Description

Assess autoimmune activity affecting nerve-to-muscle communication

The Acetylcholine Receptor (AChR) Antibodies, Complete Profile is a blood test panel that evaluates antibodies targeting the acetylcholine receptor. These antibodies can interfere with normal signaling between nerves and muscles and are commonly associated with conditions such as Myasthenia Gravis.

This comprehensive panel includes three key antibody measurements to provide a complete assessment.

What’s Included

  • AChR-Binding Antibodies Identifies antibodies that attach directly to the acetylcholine receptor.
  • AChR-Blocking Antibodies Detects antibodies that block acetylcholine from binding to its receptor.
  • AChR-Modulating Antibodies Measures antibodies that alter or reduce receptor availability on muscle cells.

Who Should Consider This Test

This panel may be useful for individuals experiencing:

  • Muscle weakness that worsens with activity
  • Drooping eyelids
  • Double vision
  • Difficulty speaking or swallowing
  • Fatigue with repetitive muscle use
  • Suspected neuromuscular dysfunction
