I think we must have read different books. Deckard is a human in the Philip K. Dick novel.
An android at one point attempts to gaslight Deckard and another officer into believing they are androids and their lives are a lie, but they realize he’s lying and administer the empathy tests on themselves to prove it. IIRC, androids are also unable to use the empathy boxes of the Mercerism religion, but we see Deckard use one like everyone else.
The other angle, however, is that the novel is ultimately a story about humans who lack humanity, set against androids who give the appearance of humanity more than most humans do. Deckard is notable for being one of the few human characters in the book capable of genuine empathy, which is what causes him to wrestle with the morality of his line of work. And unlike the replicants of the movies, it’s shown that androids ultimately are not capable of empathy after all, ending a bit more like the film Ex Machina. Having Deckard be an android makes for an interesting movie twist, but it invalidates a lot of the development and messaging of the novel.














Hwæt?
