What's Included

66* biomarkers across 5 categories - click any category to see what's included and why it matters.

  • EPA+DPA+DHA

    The combined total of the three key omega-3 fatty acids in your blood, a summary marker of overall omega-3 status.

  • EPA

    Eicosapentaenoic acid, an anti-inflammatory omega-3 fatty acid found in fish oil.

  • DHA

    Docosahexaenoic acid, an omega-3 fatty acid essential for brain and eye health.

  • DPA

    Docosapentaenoic acid, an omega-3 fatty acid that supports cardiovascular health.

  • Omega-6 Total

    The combined total of omega-6 fatty acids in your blood; important in moderation, but excess relative to omega-3 is linked to inflammation.

  • Omega-3 Total

    The combined total of omega-3 fatty acids in your blood, linked to reduced inflammation and cardiovascular risk.

  • Linoleic Acid (LA)

    The most common omega-6 fatty acid in the Western diet, a precursor to other omega-6 compounds.

  • Arachidonic Acid (AA)

    An omega-6 fatty acid involved in inflammation signaling; balance with EPA is often used as an inflammation marker.

  • Arachidonic Acid/EPA Ratio

    A calculated ratio comparing a pro-inflammatory omega-6 fatty acid to an anti-inflammatory omega-3 fatty acid, used as an inflammation balance marker.

  • Omega-6/Omega-3 Ratio

    A calculated ratio reflecting the balance between omega-6 and omega-3 fatty acids in your diet; lower ratios are generally associated with less inflammation.

  • Total Cholesterol

    The combined measure of all cholesterol carried in your blood, used as a baseline cardiovascular risk marker.

  • Triglycerides

    A type of fat in your blood; elevated levels are linked to cardiovascular risk and often reflect diet, alcohol intake, or insulin resistance.

  • HDL Cholesterol

    "Good" cholesterol that helps clear excess cholesterol from your bloodstream; higher levels are generally protective.

  • LDL Cholesterol (calculated)

    "Bad" cholesterol that can build up in artery walls; typically calculated from your other lipid values rather than measured directly.

  • Cholesterol/HDL Ratio

    A calculated ratio of total cholesterol to HDL, used as an additional cardiovascular risk indicator.

  • Non-HDL Cholesterol

    Total cholesterol minus HDL, capturing all the potentially artery-clogging cholesterol particles in one number.

  • Vitamin D

    The storage form of vitamin D measured in blood tests; essential for bone health, immune function, and mood regulation, and one of the most common nutrient deficiencies.

  • Vitamin B12

    Essential for nerve function, red blood cell production, and DNA synthesis; deficiency can cause fatigue, brain fog, and nerve damage.

  • Folate

    A B vitamin essential for cell division and DNA synthesis; low levels are linked to fatigue, anemia, and elevated homocysteine.

  • Serum Iron

    The amount of iron currently circulating in your blood.

  • TIBC (Total Iron Binding Capacity)

    Measures your blood's capacity to carry iron, used alongside iron and ferritin to distinguish between iron deficiency and other causes of anemia.

  • % Transferrin Saturation

    A calculated percentage showing how much of your iron-transport protein (transferrin) is currently carrying iron, used to help diagnose iron deficiency or overload.

  • Ferritin

    Reflects your body's stored iron levels; low levels indicate iron deficiency, while high levels can signal inflammation or iron overload.

  • Glucose

    Your blood sugar level at the time of the draw; the basic screening marker for diabetes and prediabetes.

  • BUN

    Blood Urea Nitrogen — a waste product filtered by the kidneys; used alongside creatinine to assess kidney function.

  • Creatinine

    A muscle breakdown product filtered by the kidneys; the primary marker used to assess kidney function.

  • eGFR

    Estimated Glomerular Filtration Rate — a calculated estimate of how well your kidneys are filtering blood, derived from creatinine, age, and sex.

  • Sodium

    An electrolyte that regulates fluid balance, nerve function, and blood pressure.

  • Potassium

    An electrolyte essential for heart rhythm, muscle function, and nerve signaling.

  • Chloride

    An electrolyte that works with sodium to maintain fluid balance and acid-base status.

  • CO2

    Carbon dioxide (bicarbonate) level, used to assess your body's acid-base balance.

  • Calcium

    Essential for bone health, muscle function, nerve signaling, and blood clotting.

  • Total Protein

    The combined amount of albumin and globulin in your blood, a general marker of nutrition and liver/kidney health.

  • Albumin

    A protein made by the liver that maintains fluid balance and transports hormones and nutrients through the blood.

  • Globulin

    A group of proteins involved in immune function and blood clotting; calculated as Total Protein minus Albumin.

