Amyotrophic lateral sclerosis 1
Diagnosis and Testing
How do I get tested for Amyotrophic Lateral Sclerosis?
A series of tests may be required to diagnose amyotrophic lateral sclerosis (ALS), since it may present in similar ways to other neuromuscular disorders. Studies may include:
- Electromyography (EMG): A special recording technique that detects electrical activity in muscle
- Nerve conduction study (NCS): A test that measures electrical energy by assessing the nerve's ability to send signals
- Magnetic resonance imaging (MRI): MRIs are used to rule out other disorders. Patients with ALS will have normal MRIs.
- Blood/urine samples: Used to rule out other disorders or illness that can look like ALS
- Muscle biopsy: Used to rule out muscle disease
- Genetic testing: Using DNA to test for variations in genes that are known to cause ALS
