An analytical test element for determining an analyte in a body fluid comprises a detection area in which the analyte is detected and an application site at which the body fluid can be applied to the test element. The application site is spaced apart from the detection area, wherein at least some of the body fluid applied to the application site moves from the application site to the detection area. The test element also comprises a contamination area which at least partially adjoins the application site, wherein an adhesive substance is applied to at least part of the contamination area of the test element. The adhesive substance adheres to the contamination area of the test element and is able to interact with an excess amount of applied body fluid such that at least some of the body fluid adheres to the test element and thereby an excess amount of body fluid remains in the contamination area. An additional embodiment provides for test elements which, after use, can be stored in a storage container. Another embodiment provides for the production of the test elements.

A method of a visual test authoring and automation solution framework for an enterprise comprising supporting the creation of a test case for a visual application. First, the framework allows a user to assign a user-defined name to a test element, and select an action to be performed on the test element from a menu of actions. Second, the framework stores a mapping of the user-defined name assigned to the test element to a coded name in a corresponding language of an automated testing tool. Lastly, the system uses the mapping and the action selected to create the test case in the corresponding language of the automated testing tool.

The invention includes a method for testing a spreadsheet cell. Du-associations are collected for the spreadsheet cell. The cell's execution trace is tracked. After the user validates the cell, the du-associations that participated in the execution trace are marked as executed. Du-associations for other cells that are affected by the testing a spreadsheet cell are similarly marking as exercised. If the user changes a cell's contents, the collected du-associations for the cell are discarded and the steps of collecting test elements, tracking execution traces, and marking are repeated. Cells that depend on the changed cell also repeat these steps. After the user marks a cell as validated, a validation symbol is shown on the cell. If the cell's validation status is later brought into question, the validation symbol can change or be removed entirely. The invention also includes a method for providing a user with feedback of the testedness of the spreadsheet cells. The du-associations for each spreadsheet cell are maintained, and the subset of du-associations that have been exercised is identified. Using the numbers of tested and untested du-associations, a testedness measure is calculated for the cell, which is provided to the user.

The invention relates to embodiments of an analysis system and to a method for analyzing a sample on an analytical test element, with the analysis system comprising a test element receptacle for receiving and positioning a test element in an analysis position. In an exemplary embodiment, the test element receptacle contains a guide part and a lock part, the guide part having means for guiding a test element into and out of the analysis position, the lock part comprising a frame and a bolt element, which frame and bolt element are connected to one another by a hinge. The bolt element can be pivoted about the hinge between a first position and a second position with respect to the frame. The bolt element comprises a latching lug for engaging in a recess in test element when the bolt element is in the first position and when the test element is positioned in the analysis position.

The present invention is directed to devices and methods for determining the presence of analyte in a fluid sample. The devices utilize a sample collection well, an expression plate for expressing sample into the sample collection well, a plunger that drives a lance, and a test compartment containing test elements. The devices also preserve an aliquot of fluid sample in a reservoir for later confirmation testing. When the plunger is lowered into the sample collection well, a lance on the device punctures a frangible material that covers a sample outlet. When the sample outlet is thus opened, fluid sample flows from the sample collection cup to the test compartment. In one embodiment the plunger is lowered as a cap is applied to the device. The devices are useful for detecting the presence of analyte in a wide variety of fluid samples, such as saliva, oral fluids, and more. The invention also provides methods of using the devices, and kits containing the devices.
