Can anyone give me a list of the BAD bacteria/gut bugs our kids need to be tested for? My friend is at her pediatrician right now and needs to know so she can get the right tests ordered for stool test. Her son has had runny stools for a couple months now. They have been seeing Dr G and he says testing not necessary, just to have her son keep taking Miralax, Benefiber, and make sure his diet is perfect (which it always has been)
