Single-Fiber EMG
Single-Fiber EMG is a specialised nerve-muscle test used to help evaluate conditions affecting the neuromuscular junction, such as Myasthenia Gravis.

What is Single-Fiber EMG?
Single-Fiber EMG is a specialised nerve-muscle test used to help evaluate conditions affecting the neuromuscular junction, such as Myasthenia Gravis.
A fine needle electrode records signals from individual muscle fibres. The variability in timing between adjacent fibres helps identify problems at the neuromuscular junction.

Commonly used to help evaluate
- Suspected Myasthenia Gravis
- Other suspected neuromuscular junction disorders where RNST findings are inconclusive
How the test works
- A fine needle electrode records signals from individual muscle fibres
- The variability in timing between adjacent fibres in the same motor unit is measured
- This variability helps identify problems at the neuromuscular junction
What to expect — step by step
-
1
Before your test
Your doctor may advise on which medicines to continue or pause before this test — please ask when you book.
-
2
During the test
A fine needle electrode is used, and you may be asked to gently contract a muscle. The test can take longer than a standard EMG.
-
3
After the test
Mild soreness at the needle site can occur for a day or two. Your report is reviewed by our specialist and shared with you or your referring doctor.
Single-Fiber EMG — frequently asked questions
How is Single-Fiber EMG different from a standard EMG? +
It looks at the timing between individual muscle fibres rather than the whole muscle, which makes it more sensitive for detecting neuromuscular junction problems.
Do I need an appointment, or a doctor’s referral? +
An appointment is best so the room and the technologist are free when you arrive — call us or book online. A referral letter helps us prepare, but you may also come to us first and our neurologist will advise which study you actually need.
How should I prepare? +
Your doctor may advise on which medicines to continue or pause before this test — please ask when you book.
What happens during the test? +
A fine needle electrode is used, and you may be asked to gently contract a muscle. The test can take longer than a standard EMG.
What happens afterwards, and when is the report ready? +
Mild soreness at the needle site can occur for a day or two. Your report is reviewed by our specialist and shared with you or your referring doctor.
