Nombres alternativos

Examen de 25-OH vitamina D; Examen de calcidiol 25-hidroxicolecalciferol

Valores normales:

El rango normal es de 30.0 a 74.0 nanogramos por mililitro (ng/mL).

Nota: los rangos de los valores normales pueden variar ligeramente entre diferentes laboratorios. Hable con el médico acerca del significado de los resultados específicos de su examen.

Los ejemplos anteriores muestran las mediciones comunes para los resultados de estas pruebas. Algunos laboratorios usan diferentes medidas o podrían evaluar diferentes muestras.

Significado de los resultados anormales:

Los niveles por debajo de lo normal sugieren una deficiencia de vitamina D, una afección que puede resultar de:

  • Falta de exposición a la luz solar
  • Falta de vitamina D adecuada en la dieta
  • Enfermedad hepática y renal
  • Absorción deficiente
  • Uso de ciertos medicamentos, como fenitoína, fenobarbital y rifampina

Los niveles bajos de vitamina D son más comunes en los niños de raza negra, particularmente en el invierno, así como también en bebés que son alimentados exclusivamente con leche materna. Los niveles bajos de vitamina D también se han asociado con un aumento del riesgo de desarrollar cáncer. Para más información, ver el artículo sobre la deficiencia de vitamina D.

Los niveles por encima de lo normal sugieren que hay un exceso de vitamina D, una afección llamada hipervitaminosis D.
