The indentation has a first receiving area to receive an elongated test strip as well as a second receiving area to receive an end section of a fluid line. The second receiving area is in fluidic communication with the first receiving area. A maximum width of the second receiving area at bottom height is greater than a maximum width of the first receiving area at bottom height.

A test device is configured for diagnostic testing and includes an optical readable medium, in turn including a pattern of spots of material arranged on a surface of the device. Several patterns may be provided. The patterns accordingly formed may be human and/or machine readable. They may notably encode security information, e.g., indicating whether the device has already been used. The spots may notably be inkjet spotted. In addition, a method is provided for decoding information encoded in a pattern of such a test device. In embodiments, liquid is introduced in the device, which comprises additional spots having a substantially different solubility than spots forming the actual pattern. Thus, the additional spots get solubilized in and flushed by the liquid as the latter wets them, and an initially hidden pattern may be read, which is formed of the remaining spots (not solubilized). Encoding methods are also provided.

The detection module captures a color signal of the detection test papers passing through the second position. The processing unit generates a water quality signal according to the color signal.

A test strip code reader is provided. The test strip code reader includes a test strip carrier for accommodating a test strip, a first conductive element for decoding a code of the test strip, a second conductive element configured to be in a contact state or a separation state with the first conductive element, and an activation element having a body and a plurality of protrusions, wherein the body is used to prevent the first conductive element from being contaminated, and according to whether the plurality of protrusions are actuated by the test strip, the contact state or the separation state between the first conductive element and the second conductive element is determined to decode the code of the test strip.

The testing chip includes a first layer on one surface side and a second layer on another surface side, in which either the first layer or the second layer has a liquid-receiving section A, the first layer has at least a detection-confirming section B, the second layer has at least a liquid-distributing section D adjacent to the detection-confirming section B and a liquid flow path E connected to the liquid-distributing section D, the testing chip is configured such that when the test liquid is dropped onto the liquid-receiving section A, the test liquid distributes in a predetermined order by capillary action to reach the detection-confirming section B, and among surfaces of the first layer and surfaces of the second layer, at least surfaces of material M other than the liquid-receiving section A are sealed with a film.

A diabetes test system for measuring blood glucose levels is provided, which includes a glucose meter, at least one diabetic test strip, and a container or pouch for storing the diabetes test strips and protecting them during transport. Methods of packaging diabetes test strips are also provided. The glucose meter includes software for detecting the validity of the at least one diabetic test strip, and a communication device that transmits data relating to the blood glucose level of the user to an external device. A secure packaging system for diabetes test strips which eliminates gray market sales of such test strips is also provided.

Contamination detection systems, kits, and techniques are described for testing surfaces for the presence of hazardous contaminants, while minimizing user exposure to these contaminants. Even trace amounts of contaminants can be detected. A collection kit provides a swab that is simple to use, easy to hold and grip, allows the user to swab large areas of a surface, and keeps the user's hands away from the surface being tested. The kit also provides open and closed fluid transfer mechanism to transfer the collected fluid to a detection device while minimizing user exposure to hazardous contaminants in the collected fluid. Contamination detection kits can rapidly collect and detect hazardous drugs, including trace amounts of antineoplastic agents, in healthcare settings at the site of contamination.

Reading method of a lateral flow test using a cassette and a reader. The cassette has a window through which there is observed a test strip, the test strip having a reactive zone with a test line and a control line. The reader has a light emitter for illuminating the cassette and a sensor for receiving the light reflected by the cassette. The method incudes manually moving the cassette and obtaining a signal of the light reflected by the cassette, normalizing the signal in a range defined between a lower value and a higher value, and identifying peaks in the signal corresponding with the test and control lines. The lower value and the higher value are established between the light reflected by the cassette outside the window and the light reflected by the test strip outside the reactive zone.
