Definición

Es un examen que mide el nivel de ácido cítrico en la orina.

Forma en que se realiza el examen

Será necesario que recoja la orina en su casa durante 24 horas. Su proveedor de atención médica le dirá cómo hacerlo. Siga las instrucciones al pie de la letra para que los resultados sean precisos.

Preparación para el examen

No se requiere una preparación especial para este examen. Sin embargo, los resultados son afectados por la dieta y el examen se realiza por lo regular mientras usted está con dieta normal. Solicítele más información a su proveedor.

Lo que se siente durante el examen

El examen implica únicamente la micción normal y no produce ninguna molestia.

Razones por las que se realiza el examen

El examen se emplea para diagnosticar la acidosis tubular renal y evaluar la enfermedad de cálculos renales.

Resultados normales

El rango normal es de 320 a 1,240 mg por 24 horas.

Los rangos de los valores normales pueden variar ligeramente entre diferentes laboratorios. Algunos utilizan diferentes mediciones o analizan muestras distintas. Hable con su proveedor acerca del significado de los resultados específicos de su examen.

Significado de los resultados anormales

Un nivel bajo de ácido cítrico puede indicar acidosis tubular renal y una tendencia a formar cálculos de calcio en el riñón.

Los siguientes factores pueden disminuir los niveles de ácido cítrico en la orina:

Insuficiencia renal crónica
Diabetes
Actividad muscular excesiva
Medicamentos llamados inhibidores de las enzimas convertidoras de angiotensina (IECA)
Las glándulas paratiroides no producen suficiente cantidad de su hormona (Hipoparatiroidismo)
Demasiado ácido en los líquidos corporales (acidosis)

Los siguientes factores pueden aumentar los niveles de ácido cítrico en la orina:

Dieta rica en carbohidratos
Terapia de estrógenos
Vitamina D

Riesgos

No hay ningún riesgo con este examen.
