Anticuerpo frente a los receptores acetilcolínicos - Results

Valores normales:

Normalmente, no hay ningún anticuerpo frente a los receptores acetilcolínicos (o menos de 0.05 nmol/L) en el torrente sanguíneo.

Nota: nmol = nanomol

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:

Un resultado anormal significa que se ha detectado el anticuerpo frente a los receptores acetilcolínicos en su sangre. Esto confirma el diagnóstico de miastenia grave en personas que tengan síntomas. Casi la mitad de las personas con miastenia grave limitada a los músculos del ojo (miastenia ocular grave) tiene este anticuerpo en su sangre.

Sin embargo, la falta de este anticuerpo no descarta la presencia de miastenia grave. Aproximadamente 1 de cada 5 personas con miastenia grave no tienen signos de este anticuerpo en su sangre.
