Why should you choose a rapid test?
A "rapid test" allows you to make a cost-effective and quick therapy decision on the spot, without your patients having to wait for a second appointment.
Why is the immunological response important?
An immunological response is triggered when immune system molecules encounter foreign substances or organisms, commonly known as antigens. The immune system responds by producing specific immune cells as well as specific antibodies. The formation of a specific antibody makes it possible to bind the specific antigen.
Why a "Lateral Flow Immunoassay"?
Usingt the specific antibody (key), the antigen (lock) can be bound according to the lock–and key principle and the presence of the antigen can be indirectly visualiszed by a colour molecule on the antibody. The antigens migrate in the liquid flow towards the specific antibody. A color molecule is located at the base of the antibody. When an antigen has bound to an antibody, the antigen-antibody complex move with the fluid flow to the test line and is held there by a second specific antibody. The coloured molecules gradually cause the test line to appear. The rest of the sample moves on to the control line. The binding of the antigen-free antibodies also makes this line visible. In this format, the antigen lies between 2 antibodies (sandwich assay).
