Overview

In the prospective study cord blood samples were tested for high-sensitivity troponin T reference concentration in 454 healthy full termed newborns. The hscTnT levels in healthy newborns were significantly higher than levels in adult population (median [IQR] 38.2 [31.3–48.0] ng/l, reference interval: 20.1–83.0 ng/l). We found statistically higher hscTnT in boys when compared to girls (p=0.05). Concentrations of hscTnT were lower in newborns who underwent cesarean section than delivered vaginally (p=0.008). Furthermore, hscTnT was statistically significantly decreased in hemolytic blood samples (hemolysis level >2 g/l, p<0.05). Identified reference values of hscTnT based on this study may contribute to more precise assessment of newborns with suspicion of a myocardial disorder.
