The purpose of this proposal is clinical validation of an electrochemical biochip for rapid pathogen identification and antibiotic susceptibility determination.

Study summary:

Point-of-care identification of pathogens and determination of antibiotic susceptibility will significantly improve the clinical management of urinary tract infection. We have previously developed a biochip based on microfabrication technology capable of rapid detection of pathogens. The specific objectives of the current proposal are: 1) Determination of microbial constituents in spinal cord injury (SCI) patients and development of additional species-specific probes against these pathogens; 2) Development of a rapid antibiotic susceptibility and molecular pyuria assay using the electrochemical biochip; and 3) Clinical validation of the biochip as a diagnostic test for urinary tract infection. Within a single protocol, two non-interventional studies were conducted at different time points to achieve the aforementioned objectives. Sensitivity and specificity of the electrochemical biosensor based assay was demonstrated in each study.


Inclusion Criteria: - Patients suspected or at risk for complicated urinary tract infections Exclusion Criteria: - Gross contamination of urine samples at the time of collection
