An assay device and method are provided which allow the determination of the presence or absence of at least one analyte in a test sample, while providing specific identification of the test subject. The assay device includes a reaction medium having at least one reaction zone and at least one control zone, which is capable of providing a pattern suitable for identifying the test subject. The pattern suitable for identifying the test subject is preferably a fingerprint. In a preferred embodiment of the invention, the reaction zone and the control zone include at least one member of a ligand/receptor pair.

A method for simultaneously processing a plural number of samples, each held in its own container and including a fluid containing particulate matter. Each of the containers with its respective sample therein is closed by a respective cover assembly comprising a pump, a filter interposed between the container and the pump, and an agitator projecting into its respective sample. Each container is engaged by a separate container receiver, each pump is engaged by a separate pump receiver, and the container receivers are moved relative to the pump receivers simultaneously to mix the samples. Thereafter all of the pump receivers are moved relative to the container receivers to operate all of the pumps simultaneously to move the fluid of each sample through its respective filter.

An apparatus and a method for separating particulate matter from a fluid, wherein the apparatus includes a specimen container, a porous arrangement positioned in a housing and suitable for collecting particulate matter in the liquid on a collection site, and a pump. The housing includes a first portion having elements that improve fluid flow through the housing and elements that decrease the porous arrangement retention characteristics of the portion. The housing also includes a portion having elements that increase the porous arrangement retention characteristics of the portion.

A biological fluid collection container comprising a cup member, a lid assembly removably mounted to the cup member comprising a housing with a downwardly extending cylindrical skirt, a luer lock with a throughgoing bore extending from one side of the lid housing. A hollow tube extends from the other side of the lid housing adjacent the luer lock and is axially aligned with the throughgoing bore of the luer lock. The hollow tube is provided with a plurality of throughgoing holes leading into its lumen along its surface to provide for a sampling along various liquid level layers of the biological fluid specimen collected in the cup member so that when the biological fluid specimen is removed from the cup member a representative sampling is obtained.

The present invention is directed to a fixative composition, the use of the fixative composition in preparing cytological or histological specimens, and a method of preparing particulate matter, such as cytology, hematology and microbiology specimens, for examination by collecting the particulate matter in a uniform layer, preferably a monolayer, and fixing the particles in a composition according to the present invention. The cytological, hematological, microbiological and histological fixative composition of the present invention contains an aldehyde crosslinker, a polyol and a detergent. The method of the present invention for preserving the particulate or histological specimen uses the fixative composition containing an aldehyde crosslinker, a polyol and a detergent.

a method for separating particulate matter from a fluid, using apparatus which includes a container and cover, a filter assembly positioned in a housing atop the cover and suitable for collecting particulate matter in the fluid on a collection surface, and a dispersing element fixed relative to the cover. The cover has a portion that is fixed in a first position and freely rotatable in a second position. The specimen is placed in the container, and a mixer apparatus rotates the container in relation to the cover to disperse the particulate matter throughout the fluid. Upon deactivation of the mixer apparatus, a fluid sample including dispersed particulate matter is drawn through the filter assembly to capture a substantially uniform layer of particulate matter on the collection surface. The housing is then opened to expose the layer of particulate matter, which is then transferred to a microscope slide.
