How do I find out if black spots are mold?

Does anyone know where a piece of dark area after a overflow from the apt above me had flooded my floor bathroom nearly 3 years ago & has left darker looking spots on my bathroom ceiling? The landlord only painted over it, then it came through of the spots & after the painting was done, there were bubbles up on the ceiling. I would like if there is somewhere I can go to testing for mold.
