A method for performing a dilution step in a blood testing apparatus of a small, defined volume of a blood sample contained in a capillary tube, comprises the steps of providing an adapter for receiving the capillary tube, connecting the adapter to a conduit for diluting liquid, directing a flow of diluting liquid through the conduit and the adapter and at least partly through the capillary tube received therein, and collecting the defined volume of blood sample and the diluting liquid in a vessel. In a blood testing apparatus adapted for performing dilution of a small defined volume of a blood sample contained in a capillary tube, an adapter is inserted in a diluting liquid conduit of the apparatus. The adapter is arranged to receive the capillary tube such that flow of the diluting liquid through the conduit passes at least partly through the capillary tube.
A method for performing a dilution step in a blood testing apparatus of a small, defined volume of a blood sample contained in a separate capillary tube having open ends, comprising the steps of:
A blood testing apparatus adapted for performing dilution of a small defined volume of a blood sample contained in a separate capillary tube having open ends, said apparatus including a diluting liquid conduit and an adapter insertable in said diluting liquid conduit between a relatively upstream portion and a relatively downstream portion thereof, said adapter being arranged to receive said capillary tube such that flow of diluting liquid through said diluting liquid conduit passes at least partly from said relatively upstream portion through said capillary tube to said relatively downstream portion, wherein said adapter includes a stationary part provided with first and second connecting means for connection to said diluting liquid conduit, and a moveable part provided with receiving means for said capillary tube and being attachable to said stationary part in a position enabling flow of diluting liquid at least partly through said capillary tube.
