Resumen

SALABARRIA, José R. et al. Nueva formula matemática para el calculo de la proteinuria de 24 horas en niños. Rev Cubana Pediatr [online]. 1996, vol.68, n.2, pp.99-104. ISSN 0034-7531.

A mathematical formula for the quantification of 24-hour urinary protein excretion in children and adolescents, derived from the proteinuria-creatinuria relation (PCR) was elaborated. 104 urine specimens were processed and divided into two groups according to daily creatinine excretion. 24-hour proteinuria was determined in each group by the traditional method and by the formula proposed. An excelent correlation (r=0,994) and an elevated correspondence in the group with adequate urine collections were obtained, but it was not so in the group with inadequate collections (r=0,896). On comparing the PCR in 30 urine specimens collected at three different periods with the corresponding 24-hour PCR, an elevated correlation (r 0,99) was obtained; however, the one with the greatest identity was that collected between 7:00 a.m. and 12:00 m.
