My 13 year old son who has multiple mental health diagnoses, was also thought to have allergies. I took him to an allergist. The 100 sample test came back negative, including the control test. Then, the 13 site best was given, all negative. Then, a blood panel was done which showed contradictory results. It showed that he did not have the Pneumococcal Im (14 serotype) or the Haemophilis Influenzau B Ag in his bogy - 18 of the 23 tests were "low". What kind of specialist should I be going to dig into this and possible psyche related connections?
