ANCA stands for which antibodies?

Explanation:
ANCA are autoantibodies that target components in the cytoplasm of neutrophils. The name literally means Anti neutrophil cytoplasmic antibodies, reflecting their cytoplasmic targets. Clinically they’re associated with small-vessel vasculitides and show characteristic patterns on testing (cytoplasmic or perinuclear) corresponding to different neutrophil antigens like proteinase 3 and myeloperoxidase. The other phrasings aren’t correct because they refer to nuclear or endothelial targets, rather than cytoplasmic ones, which is why the standard term is anti neutrophil cytoplasmic antibodies.
