[Correlated multiple parameters in pleural effusion with pathology of pleurae for differential diagnosis of tuberculous and carcinomatous pleuritis].

The level of ADA, LZM, leukocyte count, lymphocyte in tuberculous effusion is higher than that of carcinomatous effusion (P < 0.05). All results showed that the change of multiple parameters is related to the pathological manifestation of pleurae. The false positive or negative result was influenced by pathological appearance and bloody character of pleural effusion. Using the ADA, LZM cut off value at 35U and 30mg, respectively, and pleural/serum ADA ratio > 1.4, LZM > 1.1, a sensitivity and specificity of 100 percent were achieved.
