|Dennis, the VA told me there was no test for AO. All they did was pull out a map of Vietnam and ask me to show them where I was. Then they showed me a list of AO related diseases and ask me if I had any of them. I have lost two grandchildren to a metabolic mitochondrial disease in 2004, brother and sister from my youngest daughter. I have had severe rashes in the genital area and on my legs. I have escaped so far the more serious diseases. God Bless you.
