Abstract: Introduction: Neonatal jaundiceisacommon cause of hospitalization. Forthisreason,wepretendtoestablish the correlation between serum bilirubin (Gold Standard), capillary bilirubin and transcutaneous method, and its usefulness to identify phototherapy requirements. Methods: We performed a prospective, cross-sectional analytical study to 80 term infants, by applying serum, hair and transcutaneous bilirrubinometry tests. We calculated Pearson correlation and coefficients, obtaining sensitivity and specificity measurement. Results: The correlation between serum bilirubin and hair is strong (Pearson correlation index = 0.985) as well as the correlation between serum bilirubin and transcutaneous test (Pearson correlation index = 0.95), with a statistically significant p-value (<0.005). The capillar bilirrubinometry resulted in 96% of sensitivity and 91% of specificity. The transcutaneous blirrubinometry resulted in 88% of sensitivity and 98% of specificity. Conclusion: We can safely use capillary and transcutaneous bilirubin measurements, as valid screening test for jaundice detection, which could prevent a significant amount of blood sampling.
