The aim of this study is the behavior of Normotest (NT) values in newborns in the first 4 days of life. The study has been carried out between January, 1982, and December, 1984, at the Department of Child Health and Neonatal Medicine - School of Medicine - University of Genoa. The number of infants tested was 1320. 694 were males and 626 females, 529 preterm (G.A. less than 37 weeks) and 791 full term babies. Infants have been tested from one to five times in the first four days of life, with the first evaluation within 12 hours of life. 1215 newborns (92%) presented NT values greater than 20%, 105 babies (8%) had NT below 20% in at least one evaluation, and received Vitamin K1 (0.5 mg/kg i.m.) as prophylaxis, being thereafter excluded from this study. Among the neonate with NT greater than 20%, 426 babies have been considered, who had, at least, three evaluations in the first four days of life. 288 (68%) of the 426 newborns, had not important disease, while 138 (32%) were sick neonates; of these babies 88 (64%) had respiratory distress syndrome and 50 (36%) had an infectious condition. The mean of NT values of the 426 newborns decreased from the first (33.84%) to the 2nd day (32.72%), with a following increment in 3rd (35.29%) and 4th day of life (39.01%). Newborns with gestational age (G.A.) less than 34 weeks showed significantly lower values than newborns with G.A. between 34-37 weeks and those with G.A. greater than 37 weeks. No newborn with NT values greater than 20% either received vitamin K or showed symptoms of haemorrhagic disease in early or later neonatal period.
