Clinical Info
Serous fluids: Effusions are the accumulation of clinically detected fluid in any of the serous cavities. Effusions are further separated into transudates and exudates, which aid in determining the etiology of the effusion. Transudate: Body fluid total protein measurement < 3.0 g/dL A ratio of serous fluid total protein to a concurrent serum total protein < 0.5 indicates a transudate. Exudate: Body fluid total protein measurement >= 3.0 g/dL A ratio of serous fluid total protein to a concurrent serum total protein >= 0.5 indicates an exudate. Reference: 1. CLSI.
