A system and method for detecting a target analyte includes a sampling device, a holder, a light source, a light detector, and a quantifier (ammeter). The device has reading and sampling portions connected by a transfer portion. The holder has a housing, including a tray, which has a compartment adapted to seat the sampling device and an opening extending therethrough, slidable therein. The sampling portion is aligned with the tray opening when it is seated. When the tray is closed, the tray opening is aligned with the light detector and the light source. Once the sampling portion is exposed to a sample, carrier liquid is introduced to the sampling portion. While the carrier travel to the reading portion, the target analyte picks-up a labeling luminescent agent contained in the transfer portion. The reading portion captures the labeled target analyte. The non-captured elements exits the reading portion, leaving only the target analyte bound to the luminescent agent, which glows when exposed to light. To quantify the emitted light, the sampled device is seated into the tray and moved into the holder, whereupon the reading portion is exposed to the light source. The light detector reads the light emitted by the sample and generates a signal. This signal is then converted to quantifiable data indicative of the target analyte quantity, using for example, an ammeter.
