I read the study by Nikhita et al.[1] published in April–June 2018 issue of the Journal of Clinical and Scientific Research. Using thyroid function tests (TFTs), the authors screened for thyroid disorders medical undergraduate students of 17–19 years of age group studying in Sri Venkateswara Institute of Medical Sciences, Sri Padmavathi Medical College for Women, Tirupati, India.[1] They found among the studied cohort, a single subject with subclinical hypothyroidism. The thyroid-stimulating hormone level of this subject was 8.1 mIU/L that was considered to be mildly elevated from the normal range and the thyroxine level was 89 ng/mL that was within the normal reference range.[1] I assume that such low prevalence of thyroid dysfunctions ought to be cautiously taken owing to the presence of the following methodological limitation. In the methodology, the authors mentioned that they analysed for TFTs on Beckman Coulter Access 2 Autoanalyser (Chaska, Minnesota, USA) by chemiluminescence immunoassay method.[1] It is explicit that interpreting TFTs values in a given population needs reference norms for that population. Actually, certain population-specific TFT reference ranges have been constructed.[2],[3] India has already constructed the mean reference intervals for TFTs for different age groups for both genders separately using strict exclusion criteria to be employed in the clinical setting and researches.[4] Regrettably, Nikhita et al.[1] did not mention which reference intervals of TFTs employed in the study methodology to analyse the data. I assume that employing national reference values could better elucidate the profile of disordered thyroid functions.
