Quantitative Assessment of Immunological Level Using Peripheral Blood Cells

This year, 2020, is unforgettable in terms of COVID 19. When infected, high percentage of elderly people become severe in disease state, because they are usually immunologically low in level and have some underlying diseases. It is of note that the severe condition of COVID-19 is also observed in some of younger people. The fact suggests that immunologically deficient status may be observed in younger people. A quantitative assessment of the immune system developed by us was performed in more than 6000 people of various ages and indicated that a significant decline was observed in about over 10% of younger people without notable diseases. Major possible reasons for immunological depression in these younger people are stress and improper lifestyle.
