I would try to test more - change labs if necessary. Many of the tests are poor performed and there are small changes that one test will show you the culprit.
I would be careful with supplementing now with minerals multivit etc until you get them out. It could make them stronger.
See some post here and start with diet. watch your diet less refined food milk cream Sugar bread pork if you eat that. That should make them weaker and then you can try cleanse.
