ABSTRACT
Aim: Selenium is an essential micronutrient and, like other nutrients, has detrimental health effects at both low and high levels in the human body. Selenium toxicity is a recorded phenomenon, and in this report, we aim to present the picture of borderline high selenium levels recorded in a Pan-India cohort.Materials and Methods: Whole blood selenium analysis was done in a cohort of 529,461 individuals, inclusive of 284,189 males and 245,272 females, respectively. The technology of Inductively Coupled Plasma Mass Spectrometry was used to derive selenium values. Average blood selenium levels were also analyzed. The reporting range of blood selenium is 60–340 µg/L. For analysis in this report, a 1 SD value of >225 µg/L was considered to be borderline high.Result: The total frequency of borderline high detected in our study was 3.5%. The average blood selenium levels in the borderline high cohort were detected to be 256 ± 33 µg/L. Geographic prevalence analysis highlighted the maximum to be from the North and North-Western regions.Conclusion: Our report is one of the few to highlight not only the frequency of borderline selenium at a Pan-India level but also to identify geographical regions of concern. Such analysis will aid in devising region-specific supplementation programs to avoid overdosing.
