4 findings. Cover the answers and work down the list — then flip it and predict the finding from the diagnosis.
IgE cross-linking on mast cells → immediate degranulationType I
IgG/IgM against a fixed cell-surface antigen → complement/opsonisationType II
Soluble immune complexes deposit in tissues → complement-driven inflammationType III
Sensitised T-cells → delayed (48–72 h) macrophage activationType IV
