摘要:
The present invention provides devices and methods for facilitating the single stream recycling of toxic substance-containing products. A toxin impermeable container designed to enclose the product containing toxic substances incorporates graphic markings or radiofrequency tags to facilitate automated or manual sorting from single stream recycling processes, identification of the toxic component, identification of the person or entity recycling the toxic to allow verification and documentation of compliance with government regulations or reimbursement of a recycling deposit that may be associated with the particular product.

A system and method of diagnosing diseases from biological data is disclosed. A system for automated disease diagnostics prediction can be generated using a database of clinical test data. The diagnostics prediction can also be used to develop screening tests to screen for one or more inapparent diseases. The prediction method can be implemented with Bayesian probability estimation techniques. The system and method permit clinical test data to be analyzed and mined for improved disease diagnosis.

A serum antibody assay for assaying a serum sample is described which has diagnostic value for determining the presence of a specific serum antibody which may be indicative of an infection by a specific microorganism. The serum antibody assay has an enhanced diagnostic value because it can eliminate interference by selected cross-reactive antibodies which are directed against one or more other microorganisms to which the assay is not directed and which may be present in the serum sample with a clinically significant frequency. The serum antibody assay uses an immunologically purified fraction of antigenic material derived from the specific microorganism to which assay is directed. The immunologically purified fraction of antigenic material includes immunologically distinguishable components of the antigenic material. These immunologically distinguishable components are reactive with the antibodies to be assayed and are nonreactive with certain antibodies not to be assayed, even where these certain antibodies not to be assayed are cross-reactive with antigen from the microorganism to be diagnosed. The immunologically distinguishable components are made using an immunoadsorption method. The immunoadsorption method may be specially screened monoclonal antibodies which bind only the immunologically distinguishable components. Alternatively, the immunoadsorption method may use polyclonal antibodies which bind immunologically cross-reactive components and leave the immunologically distinguishable components unbound.

Method and test system for monitoring the status of control of ketoacidosis-prone diabetics using pseudo-kinetic methods. Pseudo-kinetic clinical information is obtained by analysis of a single blood sample in which the blood glucose level is determined along with one or more additional indicator analytes present in patient blood, serum or plasma. The additional indicator analyte(s) provide a "historical" picture of recent events within the patient relating to glucose metabolism which, when analyzed in conjunction with the blood glucose level, provides, from a single sample, a holistic view of the degree of metabollic control in the diabetic patient which is otherwise obtainable at the present time only by the much less desirable process of drawing and analyzing multiple samples over a period of time. The additional indicator analyte may be ketone bodies.
摘要:
A competitive protein binding method is provided for the determination of an analyte which is a member of an immunological pair consisting of ligand and receptor for the ligand. A chemiluminescent source is employed comprised of one or more individual members, one chemiluminescent source member being conjugated to one of the members of the immunological pair, so as to provide chemiluminescence adjacent to the site of conjugation. A quencher molecule is conjugated to a member of the immunological pair. When the members of the immunological pair bind, the quencher molecule is brought within quenching distance of the chemiluminescent source so as to inhibit the emission of light by the chemiluminescent source. The amount of analyte present in the assay medium affects the amount of binding between the members of the immunological pair which results in quenching of the chemiluminescence. By observing the light emitted from the assay medium, either from the chemiluminescent source or the quencher, the change in light emission in relation to the concentration of analyte present in the assay medium can be used to determine the amount of analyte present in the assay medium. By employing standards having known amounts of analyte, the amount of analyte in an unknown sample can be quantitatively determined.Reagent kits can be provided having predetermined amounts of the reagents, so as to substantially optimize the sensitivity of the assay.
摘要:
Methods and reagent combinations are provided for competitive protein binding assays for determining a member of an immunological pair (ligand and receptor) whereby an enzyme-ligand conjugate is employed in combination with an enzyme inhibitor, conveniently an antibody to said enzyme. When ligand is the analyte, receptor for ligand is also included in the assay medium, while supplemental amounts of receptor need not be added when receptor is the analyte. The assay is carried out in an aqueous buffered medium, normally at constant temperature, by combining in the assay medium the unknown sample suspected of containing the analyte, enzyme-bound-ligand, ligand receptor (antiligand), enzyme inhibitor (antienzyme), and enzyme substrates, and the enzymatic activity in the assay medium determined. By comparing the observed enzymatic activity with an unknown to the enzymatic activity observed in an assay medium with a known amount of analyte, the amount of analyte can be quantitatively determined.Kits are provided having matched amounts of enzyme-bound-ligand, antienzyme and, when appropriate, antiligand for use in the subject assay.
