A sample testing device ( 100 ) for testing for the presence of a component of interest in a liquid sample comprises: (a) at least one capillary pathway ( 120 ) which has an upstream end and a downstream end and which incorporates a reagent system capable of causing agglutination with said component to be detected (the test capillary); (b) preferably, but optionally, at least one capillary pathway ( 121 ) having an upstream end and a downstream end (the control capillary); (c) a sampling region ( 114 ) to which the liquid sample is applied and from which the sample is able to enter the upstream ends of the test capillary(s) ( 120 ) and if present the control capillary(s) ( 121 ); (d) a power source ( 108, 109 ); (e) detection arrangements ( 117, 118 ) electrically associated with said power source ( 108, 109 ) for detecting the presence of liquid at a downstream region of said testing capillary(s) ( 120 ) and if present the control capillary(s) ( 121 ); (f) display means ( 113 ) operated by said power source ( 108, 109 ) for indicating the result of the test; and (g) signal processing means ( 112 ) associated with the power source ( 108, 109 ), detection arrangement ( 117, 118 ) and display means ( 113 ) for evaluating the result of the test and providing said result on the display means. The device may be used for a pregnancy test, more particularly for determining the presence of hCG in urine.
