Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — Urine Testing

Toxic heavy metals and essential nutrient imbalances can silently undermine your health. Discover how at-home elements testing using dried urine and blood spot samples can uncover what standard tests miss.

   Hormones play a pivotal role in the intricate dance of human biology, orchestrating various physiological processes that influence our health and well-being. Understanding the science behind hormone testing is crucial for unravelling the mysteries within our bodies. With 25 years of expertise, ZRT Laboratory stands as a beacon in this field, offering innovative and meaningful hormone and wellness testing. Let’s delve into the complexities of hormone testing and explore the various matrices that reveal the secrets of our hormonal balance. The Symphony of Hormones: Endocrine glands, such as the ovaries, testes, thyroid, pituitary, and pancreas, produce hormones that regulate...

  By Dr. Alison McAllister, ZRT Laboratory This article tackles some frequent questions providers might have regarding the purpose of the testing and who the ideal patient is. TESTING SPECIFICS Why urine testing instead of saliva? Saliva testing is what ZRT was founded on, and we have tested over 1.8 million individuals at this point. We are celebrating 20 years of hormone testing this year! Hurray! We love saliva testing. But, what we don’t love is having you collect every other day for 15 samples. Urine testing has the benefit of a super easy collection – wake up and pee on...

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.
