Phenotyping of cells involves loading a biological sample into a microfluidic device (1, 100) comprising cell compartments (20, 120) to capture biological material, including target cells, in the sample in the cell compartments (20, 120). A subset (20A)ofthe cell compartments (20, 120) is identified as comprising target cells exhibiting target phenotype characteristic(s) as determined based on monitoring biological material in the cell compartments (20, 120)prior to addition of a test agent. The biological material is exposed to a test agent and a phenotypic response of the target cells to the test agent is determined based on monitoring target cells in the identified subset (20A)of the cell compartments (20, 120). The phenotyping of the target cells is thereby not overshadowed by the response of other cells and non-cell material present in the biological sample. |
