About Our Diagnostic Assessments

Essential Diagnostics

The essential diagnostic tests to evaluate and begin managing the state of your health.
Advanced Lipid Panel

The panel that leverages advanced cardiovascular and lipid science to provide the health information that everyone should be getting and few have experienced.

Half of heart attack patients in the US have normal standard lipid panels – this critical assessment of your risk of developing cardiovascular disease includes the amount and types of fats in your blood such as cholesterol, triglycerides, high density lipoprotein (HDLC or “good” cholesterol) and low density lipoprotein (LDL-C or “bad” cholesterol) as well as key advanced markers of heart health like LDL-C Direct, Lp(a), Apo A1, Apo B, % small dense LDL (%sd-ldl) that correlate with cardiac risk even in people with normal lipid panels.
Inflammation Biomarkers

This panel measures markers of chronic low-level inflammation which usually don't produce symptoms but are now understood to be related to virtually all health problems.

Chronic low-level inflammation usually doesn’t produce symptoms that you are aware of. However, at the cellular level, it is increasing and accelerating your risks for cardiovascular disease, arthritis, asthma, Alzheimer’s disease, diabetes, colitis, and much much more. Measuring inflammation biomarkers such as high sensitivity Creactive protein (hs-CRP) and lipoprotein-associated phospholipase A2 (Lp-PLA2) is a critical part of assessing an individual’s risk for future diseases.
Vitamin D

Optimal levels of vitamin D are critical for immune function and long-term health. What's your level of vitamin D?

Vitamin D’s benefits go far beyond its ability to regulate the absorption of minerals such as calcium and phosphorus for skeletal health and the prevention of osteoporosis. Scientists recently discovered that most cells contain vitamin D receptors and that vitamin D regulates the activity and function of thousands of genes. Vitamin D helps regulate cellular growth, the activity of nerves and muscles, and many aspects of the immune system. Our body produces vitamin D when bare skin is exposed to sunlight. However, most people do not get enough sunlight exposure. People at greater risk of vitamin D deficiency are infants, African Americans, the elderly and those living at northern latitudes.
Comprehensive Metabolic Panel (CMP)

This panel is a group of 16 specific tests that provide important information about the current status of your kidney and liver function, acid/base balance, blood sugar and blood proteins.

The CMP includes the following:
Glucose
This measures your blood sugar levels. High values are associated with diabetes or prediabetes.
BUN
The BUN (blood urea nitrogen) measures the amount of nitrogen in your blood and assesses kidney function.
Creatinine
is a waste product filtered out of the blood by the kidneys. Elevated levels indicate a temporary or chronic decrease in kidney function.
Sodium
an electrolyte that regulates water & body fluids, nerve conduction (including the heart), blood pressure and pH (acid/base balance).
Potassium
an electrolyte that plays a critical role in regulating blood pressure and the function of nerve and muscle cells, including the heart.
Chloride
an electrolyte that regulates levels of water and body fluids and acid/base balance.
Carbon Dioxide
a blood gas that evaluates your oxygenation and acid/base status. Abnormal levels often indicate breathing problems.
Calcium
a mineral that regulates many important activities, including bone formation, muscle contraction and blood clotting.
Total protein
abnormal levels reflect nutritional status, may indicate malnutrition, and can help diagnose kidney and liver disease
Albumin
the most prevalent protein in blood; regulates osmotic pressure (concentration of water & body fluids) and screens for abnormal liver & kidney function.
Bilirubin
a waste product produced in the liver from the breakdown and recycling of aged red blood cells. Elevated levels indicate excessive destruction of red blood cells, liver disease and/or blockage of the bile ducts.
Globulin
a measure of proteins in the blood. The body uses globulins to make antibodies, clotting factors and other protein-containing compounds in the body.
Alkaline phosphatase
an enzyme found in all body tissues, but primarily in bone and liver. Elevated levels may indicate liver or bone disease.
AST (SGOT)
an enzyme found primarily in the liver and muscles. Elevated levels may indicate liver problems, hepatitis, excess alcohol, muscle injury of recent heart attack.
Complete Blood Count w/ Differential (CBC)

A CBC is an integral part of getting a "snapshot" of your health. It measures the amount of red blood cells, white blood cells and platelets in your blood, and also evaluates the relative condition or health of these cells. The CBC is also used as a broad screening test to check for anemia, infections, and many other diseases.

