In this paper we prove by entirely elementary means a very effective version of the Hilbert irreducibility theorem. We then apply our theorem to construct a probabilistic irreducibility test for sparse multivariate polynomials over arbitrary perfect fields. For the usual coefficient fields the test runs in polynomial time in the input size.
