THE USE OF LABORATORY PORTABLE DEVICE СRYSTALLINA TO STANDARDIZE A PRE-ANALYTICAL STAGE OF CRYSTALLOGRAPHY IN ORAL FLUID

Abstract

Objective: The study objective is to determine the effectiveness of functional laboratory device Crystallina to standardize pre-analytical stage of crystallography of oral fluid. Methods: We took oral fluid samples from 96 children aged 9-11 y.o. Saliva samples were examined with a standard method in a control group (48 people); we used the device Crystallina to examine samples in an experimental group (48 people). Results: The frequency of a standard qualitative sample of a saliva drop and facies was 90 % in the experimental group, and it was 45 %o in the control group. Conclusions: Leveling a horizontal surface with the additional equipment of Crystallina enables to take a drop of mixed saliva that meet the standards. The use of insulating cover blocks the insertion of foreign particles into the drop, and it enables to avoid artifacts. Obtained data provides evidence of high effectiveness of a portable laboratory device Crystallina to standardize a pre-analytical stage of crystallography of any biological fluid.
