In brief: Yes
Of course the lab would be happy to accept your money for repeat testing - but the question is why a repeat western blot.
If the elisa antibody screen is negative you do not need western blot confirmation, and if it is positive but the western blot results suggested biological false-positive results, then if you do not believe these, a PCR for viral nucleic acid is the best answer.
