Blood and cerebrospinal fluid were drawn at the same time, from patients at the Neurological CHnic of Goiânia-Goiás. 49,07 % of the serum tests gave positive reactions for dilutions of 1/1.024 or higher; 26,99% for dilutions of 1/16 to 1/256; 23,92% were negative. In cerebrospinal fluid 44,78% revealed negative results whereas 52,21% were positive in different concentrations: undiluted and in dilutions of 1/4, 1/16, 1/64 and 1/256. It is concluded that the indírect immunofluorescence test in indiluted cerebrospinal fluid should be included as a routine method for the investigation of toxoplasmosis. Results should be expressed as: Positive -l- to -l--l--l--l- depending on the intenstty of fluorescence.porAcesso AbertoArtigo
