An exudative effusion can cause many different pathologic processes, such as bacterial infections, viral infections, neoplasms, and collagen vascular diseases. What are the typical laboratory results of an exudate?
a. Specific gravity is less than 1.015, total protein is >3.0 g/dL, a ratio of total fluid protein to serum protein is >0.5, a ratio of fluid LD to serum LD is >0.6, and a total leukocyte count usually is >1000/mcL.
b. Specific gravity is <1.015, a total protein is < 3.0 g/dL, a ratio of total fluid protein to serum protein is <0.5, ratio of fluid LD to serum LD is <6.0, and a total leukocyte count usually is <1000> c. Specific gravity is <1.015, a total protein is < 3.0 g/dL, a ratio of total fluid protein to serum protein is more than 0.5, ration of fluid LD to serum LD is <6.0, and a total leukocyte count usually is >5000/mcL.
d. Specific gravity is >1.015, a total protein is >3.0 g/dL, a ratio of total fluid protein to serum protein is >0.5, a ratio of fluid LD to serum LD is >0.6, and a total leukocyte count usually is> 1000/mcL.
