Poland Syndrome, to the best of my knowledge, is diagnosed through physical appearance. i.e. malformation of one side of the body (Usually the right) and or missing muscle groups. I am not aware of any test for it. For someone born with restricted movement due to webbing of the arms, fingers or toes, then a plastic surgeon should be consulted to correct this. Otherwise, for those conscious of their physical appearance a plastic surgeon can also be consulted.
