Abstract
The invention concerns a device for the qualitative or quantitative measurement of a magnetically labelled analyte. The device includes a coil arrangement for measuring the analyte from a sample absorbed in a test base. The coil arrangement includes at least one measuring coil and a reference coil arranged in connection with it. From the signal of the coil arrangement a change in inductance correlating to the content of the magnetically labelled analyte is arranged to be detected. The change in inductance is arranged to be detected from a change (ΔA, Δφ) in amplitude and/or phase appearing in the output signal of the coil arrangement, which is arranged to be measured at the frequency of the input signal. In addition, the invention also relates to a corresponding method.
