[Serological diagnosis of toxoplasmosis: comparative evaluation of the Sabin-Feldman, indirect immunofluorescence and complement fixation tests].

The AA. compared the indirect immunofluorescence test (IFI), with dye test and complement fixation test (CFT), used in diagnosis of Toxoplasmosis. CFT sensitivity is slightly inferior to that of dye test and IFI; the later give strictly similar results especially at medium and high titers; IFI is more readily and safety performed and easier to interpret.
