'lab-based' originates from the word 'laboratory,' which comes from the Latin word 'laboratorium,' where 'laborare' meant 'to work.'

'laboratorium' transformed into the English word 'laboratory,' and eventually the term 'lab-based' was coined to describe activities or work conducted in a lab setting.

Initially, it referred to any work done in a laboratory, and this meaning has largely remained the same in modern usage.
