Systems, methods, and test kits for monitoring and detecting variation in an analyte level in a fluid sample from an individual variation using a uniquely determined analyte threshold value. In one implementation, luteinizing hormone is the monitored analyte and is compared with the determined threshold value to predict the onset of ovulation for the individual.

Systems, methods, and test kits for analyte variation detection

An improved qualitative or semi-quantitative diagnostic test for measuring low levels of any analyte, such as hCG, in a biological sample, such as urine. The test comprises a test device containing reagents for the detection of the monitored analyte and an electronic reader that measures color development at a detection area of the device. The color development is converted to an electronic or digital signal. Improvements were made to the electronic reader to optimize the coverage of the detection area on the test strip. This improves the detection sensitivity and consistency of the test result while maintaining its reliability and accuracy.

Devices and methods for electronic analyte assaying

Systems, methods, and test kits for detecting and quantifying an analyte level in a biological fluid sample using impedance measurements, are disclosed. The fluid sample is applied to a lateral flow strip, and impedance of the strip is measured as the assay dries. Analysis of the drying-dependent impedance measurements indicates the presence and quantity of the analyte in the fluid sample.

Systems, devices and methods for a hydroscopic based lateral flow assay

Test kits for assessing male fertility include a sample holder defining an object plane, a lens, and a two dimensional light sensor defining an image plane arranged along a common linear axis. The distance between the object plane and the image plane may be no more than 50 mm, and may be no more than 30 mm. A lens aperture may have an area of 1-10 mm. The test kit may have a housing with a maximum linear dimension of no more than 100 mm. Processing circuitry may be provided that is configured to produce a sperm count and/or sperm motility measurements by processing image data from the two-dimensional light sensor.

Sperm motility test device and method

The invention provides an apparatus and methods for the electrochemical detection and/or quantitation of an analyte in a sample, wherein the device comprises a substrate and a detector, wherein the substrate comprises a labeled binding agent, wherein the label is an enteric material particle that encapsulates a ferrocene methanol redox species.

Method and apparatus for electrochemical detection

The invention comprises a device for detecting an analyte in a liquid sample deposited on a first portion of the device for transport to a second portion of the device that is in fluid contact with the first portion. In specific embodiments, the device is a pregnancy test device, which detects human chorionic gonadotropin (hCG) as an indicator of pregnancy. Devices with improved clinical sensitivity are provided which are capable of detecting all clinically relevant hCG isoforms.

Diagnostic detection device

The present invention is related to a diagnostic test kit that assesses ovarian reserve by measuring Follicle Stimulating Hormone (FSH) in a liquid sample. The sample can be deposited on a first portion of the device for transport to a second portion of the device. The device can include a release medium formed of a first material and including a detectable label thereon and a capture medium, including a test site, in fluid communication with the release medium and formed of a second, different material.
