AI Technical Summary

Technical Problem

Manual inspection of urine samples using colorimetric reagent pads is error-prone, subjective, and time-consuming, necessitating an automated solution for accurate and efficient analysis of analytes in urine samples.

Method used

An optical inspection apparatus with a processor that analyzes pixels within images of urine samples to determine the location of indicators and reading areas, and subsequently assesses the presence or absence of predetermined analytes by illuminating and capturing images of liquid sample carriers, such as reagent strips or cassettes, using a light source and sensor.

Benefits of technology

The apparatus provides accurate, objective, and efficient analysis of urine samples, reducing human error and time consumption in determining the presence or absence of analytes, thereby enhancing the reliability of urine analysis.

Abstract

Methods and systems for automatically selecting a region of interest in an image captured by an optical inspection apparatus are herein disclosed. One method comprises analyzing pixels within an image of a liquid sample carrier to determine a location of an indicator within the image, determining a reading area position of a reading area of the liquid sample carrier within the image based on the location of the indicator determined by analyzing pixels within the image, and analyzing pixels within the image depicting the reading area to determine a presence and / or absence of a predetermined analyte in a liquid sample disposed on the liquid sample carrier. The liquid sample carrier may be a reagent strip or a reagent cassette. The indicator may be a fiducial, a symbol, a colored region, or a material configured to appear different when exposed to a particular wavelength of the electromagnetic spectrum.
