Detecting iodine deficiency

The following table presents the median urinary iodine concentration (UIC) that indicates iodine status among different population groups.

School age children

Median urinary iodine concentration (microgram/L) Indication of population iodine intake Indication of population iodine status
< 20 Insufficient Severe iodine deficiency
20-49 Insufficient Moderate iodine deficiency
50-99 Insufficient Mild iodine deficiency
100-199 Adequate Adequate iodine nutrition
200-299 Above requirements May pose a slight risk of more than adequate iodine intake in these populations
≥ 300 Excessive Risk of adverse health consequences (iodine-induced hyperthyroidism, autoimmune thyroid disease)

Pregnant women

Median urinary iodine concentration (microgram/L) Indication of population iodine intake Indication of population iodine status
<150 Insufficient
150-249 Adequate
250-499 Above requirements
≥500 Excessive

Lactating women and children under 2 years of age

Median urinary iodine concentration (microgram/L) Indication of population iodine intake Indication of population iodine status
≥500 Insufficient
≥100 Adequate

It is important to note that only population-level assessments of iodine status are possible from the survey methodology of casual, spot urine sample collection. Iodine status estimates based on the methodology of casual spot urine sample collection cannot be used to classify individual status and should not be presented as a prevalence of deficiency or adequacy. The information provided in the table above is frequently misinterpreted to reflect the situation of individuals. The correct interpretation is that populations with a median urinary iodine <20 microgram/L have “severe” iodine deficiency, populations with a median urinary iodine 20-49 microgram/L have “moderate” iodine deficiency, and populations with a median urinary iodine 50-99 microgram/L have “mild” iodine deficiency.
