Nonparametric analysis in the field of health protection

A technology of health protection directed to early diagnosing, prophylaxis and treating illnesses caused by patients' professional activity was developed in Samara. The technology which was called "Double Screening Test" (DST) suggests the performance of two screening tests in the conditions very close to real ones. The first test is performed at the beginning of the working day (or before a predicted stress), the other one is done at the end of the day (after the stress). On comparing the data one finds patients with higher reactivity to real loads. They are given medical aid if necessary.
