Table 1.
Group means (range) for TH values for CH and mothers of HYPO.
| CH (N = 25) | HYPO (N = 17) | |
|---|---|---|
| Trimester 1 TSH value (mU/L)a (Normal range during pregnancy<2.5mU/L) | – | 9.76 (.10–28.11) |
| Trimester 2 TSH value (mU/L)b | – | 7.38 (.45–38.50) |
| Trimester 3 TSH value (mU/L)c | – | 4.90 (.10–17.60) |
| TSH value at birth (mU/L)d (Normal range=.4–4.1mU/L) | 135.00 (20.00–250.00) | 4.54 (1.50–12.60) |
| TSH value at diagnosis (mU/L)e | 352.75 (9.10–1172.80) | – |
| Total T4 value at diagnosis (nmol/L)f (Normal range=50–150nmol/L) | 72.21 (5.00–229.00) | – |
| Free T4 value at diagnosis (pmol/L)g (normal range=10–23pmol/L) | 8.93 (1.40–21.30) | – |
| Age at diagnosis (in days)h | 42.75 (5.00–730.00) | – |
Note: TSH = thyroid stimulating hormone, higher TSH levels indicate more severe TH.
Deficiency, T4 = thyroxine.
