title: [Comparative study of three presentations for research on HBs antigen by the immunoenzyme technique].
abstract: The authors present the results of a study comparing the detection of HbSAg by enzyme immunoassay using the following three different commercial kits and their corresponding apparatus: Auszyme II, Quantum II from Abbott; Enzygnost micro Elisa, Elisa Processor from Behring; Hepanostika, washer and reader micro Elisa system from Organon. The purpose of the study is to determine the sensitivity and specificity of the reaction and the extent of automation of this method. The sensitivity and specificity of the 3 kits are compared with those of a reference technique, the radioimmunoassay Ausria II, Abbott. The sensitivity of Auszyme II is equivalent to that of Ausria II and is approximately 0.2 mg/ml. The other two kits are somewhat less sensitive. The proportion of false negative is less than 1%, but with all 3 kits it is necessary to verify a negative result. The results of this study confirm the high level of sensitivity and specificity of the enzyme immunoassay for the detection of HbSAg in the serum or plasma of blood donors. This technique therefore offers an alternate method of HbSAg detection to laboratories which cannot or prefer not to use a radioimmunoassay.
