This simple, non-invasive test allows you to understand how your cortisol levels are functioning throughout the day.
Using four saliva samples collected at specific times, this assessment creates a diurnal cortisol curve, showing how your stress hormones rise and fall from morning to night. This gives a much clearer picture than a single blood draw and helps identify patterns of imbalance within the adrenal system.
Balanced adrenal function supports steady energy, stable mood, restful sleep, and overall resilience. When cortisol is out of rhythm, it can impact everything from blood sugar and inflammation to focus, stamina, and hormone balance.
Saliva testing is considered a reliable and convenient way to measure cortisol, and also allows for DHEA evaluation, offering deeper insight into your body’s stress response.
Once your results are in, you can schedule a Functional Lab Review where we’ll walk through your results together and create a personalized protocol to help restore balance.
This is where we move from guessing to understanding.

ZRT has determined that while parent neurotransmitters are helpful in assessing precursor availability, interpreting results based on those levels alone can result in undertreatment, treatment of the wrong part of the system, or overtreatment with direct precursors. It’s only by looking at the parent neurotransmitters with downstream metabolites that you can tell whether there is a systemic pattern.
Given the importance of these levels to correct interpretation of neurotransmitter results and subsequent treatment plans, ZRT Laboratory includes a range of 14 neurotransmitters and metabolites in its testing. This essential collection of tests is available only from ZRT – and not from any other lab.

Get a clear and accurate picture of your Vitamin D status with this advanced at-home test.
Using highly precise LC-MS/MS technology, this test measures both Vitamin D₂ and Vitamin D₃ independently, offering a more complete and reliable assessment than standard testing.
Vitamin D plays a vital role in bone health, immune function, mood regulation, and cardiovascular support. When levels are low or imbalanced, it can contribute to fatigue, weakened immunity, hormone disruption, and long-term health challenges.
Designed for at-home convenience with clinical-level accuracy, this test provides the insight needed to support targeted supplementation and lifestyle choices for optimal health.
Once your results are in, you can schedule a Functional Lab Review where we’ll go through your results together and create a personalized plan to restore and maintain balance.

WEIGHT MANAGEMENT TEST KIT
If you’re doing all the right things and still struggling with weight, your hormones may be the missing piece.
This comprehensive panel is designed to uncover underlying imbalances that can impact metabolism, fat storage, energy, and overall health. Rather than focusing only on diet and exercise, this test helps identify what may be happening beneath the surface.
Hormones play a central role in how your body regulates weight, blood sugar, insulin, and where fat is stored. When these systems are out of balance, it can lead to stubborn weight gain, fatigue, cravings, and difficulty seeing results despite your efforts.
This panel is ideal for both women and men navigating weight challenges, menopause or andropause, PCOS, or anyone looking to better understand the root of their symptoms.
Common patterns this test can help uncover include:
Imbalances in estrogen and progesterone, often linked to water retention and weight gain in the hips and thighs
Low testosterone or DHEA, which can reduce muscle mass and slow metabolism
Elevated cortisol, associated with stress, poor sleep, cravings, and abdominal weight gain
Low cortisol, often connected to fatigue, low energy, and poor recovery
Vitamin D deficiency, which can influence metabolism and fat storage
Thyroid imbalance, impacting metabolic rate and energy
Insulin resistance and blood sugar dysregulation, key drivers of weight gain and metabolic dysfunction
Designed for at-home convenience with clinical-level accuracy, this test offers deeper insight into the hormonal patterns influencing your weight and overall well-being.
Once your results are in, you can schedule a Functional Lab Review where we’ll walk through your results together and create a personalized protocol to support your body in restoring balance.
