Anticuerpos asociados a las plaquetas - Results

Valores normales:

Un examen negativo es normal.

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.

Significado de los resultados anormales:

Los resultados anormales muestran que usted tiene anticuerpos antiplaquetarios, que son proteínas producidas por el cuerpo que se fijan a las plaquetas y las destruyen. Esto provoca un bajo conteo de plaquetas, que puede llevar a un sangrado excesivo.

Los anticuerpos antiplaquetarios pueden aparecer en la sangre por razones desconocidas (púrpura trombicitopénica idiopática) o como efecto secundario de ciertos fármacos como oro, heparina, quinidina y quinina. Estos fármacos algunas veces pueden provocar que el sistema inmunitario identifique sus propias plaquetas como anormales o extrañas y que las ataque.

La interpretación exacta de los resultados de este examen es polémica.
