If your lung volumes tests are properly performed, the TLC value that is above 80% of your predictive value would be considered normal. The Diffusion capacity is to be above the range of 75% of any predicted value and is considered normal.
It is important to understand that one should not smoke at least 8 hours prior to the test, avoid your caffeine intake for at least 12 hours and also avoid eating around 3 hours before your test. It is important to take medications as it has been instructed.
