摘要:
The invention relates to a method for detecting an infection of a mammal with an acid-resistant microorganism comprising the following steps: (a) provision of an immunochromatographic test with a sample application area for the application of a stool sample of the mammal with an antigen and application of the stool sample, (b) incubation of the stool sample using (i) a first receptor under conditions permitting a complex formation of the antigen from the acid resistant microorganism with the receptor; or (ii) at least two different first receptors under conditions permitting a complex formation of the antigen from the acid-resistant microorganism with the at least two first receptors and wherein the first receptor according to (i) or the first receptors according to (ii) specifically bind(s) an antigen which shows, at least with some mammals, a structure after passage through the intestine that corresponds to the native structure or the structure against which a mammal produces antibodies against after being infected or immunized with the acid-resistant microorganism or an extract or lysate thereof or a protein therefrom or a fragment thereof or a synthetic peptide produces antibodies; and (c) provision of a second receptor immobilized at an analysis region, wherein the second receptor binds an antigen receptor complex according to (b) and (d) transport and detection of the formation of at least one antigen receptor complex according to (b) by accumulation of the antigen receptor complex at the second receptor in the analysis area. The invention further relates to an immunochromatographic test which is particularly suitable and designed to carry out the method of the invention.

摘要:
The present invention concerns a method and apparatus for automatic processing a biological sample on a carrier, perhaps robotically, by applying predetermined amounts of reagents in a predetermined sequence according to a processing protocol, the processing including pre-treatment steps, under the control of an adaptive processing control system using a sample process parameter input that may be independent and an independent process parameter memory that does not interrupt process operation when being used, such that samples may be added or removed without interrupting the processing of other samples. Also included is an image capture function for sample and reagent identification and process monitoring, as well as temperature regulation and environmental control functions.
摘要:
An automated staining apparatus and a method for treating samples arranged on a carrier is disclosed, in which portions of two or more selected reagents from a first station containing the reagents are collected individually by a robot arm handling a probe and dispensed in a mixing station of the apparatus. After mixing the reagents in the mixing station, e.g. by shaking or rotating the mixing cup containing the reagents, the reagent mixture is applied to selected samples by the robot arm and a probe.

摘要:
A tangible computer-readable storage device storing computer-executable program instructions that generate a user interface for displaying workflow information associated with a tissue specimen in a pathology laboratory. The program instructions may be configured to perform a method including displaying a virtual laboratory component representing a physical pathology laboratory having one or more laboratory stations for processing the tissue specimen, wherein the tissue specimen is processed by the one or more laboratory stations according to a workflow, and displaying a specimen indicator that indicates a current specimen state based on a current relationship of the tissue specimen to the workflow. The method may further include enabling a first active component associated with the virtual laboratory component, wherein the first active component is configured to receive a user selection of a laboratory station and generating a supplemental view component of the selected laboratory station in response to the user selection, wherein the supplemental view provides supplemental information on processing by the selected laboratory station of the tissue specimen.
摘要:
There is disclosed a method of pre-treatment and staining, according to a protocol, of a biological sample disposed upon the surface of a carrier, the method comprising the step of recording at least one parameter relating to at least one protocol step in a non-volatile memory located either upon or within the carrier or a device incorporating the carrier. Also disclosed is a device comprising: a non-volatile memory; a surface of the device adapted to carry a biological sample; and communications means electrically coupled to the memory for enabling data transmission to or from an external apparatus. Also disclosed is a method of controlling processing of a biological sample disposed upon a carrier, comprising: providing, upon or within the carrier or an apparatus holding the carrier, a non-volatile memory having information relating to sample processing priority or protocol; reading the information; and scheduling the processing based upon the information.
