[Evaluation of an ELISA for the serologic diagnosis of tuberculosis].
The use of an ELISA method for the serological diagnosis of tuberculosis was assessed through the study of the presence of circulating IgG antibodies to PPD in 220 serum samples. An 82% sensibility was determined in 50 serum samples from patients with pulmonary tuberculosis, and a specificity of 95.33% in 150 serum samples from apparently healthy subjects. 20 serum samples from patients with disorders other than tuberculosis were included in the study to determine possible cross reactions.
