Abstract:
Objective To deduce the normal range of thyroglobulin ( Tg ) of adults senum in Liaoning Province . Methods From February to November 2017 , in Kangping County of Shenyang ( inland group ) and Gaizhou City of Yingkou (coastal group), the Tg levels of adults in different age groups were investigated according to the cluster stratified sampling method. Adults were divided into young (18 - 44 years old), middle (45 - 59 years old ) , and elderly (≥60 years old ) groups , and fasting blood samples were collected . Levels of Tg , thyroid function [ thyroid stimulating hormone (TSH), free triiodothylaminogenic acid (FT3), free thyroxine ( FT4 ) ] , thyroglobulin antibody (TgAb) and thyroid peroxidase antibody (TPOAb) were determined by automatic electrochemiluminescence immunoassay analyzer. Statistical analysis was performed on Tg measured values of normal thyroid function and antibody-negative adults, and the percentile range (P2.5 - P97.5) was used to calculate the 95％ normal range of both sides. Results A total of 685 adults were included, with a Tg level of 9.86 μg/L, including 333 adults in the inland group with a Tg level of 8.97 μg/L, and 352 adults in the coastal group with a Tg level of 10.44 μg/L. There were 255 males and 430 females, Tg levels were 9.39 and 9.99 μg/L, respectively. There were 179, 307 and 199 adults in the young, middle and elderly groups, Tg levels were 8.84, 9.22, and 11.73 μg/L, respectively, the differences were statistically significant (H=9.607, P<0.05). The normal range of Tg in adults was 1.23-58.63μg/L, and the normal ranges of Tg in the young, middle and elderly groups were 1.62 - 41.90, 0.99 -54.58, and 0.94 - 85.78 μg/L, respectively. Conclusion Successful establishment of the normal range of adults serum Tg in Liaoning Province.
