[The detection and investigation of traces of biological origin by cytological methods]

Thirty-four expert evaluations are analyzed in 1993-1996, in which trace particles of animal origin were pieces of material evidence. The presence of cells was certified and their species, group, and organ tissue appurtenance identified. Expert potentialities depending on the time when the object of study was formed and type of examined tissue are discussed. Combined use of biological and cytological methods permits an informative expert conclusion in cases when the traditional biological methods fail.
