The mean serum level of fT 4 in our group was 14.2 (±2.9) pmol/L, range 8.1-24.4 (reference value 12-22 pmol/L) compared with 16.9 (±6.1) pmol/L in a sample of 13248 measurements at LUH, comprising all measurements in a single hospital (LUH) done during one year, and the difference was significant (p <0.001).
Meðaltalsgildi fT 4 í rannsóknarhópnum var 14,2 (±2,9) pmol/L, bil 8,1-24,4 (viðmiðunargildi 12-22 pmol/L) samanborið við meðaltalið 16,9 (±6,1) pmol/L í 13248 mælingum á rannsóknarstofu LSH á eins árs tímabili og var munurinn marktækur (p <0,001).
