Good Day My Husband Got His Xray Result And His

good day my husband got his xray result and his result stated :roentgen finding fibronodular densities are noted in both upper fields impression ptb both upper probably stable. suggest comparison with previous film for stability. I remember his prev xray and it was normal but we didnt keep the old film. Is there other test to know if he really has ptb? please help us cause he needs it for employment abroad. thank you
