“…Both are known to be affected by changes in alveolar vol ume (Va). When Va decreases, TLC0 also de creases linearly, but Kc0 increases expon entially [2,9,12,14,16,17,20,21], This makes the interpretation o f these parameters difficult in patients with re duced lung volume. Recently our group [10] has developed a correction coefficient, Z, o f transfer factor, which allows correc-tion of TLco according to the alveolar volume in which the test is performed.…”

We studied the discriminative power of the transfer factor (TL_C0), K_co(TL_C0/V_a) and Z_co (a corrected TL_co according to alveolar volume measured (V_a), introduced by our group), in order to differentiate diffuse interstitial disease from other restrictive diseases. Measurements were taken in 46 subjects, divided into two groups: Pure restriction (group 1: normal subjects with voluntary restriction and diseased subjects) and (2) diffuse interstitial restriction (group 2). There were no statistical differences in V_a between groups 1 and 2. TL_C0 was statistically lower in groups 1 and 2 in comparison with the control group (normal values of our laboratory in test with V_a > 90% of predicted) and showed a significant difference when group 1 was compared with group 2. Similar results (but with higher values than those of the control group) were found for K_co. A similar difference exists in Z_co only when group 2 is compared with group 1 but not when group 1 is compared with the control group. The corrected diffusion capacity Z_co yields the highest discriminative power
