BTA test

Bladder tumour antigen test. A qualitative, point-of-care test that identifies a human complement factor H-related protein, which is produced by several human bladder cell lines but not by non-malignant epithelial cell lines. It has a claimed sensitivity comparable to that of cytology for high-grade tumours and claimed to be better than cytology for low-grade tumours.
