Abstract: An immunoassay method for the detection or quantitation of an analyte suspected of being in a solution comprising: (a) combining said specimen, a first binding component, insoluble particles, and second binding component labelled with a signal generating material in a solid phase retention and separation apparatus having a sufficient pore size such that said particles are trapped within said filter yet permitting rapid passage of fluid therethrough in such a manner that an immunological reaction occurs if analyte is present in said specimen, resulting in the formation of an immunocomplex of insolubilized first binding component:analyte:second labelled binding component on or within said filter means; (b) separating bound from unbound material; and (c) determining the presence and/or amount of signal produced which is correlative with the amount of analyte present in the solution.

Abstract: The invention provides an imaging immunoassay detection apparatus system and method capable of detecting multiple light emitting reactions from small volume samples simultaneously and quantifying the same.

Abstract: The present invention relates to an interactive medical laboratory specimen testing apparatus system wherein a diagnostic apparatus is used in performing a diagnostic routine on a specimen. The apparatus has a single user activated switch for causing automatic dialing of a source of assistance remote from the diagnostic apparatus through a predetermined telephone number when the switch is activated to enable the user to communicate with the source of assistance through a speaker and a microphone on the diagnostic apparatus so that interactive communication with the source of assistance can be had regarding the diagnostic apparatus and the routine to be perfomed. A keyboard on the apparatus allows certain data regarding the performance of a test and operation of the apparatus to be transmitted to a remote location for analysis.

Abstract: The present invention relates to an improved diagnostic device for analyte assay which has a cylindrical body portion and a removably attached cap. The cap has a liquid inlet extending into the cylindrical body portion and has a conical shaped portion leading to a liquid discharge aperture formed therein. A pre-filter may be formed either in the liquid inlet or in a pre-filter container which can be used with the device. The pre-filter container has a substantially cylindrical body which conforms to and can be inserted in the liquid inlet forming part of the removable cap. The container has an open upper end and an associated removable closure, a bottom end sealed with a frangible material and, if desired, a pre-filter positioned in the container between the upper and lower ends.

Abstract: This invention relates to a device for testing a specimen comprising a liquid input means having a receiving inlet and a discharge aperture, filter means positioned below the input means having at least one reaction zone for receiving liquid from the input means and at least one peripheral zone associated with the at least one reaction zone, absorbent means associated with only the peripheral zone of the filter means, and retainer means for holding the filter means in position below the liquid input means such that the at least one reaction zone receives liquid therefrom.
