What is the first test for ALS? Can blood tests show ALS?

There is no single test that can quickly identify whether you have ALS. However, Analyzing samples of your blood and urine in the laboratory might help eliminate other possible causes of your symptoms.

Serum neurofilament light levels, which are measured from blood samples, are generally high in people with ALS. Therefore, this test can help make a diagnosis early in the disease.

The exact cause of ALS is unknown, but about 10% of cases are inherited, while the rest are sporadic. Research suggests a complex interplay of genetic and environmental factors involved in the occurrence of ALS.

However, as the disease progresses, patients may experience difficulty speaking, swallowing, and performing everyday tasks. Respiratory muscles may also be affected, resulting in breathing difficulties and respiratory failure.

The risk of developing ALS increases with age and is higher for men than women. ALS can affect any part of the body, but it often starts in the hands, feet, arms, or legs.
