Presence of meat fibers is indicative of improper chewing or digestive insufficiency.

Meat-glue, a combination of transglutaminase with other ingredients, is used to turn small pieces of meat into larger pieces of meat.

MeFOSAA (Methylperfluorooctane sulfonamidoacetic acid) is one of the 9 specific PFAS (Forever Chemicals) measured in the PFAS (Forever Chemicals) 9 Panel by Quest Diagnostics. It is a chemical compound that belongs to the family of perfluorinated alkyl substances (PFAS), which are synthetic chemicals known for their resistance to heat, water, oil, and stains. These unique properties make PFAS useful in a wide range of consumer products, but their persistence in the environment and human body has raised concerns about potential health risks.

Melanocyte-Stimulating hormone (MSH) characterizes a group of hormones made by the pituitary gland, hypothalamus, and skin cells. MSH is essential for preserving the skin from ultraviolet rays, the development of pigmentation, and controlling appetite. 

Melatonin is a hormone that is produced from the pineal gland in a circadian pattern and plays a role in the initiation of sleep.

The production and release of this hormone is connected to the time of day, ideally increasing when it is dark and decreasing when it is light. Melatonin and cortisol follow opposite circadian patterns but are not cross-regulated in a negative feedback manner.

The production of melatonin decreases with age.

Treatment with melatonin may be useful in people with circadian rhythm sleep disorders, such as delayed sleep phase disorder, jet lag, shift worker disorder, and the non-24-hour sleep-wake disorder most commonly found in totally blind individuals.

Melatonin is not technically an adrenal or sex hormone however it is highly involved in the entire endocrine system. It is made in small amounts in the pineal gland in response to darkness and stimulated by Melanocyte Stimulating Hormone (MSH). 

Melatonin (1st Morning), a crucial marker of sleep-wake cycle regulation and overall well-being, is a key component of the ZRT Laboratory Urinary Neurotransmitters panel, highlighting its significance in both sleep medicine and general health monitoring. Melatonin, often referred to as the "sleep hormone," is produced by the pineal gland in the brain and plays a vital role in regulating the body's circadian rhythm. The measurement of first morning melatonin levels provides invaluable insights into an individual’s sleep quality and circadian rhythm health.

Melatonin (2nd Morning), a pivotal marker in the ZRT Laboratory Urinary Neurotransmitters panel, offers essential insights into an individual’s sleep-wake cycle and overall neuroendocrine health. This hormone, predominantly secreted by the pineal gland during darkness, is crucial for regulating circadian rhythms and promoting restful sleep. The measurement of melatonin levels on the second morning provides a unique perspective on the body's ability to maintain stable melatonin production across multiple sleep cycles.

Melatonin (Evening), a critical biomarker in the ZRT Laboratory Urinary Neurotransmitters panel, plays an instrumental role in assessing nocturnal melatonin production and understanding sleep-wake cycle disturbances in individuals. Melatonin, often called the 'darkness hormone', is naturally produced by the pineal gland in response to darkness, peaking during the night to regulate sleep patterns and circadian rhythms. The measurement of evening melatonin levels provides valuable insights into the body’s readiness for sleep and its ability to enter a restful state.

Melatonin (Night), a key indicator of sleep health and circadian rhythm, is a prominent marker in the ZRT Laboratory Urinary Neurotransmitters panel, underscoring its crucial role in evaluating nocturnal melatonin activity and overall well-being. Melatonin, known as the "sleep hormone," is produced by the pineal gland and is critical for regulating the sleep-wake cycle and maintaining the body's internal clock. Nighttime measurements of melatonin provide essential insights into an individual's natural sleep patterns and the effectiveness of their circadian rhythms.

Melatonin is not technically an adrenal or sex hormone however it is highly involved in the entire endocrine system. It is made in small amounts in the pineal gland in response to darkness and stimulated by Melanocyte Stimulating Hormone (MSH). A low MSH is associated with insomnia, an increased perception of pain, and mold exposure. Pineal melatonin (melatonin is also made in significant quantities in the gut) is associated with the circadian rhythm of all hormones (including female hormone release). It is also made in small amounts in the bone marrow, lymphocytes, epithelial cells and mast cells. Studies have shown that a urine sample collected upon waking has levels of 6-Hydroxymelatonin-sulfate (6-OHMS) that correlate well to the total levels of melatonin in blood samples taken continuously throughout the night. The DUTCH test uses the waking sample only to test levels of melatonin production. Low melatonin levels may be associated with insomnia, poor immune response, constipation, weight gain or increased appetite. Elevated melatonin is usually caused by ingestion of melatonin through melatonin supplementation or eating melatonin-containing foods. Elevated melatonin production that is problematic is rare, but levels can be higher in patients with Chronic Fatigue Syndrome and may be phase shifted (peaking later) in some forms of depression.

The urinary level of mercapturic acids indicates quantitatively the degree of activity or capability of phase II detoxification. Mercapturic acids are the final excretory products of detoxification and include a variety of functionalized xenobiotics that have been conjugated with glutathione or L-cysteine prior to excretion. When the rate of formation of functionalized xenobiotics (phase I) exceeds the capacity of phase II detoxification, more potent toxins accumulate.

Fecal mercury (Hg) provides a good indication of recent or ongoing exposure to elemental Hg, and to a much lesser extent Hg that has been excreted from the body in bile. Data collected at Doctor’s Data indicates a linear association between fecal Hg concentration and the number of amalgams currently in the mouth. Fecal Hg for subjects with 9 to 11 dental amalgams in place was 20-times greater than that
of subjects without any dental amalgams in place (0.60 and 0.03 g/gram dry weight, respectively). Dental amalgams typically contain about 50% elemental Hg, and constant abrasion associated with chewing and bruxism releases very small particles of Hg which are poorly absorbed (about 5%) in the gastrointestinal tract. A direct association between fecal Hg levels and health has not been established, but a land mark study of amalgam placement in monkeys indicated there was an associated induction of co-resistance to both Hg and antibiotics by pathogenic bacteria in the gastrointestinal tract, particularly for species in the Enterobacteriaceae family. Such was also reported for miners exposed to elemental Hg while working in gold mines.
