Abstract

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 (1) are disclosed. The method comprises providing a receiver body (2) shaped to define a receiving chamber (3). The receiving chamber (3) has an outlet opening (5) through which a flowable substance can leave the receiving chamber (3). The receiving chamber (3) has a maximum capacity for holding a volume of the flowable substance. A quantity of the flowable substance is supplied to the receiving chamber (3) and caused to pass through the outlet opening. The receiver body (2) can move relative to a guide (10) of the receive body (2) from a first position in which the outlet opening (5) is blocked to a second position in which the outlet opening (5) is not blocked. In the second position, a metered quantity of flowable substance in the receiving chamber (3) can leave the receiving chamber (3).
