The key difference bcrwecn the 1986 cri1eria and 1hc 200,t
cn1eria is Lha1 the 2004 Guideline pre 01 a more e plici1 ap-
proach 10 diagnosi. based on criteria: the n<!ed 10 e.1nblish e,-idence
for exposure, 10 identif • a di order compa1ible with asbc 1os as
a cause, e clusion of 01her cause . and a forceful requiremen1
for assessing impairmen1 in the event that the ph
ician makes
a diagnosis of nonmahgnan1 asbe tos-relatcd disease. Although
these elements were mentioned in 1986, they were no1 given the
same emphasis.
