MIXED-SALIVA DIAGNOSTIC TECHNIQUE FOR ONCOLOGICAL DISEASE Russian patent published in 2011 - IPC G01N33/487 

FIELD: medicine.

SUBSTANCE: transmission coefficient of the reference and analysed mixed saliva is determined in each of the specified ranges. Further, the related transmission coefficient values are compared. If the transmission coefficient of the analysed mixed saliva makes 63%-76.5% from the transmission coefficient of the reference mixed saliva for the range 1636-1660 cm^-1, 96.0-100% from the transmission coefficient of the reference mixed saliva for the range 2100-2200 cm^-1 and 13.7-34.8% from the transmission coefficient of the reference mixed saliva for the range 3200-3600 cm^-1, an oncological disease is diagnosed. It is followed with determining a transmission bandwidth of the mixed saliva nearby the range 3200-3600 cm^-1. The wave length range with a lower boundary 2900 to 3100 cm^-1 and an upper boundary 3550 to 3650 cm^-1 corresponds to the mixed saliva parameters of a healthy person, and the wave length range with the lower boundary 3150 to 3250 cm^-1 and the upper boundary 3390 to 3410 cm^-1 corresponds to the mixed saliva parameters of an oncological patient.

EFFECT: higher diagnostic accuracy of the oncological disease at any stage, enabled continuous tracing and following of a course of the disease.
