Tiempo de lisis de euglobulina - Overview

Nombres alternativos

Lisis de euglobulina en coágulo; Lisis de euglobulina/fibrinólisis; TLE

Definición:

Es un examen de sangre con el que se observa qué tan rápido se descomponen los coágulos en la sangre.

Forma en que se realiza el examen:

Se necesita una muestra de sangre. Para obtener información sobre la forma como se hace esto, ver el artículo: venopunción.

El especialista del laboratorio hará pruebas en la muestra de sangre para ver con qué rapidez se disuelven los coágulos sanguíneos. La disolución de los coágulos de sangre se denomina fibrinólisis.

Preparación para el examen:

No se necesita preparación especial para este examen.

Lo que se siente durante el examen:

Cuando se inserta la aguja para extraer la sangre, algunas personas sienten un dolor moderado, mientras que otras sólo sienten un pinchazo o sensación de picadura. Posteriormente, puede haber algo de sensación pulsátil.

Razones por las que se realiza el examen:

Este es uno de los mejores exámenes para diferenciar la fibrinólisis primaria de la coagulación intravascular diseminada.

El examen también puede ser empleado para controlar pacientes que están con terapias de estreptocinasa o urocinasa para IM agudo (ataque cardíaco).
