Neurotransmitters are chemical messengers that transmit signals between nerve cells in the nervous system. A balanced level of these neurotransmitters is essential for overall health. When imbalanced, they can cause neurological or psychological issues, such as anxiety, depression, chronic fatigue, or insomnia.

ZRT offers a unique approach to neurotransmitter testing, analyzing 14 key neurotransmitters and metabolites to provide a comprehensive view of your neurochemistry. Unlike other labs, ZRT combines parent neurotransmitter levels with their downstream metabolites, ensuring accurate results and more effective treatment plans. This comprehensive testing, available exclusively through ZRT, helps identify systemic patterns that may be contributing to your health issues.

Neurotransmitter imbalances are often linked to common conditions like anxiety, depression, ADHD, and PMS. ZRT’s testing also examines the influence of hormones, heavy metals, and nutritional elements, offering a more complete and precise understanding of your health.

For the most accurate and convenient testing, ZRT's dried urine method allows for discreet, at-home collection—no need for all-day urine collection. The dried strips are easy to mail back, providing a hassle-free way to assess your neurotransmitter levels.

Heavy metal exposure can have detrimental effects on a child's development and overall health. However, with the advent of Heavy Metals Testing Kits, parents now have a convenient and accurate method to assess heavy metal levels in their children's bodies. These testing kits utilize dried blood spots and dried urine spots, offering a comprehensive solution to evaluate exposure to a range of toxic heavy metals. In this article, we will explore the benefits of heavy metals testing for children, focusing on the 14 essential elements tested through the Heavy Metals Testing (Comprehensive Toxic and Essential Elements) Profile. Detection of Toxic...

By Theodore Zava, ZRT Laboratory It seems like there is an endless loop of stories these days about new viruses and the spread of disease. There is no doubt that as the human population increases and the space between us decreases, we will only experience more of these events in the future. While the world waits on new vaccines, one solution to slowing or preventing the spread of viruses may be something as simple as adequate selenium nutrition. How Selenium Protects Against Viral Infections and Mutations Adequate selenium nutrition should be considered as a defense against viral infectious diseases. Selenium...

By Dr Kate Placzek, ZRT Laboratory Influenced by our environment, we are constantly being exposed to elements, whether nutritional or toxic. They are a big contribution to the yin yang dualism of health and disease.  With heavy metals, contamination is so extensive nowadays that it is no longer a question of whether exposure took place, but rather what the level of exposure was or continues to be. Toxicity from low levels of exposure can lead to a wide array of neurological disturbances and can be much more insidious in presentation than acute toxicity, which is, in contrast, rather obvious in...

By Theodore Zava, ZRT Laboratory. Selenium is a trace essential element that is incorporated into selenoproteins. There are at least 25 known selenoproteins in the human body, their primary roles being antioxidant enzymes such as glutathione peroxidase and thyroid deiodinases that convert thyroxine (T4) to active thyroid hormone (T3). Deficiencies in selenium can be detrimental to health, while selenium excess can be just as dangerous. Brazil nuts are commonly used as a form of selenium supplementation, but it isn’t commonly known that the level of selenium in Brazil nuts is highly variable.   Why Are Brazil Nuts High in Selenium?...
