT4 and FT3 of our study were lower than international recommenced levels of 2017 Guidelines of American Thyroid Affiliation. These values may be utilized to compare thyroid disease in pregnancy in our area
