The body's defences and immunity – how strong is our immune system?


The immune system is our body’s defence system. When malicious „micro-organisms” such as
viruses, bacteria, fungi or parasites penetrate our body, they can cause diseases or changes inside the body. The immune system is a complex network.

It has natural barriers that hinder the penetration of germs.
For example, they include:

  • the skin with its normal flora
  • the function of the mucous membranes
  • tear fluid, which transports harmful substances away from the eyes
  • the respiratory tract, whose cilia help to remove invading germs
  • the oral cavity with its enzymes
  • the stomach with its acid and enzymes that destroy nearly all bacteria and micro-organisms
  • the bowel with its flora and the urinary tract, which filters and excretes toxic substances

The cells of the immune system circulate in the blood vessels and lymphatic vessels. If pathogens penetrate the body, the body’s own defence cells can fight them.
However, If a pathogen succeeds in crossing one of the body’s mechanical barriers (skin, oral cavity, stomach acid, etc.), the body begins its immune response. Whether or not a person actually becomes ill depends on whether they have a fully functioning immune system.
The white blood cells (leukocytes) render the pathogens harmless to the rest of the body. The individual subgroups of leukocytes have various functions within the immune system.

Respiratory tract infections occur at all times of the year and are among the most common diseases in humans. Cough, sneezing and throat pain are experienced as bothersome disease symptoms. In the course of a year, many demands are made of the human immune force. The immune system is a very sensitive network in the human body.

The basis for a healthy immune system is a balanced diet containing sufficient amounts of minerals (iron, zinc, selenium) and vitamins, adequate sleep, little stress, a lot of movement, toughing up the body (e.g. sauna) and a healthy degree of sunlight (for vitamin D formation). Malnutrition, regular alcohol consumption and smoking, constant stress, a lack of exercise and lack of sleep can considerably impair the function of the immune system. Unfortunately, the mere process of ageing frequently results in a loss of minerals as well, leading to a weakening of the immune system, to repeated infections and to the chronification of diseases.

A targeted, supplementary supply of individual minerals, nutrients and vitamins can help to strengthen the immune system.

In order to better assess the strength of our immune system, it is possible to carry out a wide variety of laboratory tests.

The laboratory tests your immune system. Your doctor will be glad to advise you.


Basic tests

  • C-reactive protein (CRP)
  • Full blood count
  • Protein electrophoresis


  • Immunoglobulin A (IgA)
  • Immunoglobulin G (IgG)
  • Immunoglobulin M (IgM)

Cellular defence

  • All immunologically important cells, including subtypes of T lymphocytes and B lymphocytes

Complement system

  • CH 50
  • Complement C3
  • Complement C4

Vitamins and trace elements

  • Vitamin C
  • Selenium
  • Zinc
  • Vitamin D
  • Iron
  • Vitamin B12
  • Determining holotranscobalamins as an early marker of vitamin B12 deficiency
  • Folic acid
