You can't fail on color. Any thing suspicious must be confirmed by lab testing and results. Validity testing usually includes specific gravity, pH, sometimes creatinine clearance, and tests for additives. Having a yellow color is not one of them. Your urine can be clear as bottled water and pass all validity testing or it can be day glow yellow and fail validity testing. Don't start adding food coloring to your urine. That is more harm than good.
FakeBoobsRule Reviewed by FakeBoobsRule on . New Job/Interview I'm a student applying for an internship. At the bottom of the extremely long application, there's a note that says that if an offer of employment is made to me, it is conditioned on a urinalysis for both legal and illegal drugs. My interview is on Tuesday, and at the moment, I'm the only applicant for the position. They've expressed their excitement at "getting me started as soon as possible", even though I have yet to even interview. I've made a very good impression thus far. After Rating: 5
