A detector assembly and method of detecting the presence of a biomarker, such as bilirubin, in a sample of a flowable substance and a detector unit () are disclosed. The method comprises providing a receiver body () shaped to define a receiving chamber (). The receiving chamber () has an outlet opening () through which a flowable substance can leave the receiving chamber (). The receiving chamber () has a maximum capacity for holding a volume of the flowable substance. A quantity of the flowable substance is supplied to the receiving chamber () and caused to pass through the outlet opening. The receiver body () can move relative to a guide () of the receive body () from a first position in which the outlet opening () is blocked to a second position in which the outlet opening () is not blocked. In the second position, a metered quantity of flowable substance in the receiving chamber () can leave the receiving chamber ().

Method of detecting the presence of a biomarker in a sample of a flowable substance, a detector assembly for use in the detection of a biomarker in a sample of a flowable substance and a detector unit for use in the detection of the presence of a biomarker in a sample of a flowable substance

In the detection of the presence of a biomarker or the like in a sample of a flowable substance, e.g. a powder or a liquid, usually a body fluid, such as blood, urine, or saliva, for example, a disposable sample receiver () is used, which has a receiving chamber () that is dimensioned to receive a predetermined volume and is surrounded by a depression () receiving any excess volume for which there is no room in the receiving chamber (). The receiving chamber () has a bottom outlet () closed by a removable strip (), e.g. a plastic strip or foil. Upon pulling away the strip () from the bottom outlet, the sample in the receiving chamber is emptied into a flow path () leading to at least one detection compartment () permitting direct visual inspection. Preferably, disposable sample receiver () is used in a detector assembly () including an electronic camera (), a CPU () and a display (). Hereby, the volume of the sample to be analyzed will always be the same, and by controlling the exact point of time when the sample is passed on into the flow path (), a high degree of repeatability and accuracy is achieved, and thereby also a fail-safe system.
