Overview

Cross-sectional study establishes reference ranges for TSH, FT3, and FT4 in different trimesters, indicating local variations.

Key Points

  • The established reference ranges for TSH during pregnancy vary significantly by trimester.
  • First trimester TSH levels range from 0.12 to 4.10 μIU/ml, while FT3 and FT4 also show trimester-specific values.
  • Cross-sectional analysis involved 676 healthy pregnant women aged 18-40 to define these ranges.
  • The findings support the need for localized reference ranges aligning with existing guidelines.
