Will the combination of TLNO (transfer factor for nitric oxide) and TLCO be more useful in pulmonary function testing than TLCO alone?

Hot topics
Chairs: C. Hsia (Dallas, United States of America), A. T. Dinh-Xuan (Paris, France)
Aims: This session will explain why the CO transfer test (TLCO) is well known and, along with spirometry and lung volume measurements, forms the core of pulmonary function testing. The addition of TLNO to the TLCO test, in the same single breath manoeuvre, is new and used only in a few centres. This combined transfer test is likely to enhance the value of the TLCO alone. This session will bring the audience up-to-date with this new development in pulmonary function testing; one which they may wish to establish in their own laboratories.
