Non-invasive diagnostics, methods and modern hemoglobinometers

The rapid development of technologies in the field of noninvasive analysis leads to the replacement of traditional invasive diagnostic methods in medicine, which requires manufacturers of medical equipment to adapt to this trend. The emergence of non-invasive techniques can significantly affect established invasive diagnostic procedures, such as quantification of blood parameters. Goal: to analyze the existing technologies and techniques of noninvasive diagnostics. To consider methods of noninvasive blood screening using the example of a study of hemoglobin levels in human blood. To present the implemented devices. The analysis of existing methods of noninvasive diagnostics with an emphasis on quantitative determination of hemoglobin levels is presented. Models of noninvasive hemoglobinometers and the physical principles of their operation are presented. The obtained results of the work can be used to improve the devices being developed or upgraded for the determination of hemoglobin in the blood.
