Russian scientists learned to perform the diagnose by analyzing saliva

(Peter the Great Saint-Petersburg Polytechnic University) Researchers of Peter the Great St. Petersburg Polytechnic University (SPbPU) within the framework of the Project 5-100 developed a unique method of immune diseases diagnosing before the symptoms appear. Scientists proposed a laser-correlation spectroscopic technique (also called dynamic light scattering) for studying the immune response in body fluids, for example, in saliva.
