The myasthenia gravis (MG) lab test is a blood test that looks for antibodies associated with MG, a condition that causes muscle weakness. It is ordered when a doctor suspects MG based on symptoms like drooping eyelids, double vision, or difficulty chewing, swallowing, or speaking.

What it measures

  • Acetylcholine receptor (AChR) antibodies — The most common antibody found in MG; a positive result supports the diagnosis.
  • Muscle-specific kinase (MuSK) antibodies — Found in some people with MG who do not have AChR antibodies.
  • LRP4 antibodies — A less common antibody that can be present in MG.
  • Agrin antibodies — Another rare antibody that may be tested in some cases.

Who it is for

A neurologist or primary care doctor typically orders this test when a patient has symptoms suggesting MG or when other tests point to a neuromuscular junction disorder.

Preparation

No fasting or special preparation is usually required. Tell your doctor about any medications you take, as some can affect the test.

Results and what they mean

Results are reported as positive or negative for each antibody, sometimes with a numerical level. A positive result does not confirm MG by itself, and a negative result does not rule it out; a clinician interprets the results along with your symptoms and other tests. This is general information, not medical advice.

Order online, choose a certified collection site in Alaska, and review results through a secure portal. No referral is required, and orders are processed confidentially. With coastal metros, inland towns, and rural counties with very different access to testing, it pays to schedule your collection in advance.
