Description:
The original bladder tumor antigen (BTA) test is a latex agglutination test that detects basement membrane degradation complexes. Two new versions of this test emerged recently (BTA-Stat™ and BTA-Track™), which measure the human complement factor H in urine. BTA-Stat test is a qualitative assay performed as a point-of-care test at the bedside and BTA-Track is a quantitative ELISA test that requires sending the urine sample into a reference laboratory. In a series of studies, the sensitivity of BTA ranged from 32 to 74% while its specificity was 40–96%. The sensitivity and specificity of the original BTA test was comparable to urine cytology. However, BTA-Stat showed slightly higher sensitivity, but much lower specificity, than urine cytology.
