Podcast - "Ask the Expert" - We Tried NMP22 Five Years Ago when it First Came Out and after Receiving False Negatives, We Elected to not Continue its Use. Do you have Confidence in the Sensitivity of the Test?We tried NMP22 five years ago when it first came out and after receiving false negatives we elected to not continue its use. Do you have confidence in the sensitivity of the test?
Answer: Dr. Barry Stein
Yes I really do. I think we have a lot of experience now and publications telling us exactly what the false positive and negatives are; for example, someone with gross hematuria or infections or stones where we are likely to see the “false positives.”
I think we have a good idea that this is very sensitive and specific - far more so than cytology. If anybody trusts cytology you have all the more reason to believe this is much more trustworthy as a test and much less expensive.
