Abstract: Disclosed is a method for determining a quantitative estimate of the length of time since conception in a female mammalian subject, the method comprising: a) providing a liquid sample suspected of containing hCG; b) measuring, by means of an assay or assay device, an analyte measurement signal, whose value is dependent upon the level of hCG; c) comparing the measured signal value to an analyte threshold, wherein said analyte threshold corresponds to a time since conception; d) providing an quantitative estimate of the length of time since conception based upon the comparison in step (c).

Abstract: Disclosed is an assay device for determining the presence and/or extent of one or more analytes in liquid sample containing a) first and second assays each comprising a flow-path having a detection zone for immobilising a labelled binding reagent, wherein detection of a labelled binding reagent at one or both detection zones is indicative of the presence and/or extent of one or more analytes; b) a shared reference zone; c) one or more light sources to illuminate the detection zones and the reference zone; d) one or more photodetectors to detect light from the detection zones and the reference zone, which photodetector/s generate a signal, the magnitude of which signal is related to the amount of light detected; and e) signal processing means for processing signals from the photodetector/s.

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.
