Note that iodine concentration is a marker of recent intake and does not necessarily confirm insufficiency

WHO recommends urine iodine concentrations of 100-200 ug/L which is equivalent to 0.79-1.58 umol/L.

(Ref: WHO. Urinary iodine concentrations for determining iodine status deficiency in populations. Vitamin and Mineral Nutrition Information System. Geneva: World Health Organization; 2013 (http://www.who.int/nutrition/vmnis/indicators/urinaryiodine, accessed 23/2/16).)   

In pregnancy, urinary iodine concentrations of 1.2 - 2 umol/L (150 -249 mcg/L) indicate adequate iodine intake(1).
