CSF Ac Levels

The ace level in the spinal fluid is really a representative of activated macrophages. Soi won't say it's totally without value, I just think that it's not necessarily the sensitive indicator of including in nerosarcoids the cause for chronic manegitis. But if they're positive or have positive ace level, and then you treat the patient and follow them along, it's another marker that disease might be active in the spinalflu when it turns negative to positive again.
