Estudio comparativo de los niveles de procalcitonina en el plasma y las muestras de sangre seca mediante electroquimioluminiscencia (ECLIA)

DBS represent a useful tool for quantifying procalcitonin levels in pediatric population, where venous blood collection is usually difficult. The extraction of this type of blood sample, by finger or heel puncture, avoids this problem, contributing to a rapid diagnosis of this kind of infectious processes. However, method sensitivity could be improved by performing serial measurements in samples with low basal levels (lower than 0.650 ng/mL).
