Abstract: Methods for dosing a fluid into a receiving channel of a test element using a dosing device are disclosed. The dosing device comprises a dosing chamber in fluid connection with a dosing tube having a dosing tip, an optional dosing element extending at least partially into the dosing chamber, a dosing control device, and a movement device for moving the dosing tube and the test element closer to one another. The movement device is actuated to move the dosing tube relative to the test element. The dosing control device is actuated to discharge a fluid into the receiving channel. During the discharge, a fluid bridge forms between the dosing tip and the receiving channel. At the end of the discharge, at least some of the fluid reaches the receiving channel through suction force. A disposable cartridge may be used for dosing a fluid into such a receiving channel.
