Systems and methods for concentrating a sample and detecting an analyte of interest using a separation liquid. The system can include a sample detection container that can include a microcavity. The microcavity can include a concentrate of a sample resulting from centrifugation of the sample. The container can further include a separation liquid located between the microcavity and a supernatant of the sample located outside of the microcavity. The separation liquid can have a density greater than that of the supernatant of the sample, and an interfacial tension with the supernatant of at least 0.05 N/m. The separation liquid can be non-toxic and inert. The method can include adding the separation liquid to the sample detection container, after centrifuging the sample detection container, to displace the supernatant located outside of the microcavity from the microcavity.
