In LOINC v2.27 the codes:
10691-4 # Mushroom.toxic identified:Prid:Pt:^Mushroom specimen:Nom:Inspection
10692-2 # Mushroom.toxic identified:Prid:Pt:Food:Nom:Microscopy.light
10693-0 # Mushroom.toxic identified:Prid:Pt:Vomitus:Nom:Microscopy.light
10707-8 # Plant.toxic identified:Prid:Pt:^Plant specimen:Nom:Inspection
10708-6 # Plant.toxic identified:Prid:Pt:Vomitus:Nom:Microscopy.light
are in the class MICRO.
Would not it be more logical that they were in Toxicology?
