Abstract

A system and method for performing an assay for target analytes includes a sampling-device holder interface and a quantifier. The sampling device has a sampling portion and a reading portion containing a chemiluminescent reagent. The interface has a sampling-device holder and a light detector. The holder has a housing having an enclosure with a channel and a base plate with an opening. The base plate and the enclosure houses a slidable tray. The tray has a compartment adapted to seat the sampling device and an opening extending through the compartment. The reading portion is aligned with the tray opening. When the tray is closed, the tray opening is also aligned with the base plate opening, exposing the reading portion. Once the sampling portion is exposed to a sample suspected of containing the target analyte, at least one carrier liquid is introduced, if needed, to the sampling portion to transport any target analyte to the reading portion by dispersion. To measure the emitted light, the sampling device is seated into the tray. The tray is then inserted into housing. The light detector, which is connected in close proximity to the reading portion, outputs a signal. This signal is then converted to quantifiable data indicative of the target analyte quantity, using for instance, an ammeter.
