Hands-on analytical chemistry (specifically gas chromatography and mass spectrometry) is a direct part of my profession, and that's all I care to disclose publicly. But, that doesn't matter.
Brushing your
ad hominem attacks aside, you should be interested to learn that false positives are a reality in this field. Development of any analytical test method involves isolating interferences. This had not been done thoroughly at least by the time of the testing (as denoted by the researchers), and dealing with proteins and a urine sample that is
5-6 years old raises additional concerns.
If that doesn't register, maybe this will:
... which raises concerns about the possibility of false positives from testing used at that time:

And finally, a study conducted by Mujika on the efficacy of the test at that time concluded:
"
Conditions of storage and transport of the urine can also seriously affect the validity and reliability of the test."

If you have any further questions, you can ask them because I have better things to do with my time.
