Disclosed are collection devices, kits, and methods for collecting and transporting one or more samples. A collection device of the present invention includes a central panel including a detachable sample strip. The sample strip has a sampling area for applying a sample on each side of the sample strip. The collection device includes two flaps, each capable of covering a portion of the sample strip that includes a sampling area. Consequently, a user is not exposed to a first sample when applying a second sample. Additionally, the sample strip can be detached without uncovering the sample strip.

Sample collection and transport devices, methods, and kits

A device for assaying biological fluids for molecules contained therein comprising a container, material situated in the container for absorbing fluid and in communication with an antibody or antigen impregnated matrix, wherein the matrix is accessible to the exterior of the container through a funnel shaped aperture in the roof of the container. Further features include a chemical drying agent associated with the container for absorbing moisture, thereby preventing inactivation of the assay reagents, and a filter situated above the antibody or antigen impregnated matrix, and in communication with the matrix through the aperture in the roof of the container. The filter removes interfering substances present in the biological fluids and provides protein blocking agents to the matrix material for decreasing the background of the assay.

Immunodiagnostic device

In response to an express need for an immunoassay device with universal applicability, which further promotes the goals of inventory reduction and simplified, less costly manufacture, a container for holding materials used in conjunction with an immunoassay, having a housing with an inside, an outside, and a top, wherein the top is provided with a plurality of apertures communicating with the inside of the housing, and a thin web of opaque material applied over the top of the housing covering at least one but not all of the apertures.

Solid phase immunoassay device and method of making same

The invention provides a disposable device for collecting, transporting and storing semi-solid or liquid specimens prior to analysis. A sample of the collected specimen is removed from the device for analysis by means of a detachable transferring stick, one area of which is the sample collecting portion of the device and another area of which is an integral handle. The device also provides for the collection of a liquid sample drained from a defined volume of a semi-solid specimen through porous screen and collected on the detachable transferring stick. A sample of the specimen or liquid from it may be flushed from the stick for a qualitative or quantitative determination of analyte. The device is useful in collecting fecal specimens and detecting occult blood therein by a determination of hemoglobin in the specimen itself or in a liquid sample drained therefrom.

Occult blood sampling device and assay

The invention disclosed herein relates to the field of one-step assays and latex agglutination tests ('LAT'), and provides an improved method of preparing and using a one-step immunoassay, as well as improved methods of preparing coated latex particles for use in diagnostic assays, and especially, immunochromatographic assays.

Immunochromatographic assay and method of using same

Disclosed is a method for detecting analytes in samples of whole blood using solid-phase, permeable support assay devices. The whole blood assays require no steps or reagents other than those necessary to carry out the same analysis on plasma or serum using the devices. The color visualization of the analytical field on which the interpretation of the assay depends is not affected by the presence of intact erythrocytes or any degree of hemolysis in the blood sample.
