title: [Preliminary observation of determination of antibodies to tuberculosis in body fluid with solid phase radioimmunoassay].
abstract: The determination of PPD-antibody in specimens of 42 blood, 16 cerebrospinal fluid and 31 pleural cavity fluid from tuberculosis patients and the blood specimens of 160 donors were carried out with solid phase radioimmunoassay (SPRIA). The positive rates of their PPD antibodies were 90.5%, 68.8%, 77.4% and 5% respectively. The positive rates of same specimens determined with ELISA assay were 50.0%, 38.5%, 40.9% and 6.3% respectively. SPRIA is as specific as ELISA, but the former is more sensitive than the latter.
