If you are undergoing a blood drug test you are most probably fine. If you're taking urine test it would be more of a 50-50%, this because 2,3 days is normal detenction time of heroin in urine, but if you had lots...you maybe slightly above cut off level.

For an hair test it's too early, it would not be detected...if it's been the one and the only assumption.
