Screening after preventive treatment



I had a positive PPD (Tuberculosis skin test) when I was 18, but I think I was exposed when I was much younger. I have had chest x-rays done and everything is fine. Then, last year I did the INH prophylaxis treatment. Am I still supposed to have screening done? Can I get another skin test done? Thanks!
