Migration of the sample zone driven by capillary forces in a porous carrier strip.
Notes:
- During migration the dissolved tracer becomes distributed between capture and control zones with immobilised antibodies.
- The amount of the label compound in both zones depends on the concentration of the compound in the studied sample.
Example: The most common test of this type is the one for pregnancy.
