November 12, 2016 at 9:23 am #638 DrWoellerKeymaster Margaret, I haven’t. I have some colleagues that use the MRT and they like it fairly well. Personally, I have used the Total IgG from Great Plains which works well for my patients. Dr. Woeller Author Posts Viewing 1 reply thread You must be logged in to reply to this topic.
