The PPD(Purified Protein Derivative) or commonly known to us as Tuberculin Test is done to determine the presence of bacterial infection in our body...
And if the result is "negative", no further tests to be done. But if the result is positive, though it does suggest that your friend may or may not have an active TB,...he will still need to repeat a Chest X-Ray to be able for his Doctor to learn and understand its implications and decide whether your friend can be recommended for fit to work visa or not? Hope it helps :)
