Depuración de creatinina - Risks

Riesgos:

Los riesgos de este examen son mínimos y tienen que ver con el proceso de extracción de la sangre. En muy raras ocasiones se presenta lo siguiente:

  • Sangrado excesivo en el sitio donde se toma la muestra
  • Desmayo o sensación de mareo
  • Hematoma (acumulación de sangre debajo de la piel)
  • Infección (un riesgo leve en cualquier momento que se presente ruptura de la piel)
  • Punciones múltiples para localizar las venas

Consideraciones:

Los factores que pueden interferir con la precisión de este examen son los siguientes:

  • Recolección incompleta de orina
  • Embarazo
  • Ejercicio vigoroso

Entre los fármacos que pueden interferir con las mediciones de la depuración de creatinina se encuentran: cimetidina, trimetoprima y fármacos que pueden causarle daño a los riñones, como las cefalosporinas.

El examen de depuración de creatinina se debe hacer sólo para pacientes que estén médicamente estables. Dichos pacientes pueden tener una depuración de creatinina rápidamente cambiante y por lo tanto cualquier resultado puede ser impreciso.
