Problems solved by technology

However, this improvement is limited by the increased susceptibility of the device to detect background amounts of biomarker analytes that are naturally present in the sample, e.g. leading to a larger number of false positive results
Often, the background production of biomarker analytes thus constitutes "physiological noise" and creates limitations in utility in the improvement of the sensitivity of certain diagnostic devices

Embodiment Construction

[0100] figure 1 A device for identifying a target condition in a body, in particular a test device 1 , according to a first embodiment of the present disclosure is shown in . The testing device 1 is configured to test a woman for pregnancy after receiving a urine sample from the woman.

[0101] The test device 1 comprises an elongate lateral flow test strip 10 and a housing 11 . The test strip 10 is partly accommodated in the housing 11, the sampling end 100 of the test strip 10 protruding from an opening 111 in an end surface 112 of the housing 11, enabling a urine sample to be directly received thereon. The sampling end 100 of the test strip 10 is covered by a cap 12 . The testing device 1 also includes an LCD display 36 visible through the opening 13 in the top surface 113 of the housing 11 for displaying test results.

[0102] The test device 1 is a handheld device configured to identify pregnancy by identifying the amount (level) of both hCG and LH hormones in a urine...

Abstract

An apparatus for identifying at least a first target condition in a human or animal body is disclosed. The device includes one or more testing sections for identifying: a first analyte in a biological sample from the body, the first analyte providing a biomarker of a first condition of interest; and a second analysis in the biological sample analyte, the second analyte is different from the first analyte. The device is configured to identify a first target condition in the body based on identification of both the first analyte and the second analyte. In one embodiment, the first condition of interest is pregnancy, the first analyte is human chorionic gonadotropin (HCG), and the second analyte is luteinizing hormone (LH).

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Australian Provisional Patent Application No2012904238 filed 27 September 2012, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to devices and methods for identifying conditions such as pregnancy in the human or animal body. Background technique [0004] Various types of diagnostic devices exist for identifying a medical condition of interest in a human or animal. Increasingly, these devices are designed for home use. These devices analyze biological samples from humans or animals, such as urine samples, blood samples, etc., and identify analytes in the samples that provide biomarkers of a condition of interest. [0005] One of the most widely used and recognized diagnostic devices is the home pregnancy test, which usually employs lateral flow technology and uses human chorionic gonadotropin (hCG) as a bioma...
