Your annual All Systems Go panel runs 37 test orders that expand into 99+ individual biomarkers β drawn at Quest locations nationwide, physician-reviewed, and included in membership at our cost. Search or browse every one below.
Lipid Panel Lipids & Particles Your foundational cholesterol picture β total, LDL, HDL, and triglycerides.
The standard lipid panel measures total cholesterol, LDL (βbadβ) cholesterol, HDL (βgoodβ) cholesterol, and triglycerides. Itβs the baseline most physicals stop at β we use it as a starting point, then go far deeper with particle-level testing, because cholesterol totals alone miss a large share of cardiovascular risk.
LDL Particle Fractionation (Ion Mobility) Lipids & Particles Counts and sizes your LDL particles, not just the cholesterol inside them.
Standard LDL-C estimates the cholesterol carried by your LDL, but risk tracks with the number and size of the particles themselves. Ion-mobility fractionation counts your LDL particles and measures how small and dense they are β small, dense LDL is more strongly associated with plaque formation than large, buoyant LDL.
Apolipoprotein B (ApoB) Lipids & Particles The single most accurate count of the particles that drive plaque.
Every atherogenic particle carries exactly one ApoB protein, so ApoB is a direct count of the particles that can lodge in your artery walls. Large analyses have found ApoB predicts cardiovascular events better than LDL cholesterol β especially when the two disagree, which is common in metabolic dysfunction. Itβs one of the most important numbers most standard panels never report.
Apolipoprotein A1 (ApoA1) Lipids & Particles The protein backbone of your protective HDL particles.
ApoA1 is the main protein in HDL (βgoodβ) cholesterol and reflects how well your HDL can carry cholesterol away from artery walls. Read alongside ApoB, it helps paint a fuller picture of the balance between plaque-forming and plaque-clearing particles than cholesterol totals alone.
Lipoprotein(a) β Lp(a) Lipids & Particles An inherited, one-time risk marker most people are never tested for.
Lipoprotein(a) is a largely inherited particle that can meaningfully raise cardiovascular risk. It affects roughly 1 in 5 people, yet very few have ever been tested. Because itβs about 90% genetic, a single lifetime measurement usually tells you what you need to know β and itβs almost never part of a standard cholesterol panel.
Oxidized LDL (OxLDL) Lipids & Particles Measures whether your LDL is actively doing damage β not just present.
Oxidized LDL reflects LDL particles that have been chemically damaged and are actively contributing to plaque formation and arterial inflammation. Itβs one of the more direct signals of whether cholesterol is causing harm right now, rather than simply how much is circulating.
Omega 3/6 Panel Lipids & Particles Your omega-3 to omega-6 balance β a lever you can move with diet.
This panel measures key omega-3 (like EPA and DHA) and omega-6 fatty acids and the balance between them. That balance influences inflammation and cardiovascular health, and itβs one of the most responsive markers to dietary change β making it a useful way to track how nutrition shifts are landing.
Hemoglobin A1C Your average blood sugar over the past ~3 months.
A1C reflects your average blood glucose over roughly three months. Because metabolic dysfunction is a major, often-silent driver of heart disease, tracking A1C helps surface insulin resistance and rising blood-sugar trends early β well before theyβd show up as a fasting-glucose problem.
Fasting Insulin Often the earliest signal of insulin resistance, years before glucose rises.
Fasting insulin can climb long before fasting glucose or A1C move, making it one of the earliest windows into insulin resistance β a root driver of cardiovascular and metabolic risk. Standard panels rarely include it, which is why early metabolic dysfunction so often goes unseen. (Paired with glucose, it also lets us calculate HOMA-IR.)
Uric Acid A metabolic marker linked to blood pressure and heart health.
Beyond its role in gout, uric acid is associated with blood pressure, metabolic health, and cardiovascular risk. Elevated levels can reflect underlying metabolic dysfunction, so we track it as part of the fuller metabolic picture.
Comprehensive Metabolic Panel (CMP) 14 markers covering blood sugar, electrolytes, kidney, and liver function.
The CMP is a 14-analyte panel covering fasting glucose, electrolytes (like sodium and potassium), kidney markers (creatinine, eGFR), and liver enzymes (ALT, AST). Itβs a broad safety-and-function check that anchors both your metabolic picture and organ health β one composite order that expands into many individual biomarkers.
hs-CRP Inflammation & Immunity A sensitive marker of the low-grade inflammation behind plaque.
High-sensitivity C-reactive protein detects the low-grade, systemic inflammation that fuels atherosclerosis. Because heart disease is as much an inflammatory process as a cholesterol one, hs-CRP adds risk information a lipid panel canβt β sometimes flagging concern even when cholesterol looks fine.
ESR (Sed Rate) Inflammation & Immunity A general gauge of inflammation across the body.
