This test allows to measure biological age by the method of V. Voytenko, developed at the Institute of Gerontology, Academy of medical Sciences of the USSR (Kiev, 1984).
The test at the apparent simplicity issue quite valid results, because it is based on wide population studies and is builded on the principles of multidimensional mathematical statistics.
This made it possible to reduce a large number of signs of aging to a small number of generalized estimates. The test is successfully used in medicine, physiology and psychology.
