Thyroid hormone measurements were performed using a Chemiluminescent Microparticle Immunoassay (CMIA), an immunoassay analyzer (ARCHITECT i1000SR, Abbott Lab., Abbott Park, IL, USA), and specific, dedicated diagnostic kits (ARCHITECT Free T3, FT4 and TSH assay, Abbott Lab., Abbott Park, IL, USA), as previously described [16 (link)]. The conventional reference intervals for FT3, FT4, and TSH were 1.71–3.71 pg/mL, 0.7–1.48 ng/dL and 0.35–4.0 µIU/mL, respectively.