The erythrocyte sedimentation rate is a long-established, general measure of inflammation. Read alongside more specific markers like hs-CRP, it helps confirm whether an inflammatory process is present and worth understanding further with your care team.
Myeloperoxidase (MPO) Inflammation & Immunity Signals inflammation specifically within the artery wall.
Myeloperoxidase is an enzyme released by active immune cells that points to inflammation within the blood-vessel wall itself β the kind tied to unstable, vulnerable plaque. It adds a vascular-specific layer to the inflammation picture that general markers can miss.
Lp-PLA2 Inflammation & Immunity An enzyme tied specifically to inflamed, plaque-prone arteries.
Lp-PLA2 is an enzyme closely linked to inflammation inside the artery wall and to plaque thatβs more prone to rupture. Unlike broad inflammatory markers, itβs relatively specific to vascular inflammation, helping distinguish arterial risk from general inflammation.
Homocysteine Inflammation & Immunity An amino acid that, when elevated, can injure blood vessels.
Homocysteine is an amino acid that, at elevated levels, is associated with damage to the blood-vessel lining and higher cardiovascular risk. Itβs often influenced by B-vitamin status and methylation, so it can point toward root causes that are addressable through nutrition with your care team.
Antinuclear Antibodies (ANA) Inflammation & Immunity Screens for autoimmune activity that can drive inflammation.
ANA is a screening marker for autoimmune activity. Because autoimmune and inflammatory conditions can quietly contribute to cardiovascular and whole-body risk, we include it to help surface immune drivers that standard cardiac workups overlook.
Rheumatoid Factor (RF) Inflammation & Immunity An immune marker associated with inflammatory conditions.
Rheumatoid factor is an antibody linked to rheumatoid arthritis and other inflammatory conditions. Chronic inflammation of this kind is associated with elevated cardiovascular risk, so it adds another lens on the immune and inflammatory factors that shape heart health.
TSH Hormones & Thyroid The master signal that sets your thyroid β and metabolic β pace.
Thyroid-stimulating hormone is the pituitaryβs signal to the thyroid and the first-line marker of thyroid function. Because thyroid status influences metabolism, cholesterol, and heart rate, an out-of-range TSH can ripple into cardiovascular and metabolic health.
Free T4 Hormones & Thyroid The circulating thyroid hormone available to your tissues.
Free T4 measures the unbound thyroxine available to your cells. Paired with TSH and Free T3, it gives a fuller view of thyroid function than TSH alone β useful because thyroid imbalances can quietly affect cholesterol, weight, and cardiovascular health.
Free T3 Hormones & Thyroid The active thyroid hormone that drives your metabolism.
Free T3 is the most metabolically active thyroid hormone. Measuring it alongside TSH and Free T4 helps reveal how well your body is converting and using thyroid hormone β a factor in energy, metabolism, and heart health that a single TSH can miss.
Thyroid Antibodies (Thyroglobulin + TPO) Hormones & Thyroid Screens for autoimmune thyroid activity behind thyroid dysfunction.
Thyroid antibodies (thyroglobulin and TPO) reveal whether an autoimmune process is affecting your thyroid β the most common cause of thyroid dysfunction. Since thyroid health influences metabolism and cardiovascular risk, catching an autoimmune driver early opens more room to act.
Testosterone (Total & Free) Hormones & Thyroid A key hormone β measured total and bioavailable β tied to metabolic health.
We measure both total testosterone and the free, biologically active fraction. Testosterone influences muscle, metabolism, mood, and cardiovascular health in people of all genders, and because much of it circulates bound and inactive, the free measure often reflects true hormonal status more accurately. Imbalances frequently travel with metabolic dysfunction.
Estradiol Hormones & Thyroid A primary estrogen that influences vascular and metabolic health.
Estradiol is a primary form of estrogen relevant to people of all genders. It plays a role in blood-vessel function, bone, and metabolic health, so itβs part of the hormonal picture that shapes cardiovascular risk over time.
Progesterone Hormones & Thyroid A hormone that helps contextualize overall endocrine balance.
Progesterone helps round out the hormonal picture, particularly for women, and supports interpretation of the broader endocrine balance that intersects with metabolic and cardiovascular health.
DHEA-S Hormones & Thyroid An adrenal hormone reflecting stress resilience and hormonal reserve.
DHEA-S is an adrenal hormone that serves as a building block for other hormones and reflects hormonal reserve and stress physiology. Because chronic stress is a genuine driver of cardiovascular risk, DHEA-S adds insight into that often-overlooked dimension.
SHBG Hormones & Thyroid Controls how much of your sex hormones are actually active.
Sex hormone-binding globulin controls how much of your testosterone and estrogen is bound versus free and active. It also tracks with insulin resistance, so it helps connect hormonal and metabolic health in one measure.
