ABSTRACT:
An assay result reading device for reading the result of an assay performed using a liquid transport carrier may include at least one light source capable of emitting light incident upon at least one of two or more spatially separated zones of the carrier, a photodetector so positioned as to be capable of detecting light emanating from each of the two said zones and generating signals representing the presence or absence of a fluid sample in the respective zone, and a computation circuit. The computation circuit may be responsive to the signals to calculate a flow rate for a fluid flowing along the carrier, compare the calculated flow rate to upper and lower limits, and reject the assay result if the calculated flow rate is outside the upper and lower limits.
