Interpretive Data
Results of this test should not be interpreted as absolute evidence of the presence or absence of bladder cancer. Any disease that would cause endogenous human complement factor H (hCFH) to leak into the bladder can cause a positive test result. Positive results have been associated with renal stones, nephritis, renal cancer (including upper tract TCC), urinary tract infections, cystitis, sexually transmitted diseases and recent trauma to the bladder or urinary tract. This test should not be used as a screening test for individuals without biopsy-confirmed bladder cancer. The result from the BTA stat test should be used only in conjunction with information available from the clinical evaluation of the patient and other diagnostic procedures.
