Abstract
A fluid testing apparatus comprising a housing, a structure defining a well located in housing, a container rotatably mounted in the housing and positioned over the well. The container has a housing with a fluid flow aperture in which a filter is mounted to filter fluid passing therethrough into the well. A capillary ligand test assembly is secured to said container housing and comprises a capillary tube, a membrane strip mounted in the capillary tube and absorbent material mounted in the capillary tube adjacent the membrane strip. The membrane strip is divided into a testing zone and a control zone provided with designated ligands to capture other specific predetermined ligands.

A fluid collection and testing apparatus comprising a housing, a well positioned in said housing, a container rotatably mounted to said housing adjacent said well, said container being provided with fluid flow means for fluid communication with said well, a filter mounted in said fluid flow means to filter fluid passing into said well and a capillary ligand test assembly secured to said container.
A fluid testing apparatus comprising a housing, a well located in said housing, a container rotatably mounted to said housing and positioned adjacent said well, a cap mounted to said housing and said container, said container comprising a container housing with fluid flow means allowing fluid communication with said well, a filter mounted in said fluid flow means to filter fluid passing into said well and a capillary ligand test assembly secured to said container housing;
- said capillary test assembly comprising a capillary tube, a membrane mounted in said capillary tube and absorbent material mounted in said capillary tube, said membrane comprising a membrane strip divided into a testing zone and a control zone provided with designated ligand capture means to capture specific predetermined ligands.
A fluid testing apparatus comprising a housing, a well positioned in said housing, a container rotatably mounted in said housing and positioned over said well, a cap mounted to said housing and said container, said container being in fluid communication with said well, a filter connected to said container into said well and a capillary ligand testing assembly secured to said container housing, said capillary testing assembly comprising a conduit member with a foot adapted to cover said well, an absorbent material mounted in said conduit member away from said foot, a membrane mounted in said conduit member adjacent said absorbent member and extending to said foot, said membrane arranged as a strip divided into a testing zone and a control zone, said testing zone of said membrane strip including antibodies secured to said membrane strip.
A method for collecting and testing a biological fluid comprising the steps of:
- a). filling a first container with a ligand having a colored labelling means;
- b). filling a second container positioned adjacent said first container with the biological fluid to be tested;
- c). aliquoting said biological fluid from said second container into said first container by causing said biological fluid to pass through a filter into said first container;
- d). providing relative rotation between said first and second container cutting off biological fluid flow into said first container to provide incubations allowing the formation of said ligand complex;
- e). providing relative rotation between said first and second containers to provide said first container opposite a capillary assembly;
- and
- f). reacting said ligand complex with antigen mounted to said capillary assembly.
A method of collecting and testing a biological fluid comprising the steps of:
- a). filling a first container with a biological fluid to be tested, said first container rotatably mounted in a second container provided with a labelled antibody;
- b). aliquoting the biological fluid into the second container provided with labelled antibody to react with the labelled antibody;
- c). rotating at least one of the containers with respect to the other container to a first position to stop the flow of biological fluid from one container into the other container;
- d). allowing the labelled antibody to complex with specific antigens present in the biological fluid;
- e). rotating at least one of the containers with respect to the other container to a second position, thereby permitting the complexed antigen labelled antibody to enter a capillary assembly mounted to said first container which captures said complexed antigen labelled antibody to provide a test result.
A fluid collection and testing apparatus comprising:
- a reaction chamber;
- a collection chamber mounted in relation to and being communicable with said reaction chamber;
- and
- a capillary test assembly for indicating the presence of at least one predetermined analyte in a fluid, said capillary test assembly being communicable with said reaction chamber.
A fluid collection and testing apparatus comprising:
- a reaction chamber;
- and
- a housing operatively associated with said reaction chamber and including:
- a sample collection chamber communicable with said reaction chamber, and
- a capillary test assembly for indicating the presence of at least one predetermined analyte in a fluid, said capillary test assembly being attached to said sample collection chamber and communicable with said reaction chamber.
A kit for fluid collection and testing for an analyte comprising:
- (a) an apparatus for collecting a fluid sample and testing for the presence of an analyte including:
- a reaction chamber;
- a collection chamber mounted in relation to and being communicable with said reaction chamber;
- a capillary test assembly for indicating the presence of at least one predetermined analyte in a fluid and being communicable with said reaction chamber;
- and
- (b) at least one test reagent.
