Distribution of TSH levels by sample type. TSH levels for 516 infants screened by heel-prick and 1126 infants screened by cord blood. a TSH levels were 6.64 ± 4.43mLU/L for heel-prick samples, and 3.73 ± 10.58mLU/L cord blood levels (mean ± SD). Screening thresholds to identify infants requiring follow-up used in Ontario, Canada (17 mLU/L) and previously reported for pilot CH screening programs in Bangladesh (20 mLU/L, Hasan et al. 2008 [2]; and 10 mLU/L, Rasul et al. 2009 [9]) are indicated. b Correlation of TSH levels measured in 476 paired heel-prick and cord blood samples, Spearman R = 0.22 (95%CI 0.13–0.31). c Distribution of TSH values by timing of sample collection. TSH values below zero represent those that were below the detection limit of the assay
