Abstract:
In Guatemala, the reference values for neonatal screening tests are based on those calculated in a population different from the Guatemalan population. The aim of the study was to develop an adjustment in the reference values of the basic neonatal screening panel, in order to reduce false positives and avoid false negatives in altered tests, with a quantitative, retrospective and exploratory methodological design. A total of 1,304 live newborns were included, and the proposed reference values were calculated based on the non-Gaussian distribution of the population; percentiles 99, 99.5 and 99.9 were calculated. The proposed reference values according to the findings are neonatal TSH < 10 IUIU/mL, immunoreactive Trypsinogen < 63.54 ng/mL, total Galactose < 8.78 mg/dL, Phenylalanine < 2.17 mg/dL and 17 Hydroxyprogesterone values chosen based on weeks of gestation less than 32 SMG < 61.38 ng/mL, 33 to 34 SMG < 33.79 ng/mL, 35 to 36 < SMG 17.03 ng/mL, 37 to 38 SMG < 19.03 ng/mL 39 to 40 SMG < 14.45 ng/mL and with more than 40 SMG < 11.23 ng/mL. These results show the need to make adjustments to the reference values of the basic neonatal panel, based on the characteristics of the population where they are performed, such as sex, birth weight, type of feeding, weeks of gestation and type of delivery, since these are factors that influence these values.
