A detection method for enhancing detection signal intensity is provided. The detection method includes the following steps. Firstly, a detection device is provided. The detection device includes a channel, an inlet port and an air chamber. The air chamber includes an elastic layer. A bonding material is immobilized in the channel and served as a reaction area. Then, a sample containing a detection material is loaded into the inlet port. As the elastic layer is moved upwardly and downwardly, the sample is moved toward the air chamber and the inlet port in a reciprocating manner. Consequently, the possibility of combining the detection material of the sample with the bonding material in the reaction area is increased. Afterwards, an optical signal from the reaction area is measured.

Lateral flow devices and methods of use for a molecular diagnostic assay are provided. The method is suitable for detection or monitoring of targets, including biological, chemical, and material targets that exist in very low concentrations in biological samples. The methods and devices of the present application are amenable to power source-free point of care testing.

Methods are provided for the automated detection of assay-positive assay areas in a microfluidic device. When assays are performed in a microfluidic device, the configuration of the microfluidic circuit and its constituent circuit elements can determine where the reagents/analytes used in the assay can be located within the microfluidic circuit. Methods are provided for automatic identification of the size and shape of the assay areas based on a number of parameters which may include type of assay involved, shape and dimensions of microfluidic circuit elements, velocity and physical characteristics of the fluidic medium within the microfluidic circuit, physical/chemical properties of the analytes/reagents, and/or the number of cells being assayed.

In various implementations, a noninvasive, food sensitivity test may be utilized to identify one or more food sensitivities. A fecal sample may be obtained. The food sensitivity test may be performed on the obtained fecal sample. One or more food sensitivities may be identified based on the food sensitivity test.

Methods and systems for colorimetrically analyzing a liquid medium by analyzing chemical test strip images are provided. The liquid medium can be industrial water in an industrial water system. Image analyzing software carries out the analysis. The results of the analysis can be used to diagnosing a chemical treatment regimen of the industrial water system. A chemical test strip holder can be used to enhance reliability and repeatability of the imaging process and/or subsequent analysis.

The invention relates to methods for detecting target DNA sequences, particularly for detecting Leishmania infection, comprising a recombinase-polymerase isothermal amplification and detection by electrochemistry. The invention also relates to kits and oligonucleotides for performing said methods.

A test pad comprising multiple urine attribute patches and urine detection patches in a BAYER pattern is described. The test pad is suitable for automated urine analysis of multiple animals in a cage. Generalized detection patches may be arranged adjacent to and surrounding each individual test patch for a specific urine attribute. First, fresh urine is detected in a detection patch with a camera; a timer is started; then adjacent urine attribute patches are read. Once a test patch has been used once it is disregarded for future analysis.

The invention discloses a microfluidic blood type detection chip. The chip comprises a chip body, and the chip body comprises: a forward typing blood type identification area, which is provided with a first sample injection chamber, a quantitative mixing chamber, a forward typing reaction chamber, and a vent hole; a reverse typing blood type identification area, which is provided with a second sample injection chamber, a quantitative separation chamber, a reverse typing reaction chamber, and a vent hole; a sample is injected into the first sample injection chamber, from which the sample and preset diluent flow into the quantitative mixing chamber through a microfluidic channel; after the sample and the diluent are mixed in the quantitative mixing chamber, they enter the forward typing reaction chamber to react with a reaction reagent for detection; a sample is injected into the second sample injection chamber, and enters the quantitative separation chamber through a microfluidic channel, the sample is separated in the quantitative separation chamber, and separated plasma enters the reverse typing reaction chamber and reacts with a reaction reagent for detection. The present invention can realize the simultaneous forward and reverse typing blood type identification, so that the results of blood type identification are more accurate.

A multi-fluid test strip may include a first zone to test a first fluid, a second zone to test a second fluid, and a third zone intermediate the first zone and the second zone. The third zone may prevent cross-contamination of the first fluid with the second zone and prevent cross-contamination of the second fluid with the first zone. The multi-fluid test strip may also include a first grip zone and a second grip zone. The first zone may be intermediate the first grip zone and the third zone and the second zone may be intermediate the second grip zone and the third zone. The first grip and second grip zones may be dimensioned to permit gripping of the first and second grip zones without touching the first or second zones.
