Evaluation of the Accuracy and Usability of the ACR | U.S. Urine Analysis Test System in the Lay User Hands
Eligible subjects meeting the pathological profile will be recruited at the designated site by the study personnel. Following subject consent, the subjects will be evaluated for eligibility based on their health condition and history.
The ACR | U.S. kit, in its original packaging, along with the ACR | U.S. smartphone application will be provided to the subject in a simulated home- use environment. All subjects will be provided with a list of tasks to complete, including providing a urine sample and operating the ACR | U.S. device on 2 mobile phones. After completing the test, the lay user will complete a post-test questionnaire. The study observer will also complete a questionnaire to collect information regarding the lay users' use of the ACR | U.S.
The device use will be compared with identified risks to determine if the percentage of failures is acceptable. Additionally, measurable usability criteria for specific, critical steps will be evaluated.
Following the usability test performed by the lay user, the subjects' urine samples will be tested by the study staff using the comparator device. These results will be considered as the "true value".
