Additional Information


Dried Urine Tests

How a Dysregulated Nervous System Impacts Health
Genetics, environment, chemicals and nutritional deficiencies are a few factors that can impact neurotransmitter production. Once out of balance, the nervous system begins to compensate – which, in time, can lead to neurological or psychological symptoms.

Some of the more common psychological conditions today are known to be accompanied by neurotransmitter imbalances. However, it’s also possible for individuals to present with similar symptoms yet have unique foundational imbalances. Testing helps clarify these root issues.

Common neurotransmitter-related causes of health issues often involve the following scenarios:
Anxiety & Depression
Chronic Fatigue

Most Convenient Method for Urine Testing
ZRT’s dried urine method offers a discreet, at-home testing alternative and eliminates the hassles of all-day jug urine collection. Patients collect urine on a filter strip up to four times during the day. Dried strips are shelf-stable for 30 days and easy to mail back to the lab for analysis.

Sleep Balance

Chronic sleep problems resulting in longer-term HPA axis dysregulation and deficiencies in melatonin production can impact multiple aspects of overall health. Melatonin is a potent free radical scavenger and protects against diseases related to premature aging, as well as cancer and cardiovascular disease.

ZRT Laboratory has developed a melatonin and cortisol dried urine test that circumvents the disadvantages of serum, saliva, and 24-hour urine tests commonly used for testing these hormones.

Menstrual Cycle Mapping Profile
E1G, PDG, LH & Crtn
A month-long assessment of a woman’s key reproductive hormones.
Evidence shows that hormonal imbalances can be the root cause of many chronic health issues, and imbalances that affect a woman’s menstrual cycle are no exception.

Conditions that can be influenced by a woman’s menstrual hormones include premenstrual syndrome (PMS), premenstrual dysphoric disorder (PMDD) and infertility. Out-of-balance levels can contribute to symptoms such as migraines, mood swings, and heavy bleeding or painful periods.

When hormone testing conducted on a single day during the luteal phase doesn’t provide enough diagnostic information, a month-long hormone assessment can be helpful. This detailed, multi-point map provides a complete picture of a woman’s levels over the course of one menstrual cycle resulting in the ability to create more precise treatment plans.

Menstrual cycle mapping can by key to assessing conditions such as:
Luteal Phase Defect
Premenstrual Syndrome

Who Can Benefit from Menstrual Cycle Mapping?
This testing is ideal for cycling women who are interested in knowing key hormone levels throughout the month – either as a way of getting to the root of difficult menstrual symptoms, assessing cases of PMS/PMDD or learning more about their fertility.

This testing is not designed for women who are on birth control, supplementing with hormones or post menopausal.

Those who want the most comprehensive picture of fertility hormone levels should ask their health care provider about using both profiles in combination.