Premium Diagnostics

The most advanced diagnostics tests to optimize your health.
Genetic Diagnostics

It is also important to realize that an abnormal gene does not necessarily cause a disease. With this information, you can often identify diet, nutritional and lifestyle interventions that can dramatically influence your health risks.

Assessing cardiac genetic markers provides a window into an individual’s risks for a variety of healthrelated risks. These tests measure markers such as Prothrombin Mutation, Factor V Leiden, Warfarin Sensitivity, and the type of genes you have for folic acid metabolism. It is important to learn your genetic profile.
Aspirin Sensitivity

Assesses whether your daily aspirin therapy is being effective to help prevent a heart attack.

Advanced Cardiac Panel

This advanced lipid panel provides more predictive insights into heart health by showing levels of important lipid fractions that correlate with cardiac risk even in people with normal lipid panels.

Maintaining Optimal Hormone Levels

A critical part of healthy aging involves attaining and maintaining optimal levels of key hormones in the body. After age 30, hormone levels begin to decline in most people.

Declining hormone levels are associated with increased risks to heart disease, diabetes, osteoporosis, obesity, elevated blood pressure, and many other diseases. Targeted hormone supplementation is safe and effective, but is critically important to only utilize natural or bioidentical hormones. Our laboratory tests measure the following hormones:
Testosterone (both total and free)
low levels are associated with decreased sex drive, decreased muscle mass and bone density, and fatigue.
Estradiol
the primary estrogenic hormone, produced in both men and women. It regulates reproductive and sexual functioning and also plays a major role in determining things like bone density and cognitive function. Levels in women begin to decline rapidly during peri-menopause and menopause.
Thyroid Hormones
Thyroid hormones regulate your body’s metabolism and low levels can cause fatigue, depression, weight gain and many other problems. Our thyroid panel measures TSH (thyroid stimulating hormone) which is produced in the pituitary gland and signals the thyroid gland to produce thyroid hormones and T4 (thyroxine) and T3 (triiodothyronine).
DHEA (Dehydroepiandrosterone)
called the “mother hormone.” DHEA is the most abundant steroid hormone in the human body, and it is the precursor to many other hormones including estrogen and testosterone. Low levels are associated with stress, diabetes, heart disease, breast cancer, obesity, depression, osteoporosis and Alzheimer’s disease.
SHBG (Sex Hormone Binding Globulin)
binds to testosterone and estradiol so that they can be transported throughout the body.
Bone Markers

Maintaining optimal skeletal health is important for longterm health. We measure various bone markers to assess skeletal health including, alkaline phosphatase (ALP), vitamin D levels (as 24-hydroxy vitamin D), parathyroid hormone levels and osteocalcin.

Tumor Markers

Tumor markers are substances produced in the body when some form of cancer metabolism is active. These markers are used to screen for certain types of cancer and they are also used to evaluate the effectiveness of cancer therapy.

Fatty Acid Index

Fats play critical roles in human health. This test evaluates an individual’s fatty acid profile, assessing levels of “good fats” “bad fats” and the relative amount and ratios of fats in the body.

Fats are the primary component(s) in the structure of cell walls and cellular membranes of every cell in the body. Hence, if you don’t have the right kind of fats and the correct amount and ratio of fats in your body, the activity and function of every cell in your body will be compromised. Key fats also regulate the production of a group of chemicals called eicosanoids. Eicosanoids are master control compounds that regulate a vast amount of activity and function in all cells throughout the body. For example, eicosanoids control blood pressure, blood clotting, cardiovascular function, inflammation, the immune system, and much much more.

With easy to interpet overviews and summaries about specific health markers,
your health is now easier to understand than ever.
