Morphology

lab + rat

The compound combines 'lab' (research facility) + 'rat' (the animal commonly used in experiments), so a B1 learner who knows the constituents can readily infer a creature used for testing and, by extension, a person treated as a test subject. Contextual cues (e.g., workplace or experiment settings) disambiguate the sense from the other meaning of 'rat' (informer), making the figurative human use a predictable metaphorical extension.

Etymology

Lab rat comes from the picture of a real rat in a lab, kept in a cage and watched during experiments. So when people call someone a lab rat, they mean that person feels like a 'test subject' or someone others are trying things on.
