METHOD OF DIFFERENTIAL DIAGNOSTICS OF OBLIGATORY FORMS OF PRE-CANCER AND MALIGNANT NEOPLASMS Russian patent published in 1998 - IPC

FIELD: oncology. SUBSTANCE: juice is taken fasting out of nail phalanx of hand. Samples of native blood 12-15 times diluted with physiological solution are prepared. Laser correlation spectroscopy of native plasma of blood are performed. For 8 min, 800000 spectra are accumulated. When in human blood plasma, particles with hydrodynamic radii 5-30 mm in proportion 35-55% are detected, obligatory form of pre-cancer in patient is diagnosed. If percentage of above-mentioned particles reaches 55% or more, malignant neoplasms in patient are stated. When other proportions of these particles are found, no diseases of the mentioned type are diagnosed. Method allows revealing and estimating changes in homeostasis. EFFECT: increased accuracy and rapidity of testing. 1 tbl
