bladder tumor antigen Abbreviation: BTA
A protein released into the urine by malignant cells in the bladder, studied as a possible marker of cancer of the urinary bladder. Because of the low prevalence of bladder cancer in the population at large, and the low positive predictive value of the test, the U.S. Preventive Services Task Force (2006) discouraged health care professionals and patients from using this screening test.
