What does the Phenylethylamine test measure?

Why is Phenylethylamine measured?

Functional practitioners interpret urinary phenylethylamine as a marker of mood, motivation, and reward. Low levels are hypothesised to correlate with depression and attention deficits, though the evidence base is limited and the relationship to central nervous system monoaminergic activity is indirect.
