Hello All, Recently, my sister told me that my brother-in-law had a taken a test referred to as 'CPK' to determine the free radical count in his blood (he does not have Parkinson's but he does have an auto-immune disorder, the name of which escapes me only that it is a very long, technical name). Apparently the normal count is around 180. Has anyone heard about this test? It seems to me that if indeed people with Parkinson's are victims of overly active free radicals, this test might be informative. If Parkies were routinely tested and baselined vs. the population at large, we might see a trend starting to develop. Incidently, my brother-in-law has apparently been able to lower his 'free radicals' significantly through a regimin of herbal 'medicines'. If testing is available to quantify the effectiveness in the treatment of Parkinson's (of alternative treatments), I'm wondering why it's not utilized as well as clinical observation of symptomatic characteristics. Reactions, thoughts, facts, comments? Regards, Jeff Carper [log in to unmask] --
