Abstract: The present invention relates to an arrangement for collection and separation of a body fluid, e.g. whole blood, for purposes of analysis of a component, e.g. plasma, of a sample of the body fluid. It comprises means for receiving a body fluid, a filter arrangement (50) comprising a separation filter arrangement for separation of the component(s) to be analysed and a detection filter in communication with the separation filter arrangement. The filter arrangement comprises a pre-filter (6) having a filter volume adapted to be capable to receive a volume of body fluid exceeding a volume of a sample to be analysed, which comprises a first portion defining a sample zone volume arranged to form a sample zone and at least one second portion defining an excess removal zone volume, forming an excess fluid removal zone the volume of which exceeds said sample zone volume.

Abstract: The following invention relates to a device for visual detection of hemolysis in a whole blood sample from a pierceable container, said device comprising at least one visible detection compartment and a transfer passage connected to said visible detection compartment, said device further comprising means for passing through the container to the interior of said container for accessing the whole blood and permitting transfer of a volume of plasma from said sample to said detection compartment via said transfer passage, wherein said device further is arranged with a separation device for separating plasma from blood cells within said whole blood sample before said plasma reaches the detection compartment, said device further being arranged with means providing a capillary action for generating a capillary force urging said volume of plasma to be transferred through the separation device to said detection compartment.
