Prueba tuberculínica de punción múltiple - Results

Nombres alternativos

Prueba de la tuberculina por punción múltiple

Valores normales:

Si el resultado del examen sale negativo, el área puede presentar algo de enrojecimiento, pero no estará hinchada ni firme como la picadura de un mosquito. Esto significa que uno no ha estado infectado con la bacteria que causa la tuberculosis.

Significado de los resultados anormales:

Si uno ha estado infectado con tuberculosis, el área se tornará roja e hinchada como la picadura de un mosquito en 48 a 72 horas. Esto se considera un resultado positivo y significa que el sistema inmunitario del cuerpo detectó la sustancia inyectada bajo la piel.

Una prueba tuberculínica positiva no significa que uno tenga tuberculosis activa, sino únicamente que ha estado expuesto e infectado en algún momento en el pasado.

Se puede tomar una radiografía de tórax para determinar si uno tiene o no tuberculosis activa.

Si uno resulta positivo en la prueba tuberculínica, también debe hacerse una prueba cutánea con tuberculina.
