I appreciate the interest and concern shown by Dr Kapil regarding the high urinary iodine excretion in Delhi children from upper socioeconomic strata. We have earlier also shown high UIE using the same method from Delhi and other cities(1). Similar trend of high UIE has also been reported from Delhi in another study(2). While we have not looked at the patterns of food consumption, salt consumption or estimation of salt iodine content, the sources of excess UIE remains speculative and this has been accepted by us in our paper.

The number of samples studied (1000 approx) for evaluating UIE in a sub group of USES children is by no means a small number. I agree with Dr Kapil that different methodologies can report different values of UIE, but we have used the same Wet Ashing method using perchloric acid vanadate as in earlier studies.
