There is described a system for testing a sample. The system comprises a microplate, at least one actuator, a plurality of mutually spaced sensors, and a processor. The microplate has a test portion including an interactive substance. The interactive substance is inherently interactive with a specified test substance. The microplate is arranged such that at least the test portion of the microplate may be brought into contact with the sample. The at least one actuator is operable to vibrate the microplate. The plurality of mutually spaced sensors are coupled to the microplate. Each sensor is operable to provide a respective sensory data time series during vibration of the microplate. The microplate and the sensors are arranged such that the provided sensory data time series are not independent from one another. The processor is operable to receive the sensory data time series from the sensors and to process the received sensory data time series so as to provide information about the test substance in the sample based on the sensed interaction between the test substance and the interactive substance on the test portion of the microplate. A corresponding method of testing a sample is also described.
