I'm really worried about my brother. We're from Pakistan and he's been diagnosed with acute lung fibrosis. Even the doctors at Sheikh Zayed Hospital can't figure out the cause. We've done all kinds of tests at the top hospitals here, but we're still in the dark. I'm wondering if there's any way to send his samples to one of the best lung and pulmonary hospitals in India for further testing? What do you think would be the best course of action?
