title: NMP22 BladderChek Test: point-of-care technology with life- and money-saving potential.
abstract: A new, relatively obscure tumor marker assay, the NMP22 BladderChek Test (Matritech, Inc.), represents a paradigm shift in the diagnosis and management of urinary bladder cancer (transitional cell carcinoma). Specifically, BladderChek should be employed every time a cystoscopy is performed, with corresponding changes in the diagnostic protocol and the guidelines of the American Urological Association for the diagnosis and management of bladder cancer. Currently, cystoscopy is the reference standard and NMP22 BladderChek Test in combination with cystoscopy improves the performance of cystoscopy. At every stage of disease, BladderChek provides a higher sensitivity for the detection of bladder cancer than cytology, which now represents the adjunctive standard of care. Moreover, BladderChek is four-times more sensitive than cytology and is available at half the cost. Early detection of bladder cancer improves prognosis, quality of life and survival. BladderChek may be analogous to the prostate-specific antigen test and eventually expand beyond the urologic setting into the primary care setting for the testing of high-risk patients characterized by smoking history, occupational exposures or age.
