A sample of blood is placed on a bilirubin test strip and plasma separated from the red blood cells. The bilirubin test strip is located on a test card along with a set of calibration images, the colors of the calibration images being associated with known plasma bilirubin levels. A photograph is taken of the test card. The bilirubin level of the blood sample is determined by, within the photograph, interpolating the color of the plasma and the colors of the closest colored calibration images.

The disclosure relates to a container for filtering a suspension which comprises a lid and a vessel. The container comprises a filter that divides an interior space of the container into a first compartment and a second compartment. The lid comprises a first access and a second access. The first access is connected to the first compartment, and the second access is connected to the second compartment.

The present invention relates to a platelet testing device using blockage phenomenon, comprising: a sample chamber containing blood sample; a microfluidic tube which is in fluid communication with the sample chamber and through which the blood sample flows; and a microbead packing arranged on a flow path of the blood sample of the microfluidic tube; wherein the microbead packing comprises: a packing pipe which constitutes a part of the flow path of the blood sample; and a plurality of microbeads contained in the packing pipe and arranged to be in close contact with each other so as to form voids between the microbeads, whereby function of the platelet is tested by blockage phenomenon of the voids due to the platelet in the blood sample which flows through the microfluidic tube from the sample chamber according to the present invention.

A filter module (10) has a housing (12) which is subdivided by a membrane filter (14) into an inlet chamber (16), which is connected to an inlet connecting piece (22) arranged rigidly on the housing (12), and an outlet chamber (18), which has a filtrate outlet (20). The inlet connecting piece has two connectors, specifically a first connector (26) and a second connector (28), which connect selectively and fluidically to the inlet chamber with a 3-way valve (24) integrated into the inlet connecting piece. The valve has a first entry, which is connected to the first connector, a second entry, which is connected to the second connector, and an exit, which is connected to the inlet chamber. The first connector is configured as an adapter for outwardly sealed coupling of a culture medium bottle (30), which coupling permits a gravity-driven exchange of liquid with the first entry of the valve.
