摘要

Determining a cell-bound analyte in a liquid sample comprises using a device comprising a sample delivery zone, a porous membrane with an indicator zone having a binding element for the analyte, and an absorption zone for absorbing liquid that has passed through the indicator zone. An independent claim is also included for a device as above having at least two indicator zones.
