The number of tests ordered will vary, depending on the needs of each individual case. Following is a list and explanation of the kinds of tests you may be asked to take:
Blood Test & Lumbar Puncture
Several tests are run on blood samples. These tests look for signs of infection, anemia, or other conditions. They check the levels of vital minerals or poisons, such as lead, which may cause seizures. Blood and urine tests may also be ordered to check on liver and kidney function.
If the doctor thinks the seizure might have been caused by infection or bleeding in the brain he may order a spinal tap. This procedure removes a small amount of fluid from the spinal canal so it can be analyzed.
All these tests are designed to find out whether the seizure had an underlying cause that may be treated directly.
