Pregnancy TSH and FT4 Reference Intervals from Longitudinal Data

Supplemental tables and figures for a study establishing pregnancy-specific reference intervals for Thyroid-Stimulating Hormone (TSH) and Free Thyroxine (FT4). The data is derived from longitudinal observations collected from preconception through gestation. The author is Leonie T.L. Warringa.

Use Cases

• Establish pregnancy-specific reference intervals for TSH and FT4 levels across gestational stages.
• Analyze longitudinal trends in thyroid hormone levels from preconception through gestation.
• Validate clinical thresholds for thyroid function monitoring during pregnancy using the provided supplemental data.

Strengths

• Data is directly linked to a peer-reviewed scientific manuscript on pregnancy-specific thyroid reference intervals.
• The longitudinal study design captures hormone level changes from preconception through gestation.

Limitations

• The dataset's structure, including row count, column names, and file formats, is unspecified.
• The sample size and demographic or geographic scope of the underlying study are not provided.
