No: The prothrombin time (PT) measures if the levels of Factor 7, a protein involved in clotting, is adequate. In a neonate, all such proteins or factors, are decreased. The PT of 45s is rather high. There should be a pediatric hematologist who should see your newborn. If you are incorrectly referring to the Partial Prothrombin Time (PTT) being 45s, then that should be fine and will correct soon.
