What is the general performance of low immunity

The immunity of the human body is provided by the immune system, whose main function is to find and eliminate "foreign" and maintain a healthy body. When human immunity is low, the following manifestations often occur:

1. Easy to feel tired and weak;

2. Easy to "get sick", more prone to respiratory tract, digestive tract and other system infections than the surrounding population;

3. Slow recovery from "illness."

If you want to assess whether you have low immunity, the initial screening can be performed by blood routine tests, which can initially assess the number of different white blood cells, taking lymphocytes and neutrophils as an example, their reduction often indicates a decline in immune function.

If a more accurate assessment of immune function is needed, T/B/NK cells and their subsets, humoral immunity and other tests should be performed. If there is a significant decrease, it indicates low immunity.
