Los niveles elevados de Proteína C reactiva (PCR) por encima de lo normal son sugerentes de padecer algún tipo de inflamación o infección bacteriana.
Puede utilizarse esta prueba para valorar la existencia de:
La proteína C es un parámetro de ayuda ya que debe usarse en combinación con otros parámetros analíticos para realizar un diagnóstico adecuado.
Estos valores de PCR son ligeramente elevados y son sugerentes de padecer una enfermedad inflamatoria.
Se puede sospechar de una enfermedad inflamatoria intestinal (Crohn, colitis ulcerosa, diverticulitis) o de enfermedades inflamatorias crónicas como la artritis reumatoide.
También algunos medicamentos como los usados en las terapias hormonales sustitutivas en la menopausia pueden hacer aumentar ligeramente los niveles de PCR.
Los valores de PCR son moderadamente elevados y se debe buscar una posible enfermedad inflamatoria o una infección bacteriana.
En el caso de las mujeres podría tratarse de una enfermedad inflamatoria pélvica.
También sería conveniente con estos valores empezar a sospechar de una infección bacteriana como la tuberculosis o la fiebre reumática.
Los niveles de proteína C reactiva (PCR) son muy elevados y sugieren la existencia de una infección bacteriana severa con una probabilidad mayor al 80%.
Los valores de PCR pueden situarse por encima de 50 mg/dl y llegar hasta 100 mg/dl lo que sugiere con mayor certidumbre aún la sospecha de una infección por bacterias.
Puede presentarse estos valores tan elevados en caso de padecer por ejemplo meningitis bacteriana o neumonía bacteriana.
Los niveles aumentados de Proteína C Reactiva en sangre pueden indicar:
Para reducir valores ligeramente elevados de Proteína C Reactiva en sangre sería conveniente tratar cualquier proceso inflamatorio que afecte al organismo, pero una serie de medidas generales pueden contribuir a bajar ligeramente sus valores:

Se consideran valores altos de Proteína C Reactiva según la gravedad los que aparecen en la siguiente tabla:
