Question Title: ALS and CK levelForum: Neurology Forum
| |
I have had various neurological problems for years such as fasiculations and muscle tightness with negative EMG's. Recently my doc did some blood work and said that my "CK" level was 120 and that was excellent. He said that patients with ALS have elevated CK levels. He is a GP. How true is this? = 40-50% of patients with ALS have elevated levels of CK, so there is therefore an association. Since the other 50% of patients with ALS have normal CK levels it cannot be reliably quoted as a marker for the disease.
