Epilepsy Monitor Can The Medication, Keppra, Used To Treat Epilepsy, Now Be Tested And Monitored By Drawing A Blood Level?

Can the medication, Keppra, used to treat epilepsy, now be tested and monitored by drawing a blood level? - epilepsy monitor

If Keppra was approved to treat epilepsy and convulsions, was not in the system of the patient to continue a level in the blood. I think it was because, as they are metabolized. I recently said it was possible to keep to a level equal to Keppra. I do not know whether it is a measure of blood, urine levels, etc. Any help? My 13-year-old son suffers from cerebral palsy (severe) and was treated successfully (until recently) with Keppra. Thank you!
