OBJECTIVES: The aim of this study is to establish gestation-specific reference intervals (GRIs) for thyroid function assays in pregnant Chinese women with ARCHITECT and compare them to other GRI studies.
DESIGN AND METHOD: Thyroid antibody negative pregnant Chinese women were enrolled and followed to establish GRIs for thyroid function by use of the Abbott ARCHITECT i2000SR analyzer (N=1409). Samples from 360 non-pregnant Chinese women served as controls.
RESULTS: GRIs of thyroid-stimulating hormone, free thyroxine and free triiodothyronine for first trimester pregnancies were 0.16-3.78mIU/L, 10.9-17.7pmol/L and 2.9-5.0pmol/L, respectively. GRIs for second trimester pregnancies were 0.34-3.51mIU/L, 9.3-15.2pmol/L and 2.9-4.6pmol/L. GRIs for third trimester pregnancies were 0.34-4.32mIU/L, 7.9-14.1pmol/L and 2.9-4.5pmol/L.
CONCLUSIONS: Our thyroid GRIs were different from those in other Chinese studies generated on other analyzers, but were similar to a Swiss study using the same analyzer. These data should prove useful for the interpretation of thyroid function assays among pregnant women measured on the Abbott analyzer.
