Urine samples with values abovethe standard curve were first diluted at 1 in 5, followed by dilutions of1 in 10 and 1 in 20, if needed. As a quality-control procedure, triplicatesamples from 2 volunteers were labeled identically to the survey samplesand included in the samples shipped to the laboratory. The CVs for thesetriplicates were 1.23% and 0.71%. Population median UICs were usedto categorize population iodine intakes as insufficient (<100 mg/L),adequate (100–199 mg/L), above requirements (200–299 mg/L), orexcessive ($300 mg/L) (11).
