Should i be told i have als when all i have had for tests are blood mri and a ct scan?

Unclear.: There is no such thing as a blood mri. There mris of blood vessels (mras). Ct scans are inadequate for detection of many neurological disorders. Best course, get an EMG and nerve conduction study by a competent neurologist.

ALS workup: Als is a neuromuscular disease that takes more than tests such as "blood[, ] mri" or ct to determine. See a neurologist specializing in neuromuscular disorders to give you a comprehensive history and physical as well as emg/electrodiagnostic tests, swallowing studies or other evaluation tools to help address your needs and concerns.
