Iodine Urine (Random)

Alternative Names:

Urine Iodine (Random)

Laboratory:

Clinical Biochemistry

Test Code:

UIODI

Specimen Types:

Urine random

Container Types:

Plain 70mL pot

Transport Instructions between Sites and/or Laboratories:

Room Temperature

Assay Frequency:

Weekly

Additional Notes:

Reference Intervals:

Adults: 0.2-5.0 umol/L

Children (under 18yo): 0.3-6.0 umol/L

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 ug/L) indicate adequate iodine intake(1).