  • Albumin/Globulin Ratio

    A calculated ratio of albumin to globulin, used to help identify liver disease, kidney disease, or chronic inflammation.

  • BUN/Creatinine Ratio

    A calculated ratio that helps distinguish between different causes of kidney function changes, such as dehydration versus kidney damage.

  • Total Bilirubin

    A byproduct of red blood cell breakdown, processed by the liver; elevated levels can indicate liver or bile duct issues.

  • ALP

    Alkaline Phosphatase — an enzyme from the liver and bones; elevated levels can indicate liver, bile duct, or bone conditions.

  • AST

    Aspartate Aminotransferase — a liver enzyme; elevated levels can indicate liver stress or damage.

  • ALT

    Alanine Aminotransferase — a liver enzyme considered more specific to liver health than AST.

  • Fasting Insulin

    Measures insulin levels after fasting; elevated levels are one of the earliest signs of insulin resistance, often appearing years before blood sugar becomes abnormal.

  • HbA1c (Hemoglobin A1c)

    Reflects your average blood sugar over the past 2-3 months, used to screen for and monitor prediabetes and diabetes.

  • WBC

    White blood cell count — your immune system's front line; elevated or low levels can indicate infection, inflammation, or bone marrow issues.

  • RBC

    Red blood cell count; abnormal levels point toward anemia or other blood disorders.

  • Hemoglobin

    The oxygen-carrying protein inside red blood cells; the standard measure used to diagnose anemia.

  • Hematocrit

    The percentage of your blood volume made up of red blood cells; used alongside hemoglobin to assess anemia and hydration status.

  • MCV

    Mean Corpuscular Volume — the average size of your red blood cells, used to classify the type of anemia if one is present.

  • MCH

    Mean Corpuscular Hemoglobin — the average amount of hemoglobin per red blood cell.

  • MCHC

    Mean Corpuscular Hemoglobin Concentration — the average concentration of hemoglobin within red blood cells.

  • RDW

    Red Cell Distribution Width — measures variation in red blood cell size; an early indicator of nutrient deficiencies before anemia fully develops.

  • Platelet Count

    The number of platelets in your blood, responsible for clotting; too few or too many can affect bleeding and clotting risk.

  • MPV

    Mean Platelet Volume — the average size of your platelets, which can indicate how actively your bone marrow is producing them.

  • Neutrophils %

    The percentage of white blood cells that are neutrophils, your primary defense against bacterial infection.

  • Lymphocytes %

    The percentage of white blood cells that are lymphocytes, key players in fighting viral infections and long-term immunity.

  • Monocytes %

    The percentage of white blood cells that are monocytes, which clean up damaged tissue and fight chronic infection.

  • Eosinophils %

    The percentage of white blood cells that are eosinophils, typically elevated with allergies or parasitic infections.

  • Basophils %

    The percentage of white blood cells that are basophils, involved in allergic and inflammatory responses.

  • Neutrophils Abs

    The absolute count of neutrophils in your blood, rather than a percentage.

  • Lymphocytes Abs

    The absolute count of lymphocytes in your blood, rather than a percentage.

  • Monocytes Abs

    The absolute count of monocytes in your blood, rather than a percentage.

  • Eosinophils Abs

    The absolute count of eosinophils in your blood, rather than a percentage.

  • Basophils Abs

    The absolute count of basophils in your blood, rather than a percentage.

  • hs-CRP (high-sensitivity C-Reactive Protein)

    A sensitive marker of low-grade inflammation in the body, widely used to assess cardiovascular risk beyond cholesterol alone.

  • Magnesium

    Involved in energy production, muscle and nerve function, and hundreds of enzymatic reactions; a standard blood test that gives only a limited snapshot since most magnesium is stored inside cells, not in the bloodstream.

  • Zinc

    An essential trace mineral involved in immune function, wound healing, and hormone production, including testosterone.

*Every result that appears on your official lab report, calculated values included, nothing invented to inflate the count. Conditional add-on tests that only run if an initial result is abnormal aren't counted. How we count →

Why It Matters

Most people who take supplements never actually check whether they're working - they just keep taking them and hope. This panel re-tests the exact markers your supplements are meant to move, so you can see in black and white whether your stack is doing anything or whether it's time to adjust it.

Some testing companies count every calculated ratio and derived index as its own separate "biomarker," so a modest panel gets marketed as having 100+ biomarkers. We count every result that actually appears on your lab report - including calculated values like ratios, since those are real numbers you'll see and can verify yourself - but we don't add anything that isn't genuinely part of what gets reported, and we don't count conditional add-on tests that only run if an initial result comes back abnormal. The number you see is the number of results you'll actually get back, and you can count them yourself on your own report.
