Dried urine testing is rapidly becoming the preferred method for neurotransmitter and hormone assessment — but collection timing is everything. In this clinical overview, Dr. Kate Placzek of ZRT Laboratory explains why a single morning urine sample cannot substitute for a 4-time-point collection, how neurotransmitters like epinephrine and norepinephrine follow distinct diurnal rhythms, and why interchanging the first and second morning voids can produce grossly inaccurate results.

Discover how certain foods rich in serotonin and dopamine — including bananas, walnuts, pineapples, avocados, and nut butters — can interfere with urinary neurotransmitter testing and lead to false-positive results. Learn why proper test preparation matters, how neurotransmitter urine analysis is interpreted, and how combined neurotransmitter and cortisol testing can provide deeper insight into mood, stress, brain chemistry, and hormonal balance.
