A test device is provided that can comprise: a housing accommodating a chromatography support, wherein the housing comprises: a supporting part that supports a container accommodating a liquid used for chromatography. A method is provided for performing chromatography using the test device.

A test strip for sampling a bodily fluid may include multiple layers of a substrate material, an adhesive between at least some of the multiple layers, and a microfluidic channel formed between at least some of the multiple layers. The test strip may further include multiple electrodes on one of the multiple layers, positioned and partially exposed within the microfluidic channel, an additional material positioned at or near an entrance to the microfluidic channel, to selectively limit the flow of at least one of bubbles or debris into the microfluidic channel, and at least one exit port in at least one of the multiple layers to allow for release of pressure from the test strip. In some embodiments, the test strip is a saliva analysis test strip. In some embodiments, the test strip includes multiple exit ports to prevent blockage of sample flow.

The invention relates to a strip holder consisting of a housing with a front side and a back side, the housing comprising at least one strip receiving channel, at least one fluid receiving channel, at least one fluid reservoir, and optionally at least one ventilation channel. The invention also relates to a use of the strip holder, a method as well as to a kit comprising the strip holder.

A method is taught for the accurate determination of the premature rupture of membranes (PROM), defined as spontaneous rupture of membranes before the onset of uterine contractions. More specifically, a lateral flow assay strip tests for at least two antigens to greatly limit or eliminate the possibility of false negatives. A built-in timer in the cassette holding the lateral flow assay further increases the accuracy of the test. A collection buffer vial with self-contained shipping and dropper caps and built-in stand is also taught.

Examples herein provide a device. The device includes a sample delivery component, which includes: a reagent chamber to contain at least one reagent; a sample chamber to contain a fluid sample; and a delivery channel extending from the reagent chamber and in fluid communication with the sample chamber and an output port, wherein the delivery channel is conducive mixing the at least one reagent and the fluid sample to form a mixture before the mixture reaches the output port and be discharged therefrom. The device includes a testing cassette detachable from the delivery component, which includes: an input port in fluid communication with a microfluidic reservoir, the input port to receive the discharged fluid sample from the output port; and a micro-fabricated integrated sensor in a microfluidic channel extending from the microfluidic reservoir.

A portable point of care device (1) for use in testing a biological sample, the device comprising: a sample collection member (4), a test cartridge (2), and a reader (220).

A sample of blood is placed on a bilirubin test strip and plasma separated from the red blood cells. The bilirubin test strip is located on a test card along with a set of calibration images, the colors of the calibration images being associated with known plasma bilirubin levels. A photograph is taken of the test card. The bilirubin level of the blood sample is determined by, within the photograph, interpolating the color of the plasma and the colors of the closest colored calibration images.

A fully integrated miniaturized optical biosensor and methods of making the same are disclosed. The biosensor may include a fluid transport system and an optical system.

Aspects of the invention provide a biological sample collection pad (e.g., for the collection of fecal, liquid or tissue samples). Method of using such pads and analyzing collected samples are also provided.

Disclosed is a device including a substrate having a plurality of detection areas to receive at least a portion of a sample having an analyte or suspected of having an analyte and at least one reference marker adjacent to at least one of the detection areas, wherein each of the detection areas detects a specific analyte and the at least one reference marker defines a scale mark, a shape mark, a color mark, or a combination thereof. Also disclosed is an imaging system and method for using the device and imaging system.
