Alexis, I think you'll find that because of the 'abnormalities' found they decided upon the sputum test and that's the reason for the reduced validity.

Whether or not the medical staff decide upon the sputum test again will be a decision for them to make at the time. If the X-Ray is clear with no abnormalities then my guess is they'll issue a new certificate without further tests.
