🔬 What is the Test?
The Acetylcholine Receptor (AChR) Antibodies Test detects autoantibodies that attack acetylcholine receptors at the neuromuscular junction, disrupting communication between nerves and muscles. It is a key diagnostic test for Myasthenia Gravis (MG), a chronic autoimmune neuromuscular disorder that causes muscle weakness.
📊 Normal Ranges:
Negative/Normal: < 0.5 nmol/L
Borderline: 0.5 – 0.9 nmol/L
Positive: > 0.9 nmol/L (Indicates MG or related neuromuscular disorders)
🩺 Purpose of the Test:
✅ Diagnose Myasthenia Gravis (MG)
✅ Differentiate MG from other neuromuscular disorders
✅ Monitor disease progression & response to treatment
🧪 When is it Recommended?
🔹 Unexplained muscle weakness & fatigue
🔹 Drooping eyelids (ptosis) & difficulty swallowing
🔹 Muscle weakness that worsens with activity & improves with rest
🔹 Suspected autoimmune neuromuscular conditions
📝 How is the Test Done?
1️⃣ A blood sample is drawn from a vein.
2️⃣ The sample is analyzed for AChR autoantibodies.
3️⃣ Results help confirm or rule out Myasthenia Gravis.
⚠️ What Do Abnormal Results Mean?
📈 Positive AChR antibodies: Likely Myasthenia Gravis (MG)
📉 Negative AChR antibodies: Does not rule out MG; additional tests may be needed (e.g., MuSK antibodies, EMG, CT for thymoma).
