'non-agglutinogenic' originates from the prefix 'non-' meaning 'not', and 'agglutinogenic', which is derived from 'agglutination' meaning 'clumping together', and the suffix '-genic' meaning 'producing or causing'.

'Agglutinogenic' changed from the Latin word 'agglutinare', meaning 'to glue to', and eventually became the modern English word 'agglutination'.

Initially, it meant 'not causing clumping', and this meaning has largely remained the same in modern usage.
