Hello from JustAnswer. This is Dr. Love.

It is impossible to prove what causes a false positive for an individual on a single test. Performing multiple tests over time, with and without a potential interfering substances may be able to prove that the substance is actually causing a false positive.

For an individual on a single test, the usual approach is to perform a confirmatory test whenever a screening test is positive. If the confirmatory test is negative, then that is proof that the screening test was a false positive, but does not prove what caused the false positive.

Even if someone is taking something that has been shown to cause false positives in others, that does not prove that it has caused a false positive in you, but the confirmatory test does prove that there was a false positive.

Regardless, the next step to prove whether the screening test is a false positive is getting a confirmatory test.
