[Screening by the method of radioimmunologic analysis]. / Skrining metodom radioimmunologicheskogo analiza.

To simplify the technique of radioimmunoassay, rubber holders were used that held the test tubes when the solid phase was washed with flow water. Instead of hermetically sealing the test tubes during incubation of the test samples and labeled antiserum, the authors have placed the samples in a polyethylene bath with wet cloth.

[A comparison of the radioimmunologic and immunoenzyme methods of detecting HBsAg]. / Sravnenie radioimunologicheskogo i immunofermentnogo metodov vyiavleniia HBsAg.

The frequency of HBsAg detection by these two methods is similar, but only half of positive results is confirmed by both methods. This discrepancy appears to be explained by inadequate technology of the reagent preparation or by impossibility to rule out false-positive results. Combinations of highly sensitive methods for HBsAg indication are recommended for clinical diagnosis of hepatitis B.
