Acetylcholine Receptor (achr) Antibody

The Acetylcholine Receptor (AChR) Antibody Test is a specialized blood test used to detect antibodies that target acetylcholine receptors at the neuromuscular junction.

These receptors play an essential role in communication between nerves and muscles. The presence of AChR antibodies is strongly associated with Myasthenia Gravis (MG), an autoimmune disorder that causes muscle weakness and fatigue.

This test helps healthcare professionals investigate suspected Myasthenia Gravis and support its clinical diagnosis.

What Does This Test Check?

• Acetylcholine Receptor (AChR) antibodies in blood

• Antibodies associated with neuromuscular transmission disorders

• Evidence supporting the evaluation of Myasthenia Gravis

Sample Requirements

• Sample Type: Serum

• Test Category: Laboratory – Immunology / Autoimmune Testing

Patient Preparation

• Fasting is generally not required, but confirm with the laboratory.

• Inform your healthcare provider about medications and ongoing treatment.

• Follow the laboratory's specific sample collection and handling instructions.

Symptoms Associated with Myasthenia Gravis

• Muscle weakness that worsens with activity

• Drooping eyelids (Ptosis)

• Double vision (Diplopia)

• Difficulty swallowing

• Difficulty speaking

• Fatigue during physical activity

Relevant Conditions

• Myasthenia Gravis

• Autoimmune Neuromuscular Disorders

Important Information

A positive AChR antibody result can support the diagnosis of Myasthenia Gravis, but a negative result does not completely exclude the condition. Results should be interpreted by a qualified healthcare professional alongside clinical findings and other investigations.

Please confirm test availability, serum sample requirements and collection instructions with the laboratory before booking.
