[Evaluation of the effectiveness of substance for diagnosing rotaviral infection under field conditions].

A universal mathematical approach (algorithm) to assessment of the efficacy of new preparations for the diagnosis of rotavirus infection, analysis and processing of the results involves assessment of the detection rate of infection, specificity of preparations, probability of positive and negative diagnoses, total index of coincidence of results of diagnosis with the reference method, and chi 2 and phi2 coefficients indicating the reliability of relation to the reference method and the strength of this relation. Diatest software is proposed for accelerating statistical processing of the results. Use of the algorithm and software permits assessing the efficacy of diagnostic agents for rotavirus and other infections.
