Hi, I am struggling with testing. I want to know if my son needs folinic acid for example and if he even needs the supplements I am giving him. There are so many tests, I just don't know where to start. I did the Neural zoomer test. I don't know what is best next - FRAT, OATS, Food sensitivity? I am at a loss to be honest. Then, some say dna testing is best to learn about COMP status. It is overwhelming. Where do you think I should start? He has ASD, ADHD and newly PANDAS. thx
