Prueba serológica para la sífilis (VDRL) - Results

Nombres alternativos

Batería de pruebas del laboratorio de investigación de enfermedades venéreas (VDRL)

Valores normales:

Un examen negativo es normal y significa que no se detectaron anticuerpos contra la sífilis. La prueba de detección es más probable que sea positiva en la sífilis secundaria y latente. Durante la sífilis primaria y terciaria, el resultado del examen puede ser falso negativo.

Significado de los resultados anormales:

El examen con resultado positivo puede indicar que usted tiene sífilis. Si el examen es positivo, el siguiente paso es confirmar los resultados con examen FTA-ABS, que es un examen más específico para la sífilis.

La capacidad del examen VDRL para detectar sífilis depende de la etapa de la enfermedad. La sensibilidad del examen para detectar la sífilis se acerca al 100% durante las etapas intermedias y es menos sensible durante las etapas más tempranas y tardías.

Las siguientes afecciones pueden provocar un examen falso positivo, como:

VIH
Enfermedad de Lyme
Ciertos tipos de neumonía
Malaria
Lupus eritematoso sistémico