Cortisol (AM) Hormones & Thyroid Your morning stress hormone β a window into chronic stress load.
Cortisol is the bodyβs primary stress hormone, and a morning measurement captures it near its natural daily peak. Chronically dysregulated cortisol is linked to blood pressure, metabolism, and cardiovascular risk, making it a meaningful part of a root-cause picture.
GGT Organ Function A liver enzyme that also flags oxidative stress and metabolic strain.
Gamma-glutamyl transferase is a liver enzyme that, beyond liver health, is associated with oxidative stress and metabolic and cardiovascular risk. Even within βnormalβ ranges, rising GGT can hint at metabolic strain worth understanding.
Amylase Organ Function A pancreatic enzyme included as a broader organ-safety check.
Amylase is an enzyme primarily from the pancreas. Itβs included as part of a thorough organ-function and safety picture, helping ensure the systems around your metabolic health are working as they should.
Lipase Organ Function A pancreatic enzyme that rounds out organ-function screening.
Lipase, another pancreatic enzyme, complements amylase in checking pancreatic and digestive health β part of the comprehensive organ-function screening that surrounds your cardiovascular and metabolic markers. (Your kidney and liver markers are also covered within the Comprehensive Metabolic Panel.)
CBC with Differential Blood & Nutrients A complete blood count covering immune cells, red cells, and platelets.
The complete blood count with differential measures red cells, white cells (and their types), and platelets. Itβs a foundational health and safety panel that can surface anemia, immune activity, and clotting-related factors β one composite order expanding into many individual values.
Iron (Total) Blood & Nutrients Circulating iron, essential for oxygen delivery and energy.
Total iron reflects the iron available for making hemoglobin and delivering oxygen. Both low and high iron can affect cardiovascular and metabolic health, so itβs read alongside ferritin for a fuller iron-status picture.
Ferritin Blood & Nutrients Your bodyβs iron storage β and a sensitive inflammation marker too.
Ferritin reflects stored iron and doubles as an inflammation marker, since it rises with inflammatory activity. That dual role makes it useful for understanding both nutrient status and hidden inflammation.
Vitamin D (25-OH) Blood & Nutrients A widely deficient vitamin tied to vascular and immune health.
25-hydroxyvitamin D is the best measure of vitamin D status. Deficiency is common and associated with cardiovascular, immune, and metabolic health β and because itβs so responsive to supplementation and sunlight, itβs a highly actionable marker to track.
Vitamin B12 Blood & Nutrients Essential for nerves, red blood cells, and homocysteine control.
Vitamin B12 supports nerve function, red-blood-cell formation, and healthy homocysteine metabolism. Low B12 can raise homocysteine and cause fatigue, so it connects nutrient status to cardiovascular risk in a very addressable way.
Folate (Serum) Blood & Nutrients A B vitamin central to methylation and homocysteine balance.
Folate works with B12 to keep homocysteine in a healthy range and support methylation β the biochemistry behind many root-cause pathways. Itβs a nutrient lever thatβs straightforward to correct once measured.
RBC Magnesium Blood & Nutrients A cell-level magnesium reading tied to rhythm and blood pressure.
Measuring magnesium inside red blood cells reflects tissue stores more accurately than a standard serum test. Magnesium supports heart rhythm, blood pressure, and metabolic health, making adequate levels quietly important for cardiovascular wellbeing.
CoQ10 Blood & Nutrients A cellular-energy antioxidant important for the heart muscle.
Coenzyme Q10 helps your cells β especially energy-hungry heart muscle β produce energy and acts as an antioxidant. Levels can fall with age and with certain medications like statins, so measuring it helps ensure this heart-supporting nutrient stays where you want it.
No tests match your search. Try a marker name like ApoB, thyroid, or inflammation.

Cardiac CT β Without the Hassle
Included with Membership Β· Scan Fee Paid Directly to the Facility
Getting a Coronary CT Angiography (CCTA) requires a physician order β and most doctors won't write one. That's why the CCTA Concierge is one of the biggest benefits of joining the 90 Nation: every member gets an annual Physician Chart Review β every membership year, a licensed physician at 3 Billion Beats Medical, PA, the independent physician practice we contract with, personally reviews your chart β your labs, history, and risk factors β to determine whether a CCTA is right for you. It's a records-based review, not a video visit: nothing to schedule, no waiting room. When a CCTA is clinically appropriate, your physician orders it and the concierge handles everything else β insurance coordination, facility discovery, and appointment scheduling. If it isn't indicated this year, your physician explains why and what we'll watch in your labs. Direct-to-consumer imaging services charge $500β$1,200 just for the physician review that gets a CCTA ordered; yours is included. The scan itself is the one cost outside your membership β paid directly to the facility, and your insurance may cover it.
