Trial Outcomes & Findings for Evaluation of the Accuracy and Usability of the ACR | U.S. Urine Analysis Test System in the Lay User Hands (NCT NCT04626271)

NCT ID: NCT04626271

Last Updated: 2023-05-09

Results Overview

The primary objective of the study is to evaluate the % exact match (percent agreement) and the % ±1 block match (percent agreement) of ACR \| U.S. Urine Analysis Test System (tested by the lay user) compared to the URiSCAN Optima Urine Analyzer (the comparator device, tested by a healthcare professional user), for all reported values (blocks). Different concentrations reported by the ACR \| U.S. Urine Analysis Test System were compared with results from the comparator device.

PRIMARY outcome

Timeframe: 2 months

Population: Each study participant was asked to perform the test twice: first, by using their preferred platform device (iOS or Android), in which usability and accuracy were evaluated; and secondly by using the other platform device, which was assessed for accuracy only. In addition, 23 spiked samples were used in order to achieve sufficient sample sizes for all analyte blocks, each sample on both platforms as well.

The primary objective of the study is to evaluate the % exact match (percent agreement) and the % ±1 block match (percent agreement) of ACR \| U.S. Urine Analysis Test System (tested by the lay user) compared to the URiSCAN Optima Urine Analyzer (the comparator device, tested by a healthcare professional user), for all reported values (blocks). Different concentrations reported by the ACR \| U.S. Urine Analysis Test System were compared with results from the comparator device.

SECONDARY outcome

Timeframe: 2 months

The usability of the ACR \| U.S. Urine Analysis Test System was determined by evaluating the percentage of study subjects able to perform all required steps and successfully complete the test given only the instructions and training materials provided. In addition, each subject was asked to complete a post test questionnaire to assess the device ease of use by rating the various test steps on a scale of 1 to 5, with 5 being the easiest ("very easy") and 1 the hardest ("very hard"). This questionnaire also included understanding questions in a multiple-choice, quiz-like format, to assess the participants' understanding of essential information and key test procedures in the study.
