Dog Dander IgE

Serum

Allergen Panel

Optimal range:   0 - 0.34 kUA/L

The Dog Dander IgE test measures the specific immune response to proteins found in dog skin flakes, saliva, and urine, collectively known as "dander." IgE, or Immunoglobulin E, is an antibody that your immune system releases when it detects allergens, like dog dander, in sensitive individuals. High levels of Dog Dander IgE suggest that your immune system reacts to these proteins, often causing symptoms like sneezing, itching, or wheezing.

If you experience allergy-like symptoms around dogs, a high Dog Dander IgE result can confirm a sensitivity. Knowing this can guide you in managing exposure and exploring options to reduce symptoms, such as allergy medications or specialized treatments.

DOPAC

ZRT Laboratory (Urinary Neurotransmitters), ZRT Laboratory

Optimal range:   658 - 1449 µg/g creatinine

Dopac (aka 3,4-Dihydroxyphenylacetic acid) is a metabolite of the neurotransmitter dopamine. Dopamine serves as the reward and pleasure center in the brain. DOPAC and HVA (Homovanillic Acid) are dopamine metabolites.

DOPAC levels, when viewed in conjunction with dopamine levels, may provide insight into how the body processes neurotransmitters.

Dopamine

ZRT Laboratory (Urinary Neurotransmitters), ZRT Laboratory

Optimal range:   144 - 240 µg/g creatinine

Dopamine is a chemical found naturally in the human body. It is a neurotransmitter, meaning it sends signals from the body to the brain. Dopamine plays a part in controlling the movements a person makes, as well as their emotional responses. The right balance of dopamine is vital for both physical and mental wellbeing.

Dopamine

Urine

Neuro Basic Profile (Labrix, Doctor's Data), Doctor's Data

Optimal range:   125 - 250 µg/g

Dopamine is largely responsible for regulating the pleasure reward pathway, memory and motor control. Its function creates both inhibitory and excitatory action depending on the dopaminergic receptor it binds to. Memory issues are common with both elevations and depressions in dopamine levels. Caffeine and other stimulants, such as medications for ADD/ADHD, often improve focus by increasing dopamine release, although continual stimulation of this release can deplete dopamine over time.

Dopamine

HPA (NeuroLab), Sanesco Health

Optimal range:   250 - 400 ug/g Cr

Dopamine is a neurotransmitter that activates the brain’s reward center during pleasurable activities.

Optimal dopamine function is involved in many aspects of health, including memory, movement, motivation, mood, attention, sleep, arousal, learning, and lactation.

What is dopamine and what are its functions?

Dopamine is a neurotransmitter (= chemical messenger) that is produced in large concentrations during pleasurable activities such as when eating sugar or junk food, having sex, or participating in fun and enjoyable down-time activities like spending time in nature or engaging in a favorite hobby. Dopamine is released during these times as a reward for engaging in the activities necessary for survival and reproduction such as eating, drinking, and competing.

Catecholamines, Fractionated, Random Urine, Quest Diagnostics

Optimal range:   295 - 1123 mcg/g Cr

In a Catecholamines, Fractionated, Random Urine test, dopamine is one of the catecholamines measured. Catecholamines are a group of hormones and neurotransmitters that include substances like epinephrine (adrenaline), norepinephrine (noradrenaline), and dopamine. These chemicals play essential roles in the body's nervous system and its response to stress.

Dorea

Gut Zoomer by Vibrant Wellness, Vibrant Wellness

Optimal range:   0 - 20 Units

What is Dorea?

Dorea is a genus of bacteria that resides in the human gut as part of the normal intestinal microbiome. It is a Gram-positive, anaerobic bacterium from the Lachnospiraceae family, a group known for producing short-chain fatty acids and fermenting dietary fiber.

Although Dorea is considered a commensal organism (not inherently harmful), its presence and abundance in the gut can offer clues about your digestive efficiency, gas production, inflammation levels, and overall microbial balance.

Dorea is a genus within the Lachnospiraceae family that is in the Firmicutes phylum. Dorea species are known to produce hydrogen and carbon dioxide as end-products of glucose fermentation and may be associated with bloating.

DPA

OmegaCheck, Quest Diagnostics

Optimal range:   0.8 - 1.8 % by wt

Docosapentaenoic acid (DPA) is an omega-3 fatty acid with 22 carbons and five double bonds (22:5n3). It is formed from its precursor, EPA, by way of the elongase enzyme which adds two carbons. It can be supplemented or obtained in the diet from foods such as marine oily fish.

Not only is DPA found in most fish and marine foods but it is also present in lean red meat from ruminant animals.

DPA (RBC)

Micronutrient (Vibrant America), Vibrant America

Optimal range:   0.45 - 1.8 %

The DPA (Docosapentaenoic Acid) test in red blood cells (RBC) offers a comprehensive assessment of DPA levels, a key omega-3 fatty acid. DPA, found in fish oils and marine life, plays a critical role in cardiovascular health, brain function, and inflammation regulation. Measuring DPA levels in RBCs provides a more accurate and long-term indicator of omega-3 status than serum tests, reflecting the body's actual omega-3 fatty acid utilization over time. This is particularly vital for individuals at risk of heart disease, cognitive disorders, or inflammatory conditions.

Dr. Barnes' Basal Temperature Test (BBTT)

Body Temperature Measurements

Optimal range:   97 - 99 F

Dr. Barnes' Basal Temperature Test (BBTT) is a method used to assess thyroid function. It involves measuring the body's basal temperature upon waking. The test is based on the idea that low thyroid function can result in a lower body temperature. According to Dr. Broda Otto Barnes, who developed and promoted the test, a normal reading upon waking is around 97.8 °F (36.6 °C). If the basal temperature consistently deviates from this range, it might indicate an underactive thyroid.

The BBTT is performed by placing a thermometer in the armpit for 10 minutes immediately upon waking. While this test can provide indications of thyroid issues, it's not a definitive diagnostic tool and should be used alongside other assessments. If the test suggests thyroid dysfunction, consult a medical professional for further evaluation and treatment options.
