Heart
This category focuses on understanding how well your cardiovascular system is functioning, going beyond a traditional cholesterol panel. We assess blood fats, circulation, and markers of arterial health to identify early risks and support long-term heart wellness.
The overall amount of cholesterol in your blood (A combination of LDL and HDL)
Often referred to as "bad" cholesterol. High levels can lead to plaque buildup in arteries.
Known as "good" cholesterol. It helps remove excess cholesterol from your bloodstream.
A type of fat in your blood. High levels are linked to metabolic health issues.
Measures how many LDL particles you have. A higher number is more predictive of heart disease risk than just LDL cholesterol alone.
Smaller, dense LDL particles are considered more harmful because they’re more likely to penetrate artery walls and contribute to plaque buildup.
Average size of your LDL particles. Larger particles are considered less risky.
Measures how many HDL particles are present. More is generally better.
Very-low-density lipoproteins carry triglycerides. Elevated levels are linked to increased cardiovascular risk.
A protein involved in clearing cholesterol from the bloodstream. Higher levels are generally protective for heart health.
A protein found in LDL (“bad”) cholesterol particles. Elevated levels are linked to a higher risk of plaque buildup and cardiovascular disease.
Nutrients
Even small deficiencies can make a big impact. We evaluate your nutrient stores that support biochemical processes necessary for immunity, cognition, metabolism, and performance.

Important for cell repair, DNA production, and red blood cell formation. Especially critical during times of growth or healing.
A powerhouse mineral involved in hundreds of body processes, including muscle function, relaxation, and steady energy levels.
Tells us how much iron is circulating in your blood. It’s essential for oxygen transport, focus, and endurance.
Reflects how much iron your body has stored. Low levels may suggest deficiency, while high levels could point to inflammation or overload.
Stress & Aging
Helps us understand how your body is responding to daily stress and the aging process. These markers guide interventions for resilience and longevity.
Often called the “stress hormone,” cortisol helps regulate your energy, blood sugar, and inflammation. Abnormal levels can indicate burnout, chronic stress, or adrenal dysfunction.
A marker related to growth hormone activity. It plays a role in cell repair, recovery, and healthy aging.
A hormone involved in stress response, hormone balance, and brain function. Levels naturally decline with age, but low levels may also reflect chronic stress or fatigue.
Female Health
Explores hormone rhythms, fertility, and mood regulation. These insights are key to supporting women through all life stages, from menstruation to menopause.
Regulates your menstrual cycle and supports ovarian function. Often tested to assess fertility and hormone balance.
Works with FSH to trigger ovulation and support the production of progesterone. Imbalances may impact cycle regularity or fertility.
The main form of estrogen in women, essential for regulating the menstrual cycle, supporting bone density, skin health, and emotional well-being.
Offers a broader view of overall estrogen levels in the body and can help assess hormonal shifts throughout different life stages.
A key hormone that balances estrogen, supports a healthy menstrual cycle, and is critical for pregnancy. Low levels may contribute to PMS, irregular cycles, or mood changes.
Influences menstrual regularity, libido, and fertility.
A protein that controls how much estrogen and testosterone are available for your body to use. Imbalances can affect hormone symptoms.

A form of estrogen that’s important for bone density, mood stability, and cardiovascular health in men. Elevated levels can contribute to fatigue, weight gain, or estrogen dominance symptoms.
Provides a broader view of overall estrogen levels, which impact metabolism, libido, and body composition.
A protein that binds to sex hormones like testosterone, regulating how much is available for your body to use.
Total testosterone shows overall hormone levels, while free testosterone reveals how much is active and available. Both are essential for strength, motivation, and sexual health.
A potent form of testosterone involved in muscle growth, libido, and hair development. Imbalances may contribute to hair loss or prostate concerns.
A protein made by the prostate gland. While low levels are normal, higher levels may indicate inflammation, enlargement, or in some cases, risk for prostate cancer. This test helps monitor prostate health over time.
Autoimmunity
Screens for early signs of autoimmune activity, which is when the immune system starts attacking the body’s own tissues. This is often traceable before symptoms fully develop.
Helps detect early signs of autoimmune activity. A positive result may indicate that the immune system is mistakenly attacking healthy tissues.
Commonly used to screen for autoimmune conditions that affect the joints and connective tissue, such as rheumatoid arthritis.
Indicates whether the immune system is targeting the thyroid. Elevated levels are often seen in conditions like Hashimoto’s thyroiditis.
Immune Regulation
Looks at how well your immune system is functioning overall. It helps us identify imbalances that may increase susceptibility to illness or chronic conditions.

These are your body's first responders to bacterial infections. They help fight off illness quickly.
Key players in defending against viruses and helping regulate your immune system.
Help clean up debris from infections and are involved in longer-term immune responses.
Often elevated in people with allergies or in response to certain parasites.
Play a role in allergic reactions and inflammation by releasing histamine.
Inflammation
Chronic inflammation is a root cause of many modern illnesses. We evaluate your body’s baseline inflammatory state so we can reduce internal stress and promote healing.
A sensitive marker that shows low levels of inflammation in the body. Even slight elevations can signal increased risk for chronic conditions like heart disease or autoimmune issues.
An amino acid that, when elevated, can contribute to inflammation and damage blood vessels. It’s also linked to heart health, brain function, and methylation pathways.
Cancer Detection
Select markers help identify early changes that may signal a need for further evaluation. Used as part of a broader prevention strategy.
A marker sometimes used to monitor breast cancer. It may be elevated in active disease but is not used for early screening.
A general tumor marker that may be elevated in several cancers, especially of the colon and rectum.
Most commonly associated with pancreatic and gastrointestinal cancers.
Heavy Metals
Assesses toxic load from environmental exposures. High levels of metals like mercury can interfere with brain function, hormones, and detox capacity.
A toxic heavy metal that can build up in the body from environmental exposure. Even low levels can affect brain function, mood, and long-term health, especially in children and adults with chronic exposure.
An essential mineral that supports immune health, wound healing, hormone balance, and brain function. Both low and high levels can create imbalance.
Another essential mineral that works with zinc to support energy production and the nervous system. Imbalances can affect mood, immunity, and metabolism.
