Method and device for detecting a ligand in a fluid

摘要

The method involves detecting a measured value for the diffusion rate of the marker (3a,3b,3c) or a complex, consist of the ligands (2a,2b,2C) and marker is bound to ligand in the fluid (1). A reference value range for diffusion rate is available, which has marker-ligands-complex in the fluid. The measuring value is compared with the reference value range and is closed as a function of the result in the presence of the ligand in the fluid. An independent claim is also included for the device for detection of ligand.
