What tests are done to diagnose ALS?

These typically include an MRI (magnetic resonance imaging) of the neck, and sometimes of the head and lower spine, an EMG (electromyography) which tests nerve conduction, and a series of blood tests. Sometimes urine tests, genetic tests, or a lumbar puncture (also called a spinal tap) are also necessary.

Are CK levels elevated in ALS?

Raised serum CK concentrations are also found in ALS patients. In the present study, 43% of ALS patients had a CK concentration above the upper limit of the normal range. This is consistent with previous studies that reported 23–70% of ALS patients could have raised CK levels (2, 3, 5–10).
