Can the numbing eye solution that is given in an opthalmologic eye exam cause a "positive" in a urinalysis?

I have not taken any drugs other than OTC pain medications for the last 5 years (this includes prescription or otherwise)...yet a recent 5-panel drug screen for a new job showed up "positive" for drug use.

I think they usually use tetracaine (not cocaine) in eye drops. (Cocaine is used in nasal surgery, though.) Sometimes mistakes are made in the lab. Request another test.
