Abstract

Objectives To generate thyroid hormone reference norms using electro-chemiluminescence technique.Design and methods Cross sectional study on apparently normal 4349 Delhi adults (18-86 years). Predetermined exclusion criteria (goiter, hypoechogenicity or nodularity on ultrasound, elevated anti-thyroid peroxidase antibody, hypo or hyperthyroidism and family history of thyroid dysfunction) excluded 2433 subjects leaving 1916 (916 males and 1000 females) as the reference population.Results Mean age and BMI of the reference population were 41.2 ± 18.1 years and 24.5 ± 4.4 kg/m(2) respectively. Median urinary iodine excretion was 233.6 μg/L (79-458;3rd-97th centile). The population was categorized into various age groups (18-30, 31-40, 41-50, 51-60, 61-70 and ≥ 70 years). Overall FT3 and FT4 values in the reference population irrespective of age, ranged from 2.4-8.8 (mean 4.6 ± 0.9) pmol/L and 10.1-24.8 (mean 15.40 ± 2.0) pmol/L, respectively. Mean TSH value in the reference population was 2.2 ± 0.9 mIU/L which was significantly lower than that of total population (3.8 ± 6.1; p<0.001).Conclusion FT3 values were observed to be significantly higher in men than women (p=0.001). The centiles (3rd, 5th, 10th, 25th, 50th, 75th, 90th, 95th and 97th) of FT3, FT4 and TSH were derived for reference purposes in Indian adults. This community based study in Indian adults has established mean reference intervals for FT3, FT4 and TSH for different age groups for both sexes separately using strict exclusion criteria. These can be used as reference norms for Indian adults.

Not all studies have confirmed age-related TSH elevations; studies from Holland, India, Germany, China, Italy, and the UK Whickham community survey failed to show TSH elevations with age.
“However, not all studies have confirmed these changes. Studies from Holland [89], India [90], Germany [91], China [92] as well as older data from Italy [93] and the UK Whickham community survey failed to show TSH elevations with age.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
