Abstract:

The article shows the possibilities of improved version of quantitative absorption-elusion reaction (QAER) developed for determination of the blood traces’ group specificity on material evidence when the phenomenon of antibodies block occurs. A similar technique in the form of combination of two immunological reactions, namely absorption-elusion reaction (AER) and quantitative absorption reaction (QAR), was previously used only in the performance of forensic biological examinations of discharge traces. The conducted studies have shown the high efficiency of QAER for determining the group affiliation of blood traces: out of 197 studied objects with a negative CRA result, the presence of an antigen was established in 128 objects using quantitative accounting of the absorption phase, and in the remaining 69 objects, the truth of the negative CRA result was established — the absence of a group factor.
