HORMONE BALANCE: The Key to Health


Most hormones are produced by a group of glands known collectively as the endocrine system. Even though these glands are located in various parts of the body, they are considered one system because of their similar functions and relationship to each other.

Hormones are secreted into the bloodstream by these glands. From there, they travel to all parts of the body playing the role of chemical messengers turning specific target tissues on or off. Because they can’t be stored in the cells, hormones do their work as they pass through and then they’re gone. As a result, hormones must be made and released at the precise time they’re needed. To keep things functioning at their best, the body must constantly fine-tune hormone release to keep levels within proper limits.

Because of the complexity of these interactions, a hormonal imbalance rarely stems from only one type of hormone. More often, the problem involves a series of hormones that are out of balance. In addition, a disruption in the balance of hormones produced by one gland or set of glands can cause other glands or systems to dysfunction. Before you know it, you’re feeling miserable on multiple fronts.

How to Achieve Hormone Balance
To restore the vital balance of hormones, we first need a detailed, accurate measurement of hormone levels. Not just numbers, but an assessment that offers real meaning. ZRT’s reports are the most meaningful because they combine test levels with self-reported symptoms that are then correlated into a set of individualized comments – all giving unparalleled insight into conditions.


Why do we test hormones in saliva? Steroid hormones in the bloodstream are 95-99% bound to carrier proteins, and in this form are unavailable to target tissues. Saliva testing measures the amount of hormone available to target tissues – the bioavailable amount. For this reason, saliva testing better relates to specific symptoms of excess or deficiency, and is a good option for monitoring hormone therapy.


Why measure in blood spot? Blood spot is ideal for measuring hormones and other analytes such as insulin, blood lipids, Vitamin D, thyroid hormones, and elements like lead and magnesium. It offers distinct advantages over serum because it eliminates the need for a blood draw – saving time and money. ZRT developed the science for accurately measuring hormones in dried blood spot. 


Urine testing is the best way to measure adrenal and sex steroid hormone by-products and their metabolic pathways, providing a gauge for understanding the body’s hormone metabolism. Urine testing is also the preferred method for testing elements like iodine and heavy metals like arsenic and cadmium. Additionally, it’s the most common method for testing neurotransmitters.

Intuitive Graphics

Intuitive graphics allows for quick scanning of a column of results to determine whether levels are high, low or ok.

No need to stop hormone supplementation to use ZRT’s testing because ranges are adjusted for age, menstrual status and supplementation types – which is the ideal method for tracking the effectiveness of hormone treatments.
Detailed Graphs
Graphs act as a visual aid for interpreting results and facilitating discussions. For hormones like cortisol and melatonin that are measured multiple times per day, results are plotted according to the actual time of day the sample was collected.
Symptom Tracking
Individuals indicate how they are affected by 68 common hormone-related symptoms. The color-coded results give added insight into which symptoms are most troubling.
Advanced Symptom Interpretation
Symptoms are summarized into 8 hormone imbalance conditions and scored with red, yellow or green bars to indicate severity. 
Clinically Informed Comments
Individualized comments written by ZRT’s clinicians and scientists address how results relate to your symptoms, resulting in the best and most targeted treatment plan.
