How Strong is Your Immune System?
Test your immune system now to get early indications of severe COVID-19 disease!
Studies show a significant reduction of immune cells in the blood of patients with severe courses of COVID-19 disease.
The decrease in immune cells may provide an early indication of severe COVID-19 disease progression (see selected publications at the bottom of this page).
Determine your immune status now to respond in a timely manner in the event of SARS-CoV-2 infection.
T, B and Natural Killer (NK) cells are the central fighters of our immune system.
Together they are also called lymphocytes.
In severe courses of COVID-19 disease, there is a significant reduction of T, B, and NK cells in the blood
Evidence of lymphocyte reduction ("lymphopenia") may indicate early deterioration of COVID-19 disease (see selected publications at the bottom of this page).
