Respecto a la proteinuria…
1. Solamente la proteinuria de 24 horas puede ser considerada un criterio diagnóstico
2. El ratio C/P es igual de sensible que la proteinuria de 24h3. La proteinuria cualitativa solamente tiene valor cuando es positiva

¿Como tratamos la preeclampsia leve?
•Reposo relativo y dieta normal
•Control diario Pródromos, TA (~80/130-105/155)

•Control analítica/15d y fetal/semanal
•Finalización a las 38+1 semanas(HYPITAT-I)
