'antialbumin' originates from modern scientific English formation, combining the prefix 'anti-' (from Greek 'antí' meaning 'against') with 'albumin' (from Latin 'albumen' meaning 'white', used for the protein).

'albumin' comes from Latin 'albumen' (meaning 'white') through Medieval/Scientific Latin into English as 'albumin'; the prefix 'anti-' comes from Greek 'antí' and in modern scientific usage has been attached to form 'antialbumin'.

Initially the elements signified 'against' + 'white' (Latin 'albumen'), but in modern use the compound specifically denotes an agent or antibody directed against the protein albumin.
