The Cxbladder Hematuria Clinical Utility Study

Purpose

To evaluate the clinical utility associated with the integration of Cxbladder into the evaluation of subjects presenting with hematuria for evaluation of urothelial carcinoma (UC) without compromising detection of UC.

Arm Groups

Arm	Description	Intervention
No Intervention Control	Subjects on the control arm will be on standard of care. Trial nomogram clinical risk factor categorization for control arm subjects will not be provided to the physician (but appropriate information will be collected on the CRF to enable sub-group analysis) No Cxbladder test results will be provided for control arm subjects. Note that Cxbladder test results will be available for eventual analysis for these subjects.
Active Comparator Test, subjects categorised as "low risk" or "Not low risk"	A clinical risk factor nomogram risk classification will be used in this study. The nomogram categorizes subjects as either "low risk" or "not low risk" categories. "Low risk" subjects satisfy all conditions and "not low risk" satisfies at least one of the conditions.The Cxbladder Triage test result will be provided to physicians for all "low risk" subjects on the test arm. If a "low risk" subject has a Cxbladder Triage negative test result then the indication is to rule out the subject without further assessment. The decision to rule-out or further evaluate is solely that of the physician and subject. If the "low risk" subjects are not Cxbladder Triage negative then a Cxbladder Detect test result will also be provided. The indication is further evaluation as per standard of care. Subjects categorised as "not low risk" will be evaluated as per standard of care. Note that Cxbladder test results will be available for eventual analysis for these subjects.
