With physician-reviewed results, CLIA-certified labs, and the option for at-home blood draws, Superpower is designed for people who want clarity, convenience, and real accountability - all in one place.

Key benefits of Atherogenic Coefficient testing

  • Flags your cardiovascular risk by comparing harmful to protective cholesterol types.
  • Spots early imbalance before plaque buildup or heart disease symptoms appear.
  • Guides lipid-lowering treatment decisions alongside your total cholesterol and LDL levels.
  • Tracks how well lifestyle changes or medications are rebalancing your cholesterol.
  • Clarifies whether borderline cholesterol numbers pose real cardiovascular threat or not.
  • Protects long-term heart health by identifying hidden risk in metabolic syndrome.
  • Best interpreted with a full lipid panel and your personal risk factors.

What is Atherogenic Coefficient?

The atherogenic coefficient is a calculated ratio that compares "bad" cholesterol to "good" cholesterol in your blood. It divides total cholesterol (or sometimes non-HDL cholesterol) by HDL cholesterol, the protective type that carries cholesterol away from artery walls back to the liver for disposal.

This ratio was developed to capture cardiovascular risk more precisely than looking at total cholesterol alone. A higher coefficient suggests that harmful cholesterol particles outnumber the protective ones, creating conditions that favor plaque buildup inside arteries (atherosclerosis).

A snapshot of cholesterol balance

The coefficient reflects the balance between cholesterol delivery to tissues and cholesterol removal from circulation. When delivery exceeds removal, excess cholesterol can accumulate in artery walls.

Why ratios matter more than absolutes

Absolute cholesterol numbers don't tell the whole story. Someone with moderately elevated total cholesterol but robust HDL may have lower risk than someone with average total cholesterol but very low HDL.

A tool, not a diagnosis

The atherogenic coefficient helps clinicians assess cardiovascular risk patterns. It complements other lipid markers and clinical factors to guide prevention strategies.

Why is Atherogenic Coefficient important?

The atherogenic coefficient estimates your cardiovascular risk by comparing cholesterol that clogs arteries to cholesterol that clears them. It's calculated by dividing total cholesterol minus HDL by HDL itself, revealing how balanced - or imbalanced - your lipid transport system is. Lower values, typically below 3, suggest your body is efficiently removing cholesterol from vessel walls, while higher numbers signal accumulation and inflammation that silently damage your heart and brain.

When your arteries stay clean

Values under 3 reflect a protective lipid profile where HDL cholesterol is abundant enough to shuttle excess cholesterol back to the liver for disposal. This reduces plaque formation in coronary and carotid arteries, lowering stroke and heart attack risk. You're less likely to experience chest pain, claudication, or cognitive decline tied to poor circulation.

When plaque begins to build

Coefficients above 4 or 5 indicate that atherogenic lipoproteins - primarily LDL and VLDL - are overwhelming your reverse transport capacity. Cholesterol deposits thicken artery walls, narrowing blood flow to the heart, kidneys, and extremities. Over time, this drives hypertension, angina, erectile dysfunction in men, and accelerates vascular aging in postmenopausal women who lose estrogen's protective effects.

The long view on vascular health

This ratio integrates multiple lipid signals into one snapshot of endothelial stress and systemic inflammation. It complements standard cholesterol panels by highlighting functional imbalance rather than isolated numbers. Tracking it over years helps predict not just cardiac events but also dementia, peripheral artery disease, and metabolic syndrome progression.

What do my Atherogenic Coefficient results mean?

Low atherogenic coefficient values

Low values usually reflect a favorable lipid profile with high protective HDL cholesterol relative to total cholesterol. This pattern suggests efficient reverse cholesterol transport, where HDL actively removes cholesterol from arterial walls and delivers it to the liver for clearance. A low coefficient typically indicates lower cardiovascular risk and better metabolic health. Women generally have lower values than men due to higher baseline HDL levels, particularly during reproductive years when estrogen supports HDL production.

Optimal atherogenic coefficient range

Being in range suggests balanced cholesterol metabolism with adequate HDL protection relative to total cholesterol burden. Most labs define optimal as a coefficient below 3.0 to 4.0, though cardiovascular risk increases progressively even within the reference range. Lower values within the normal range generally reflect better arterial health and more efficient lipid clearance systems.

High atherogenic coefficient values

High values usually reflect either elevated atherogenic lipids (LDL and VLDL) or insufficient protective HDL, or both. This imbalance indicates increased cholesterol deposition in arterial walls with inadequate reverse transport. Common drivers include insulin resistance, metabolic syndrome, chronic inflammation, and sedentary patterns. Men and postmenopausal women tend toward higher values as protective hormonal influences decline.

Factors that influence interpretation

The coefficient responds to acute illness, which temporarily lowers HDL and raises the ratio. Pregnancy typically improves the ratio in early trimesters before physiologic lipid elevation occurs. Calculation methods vary slightly between labs depending on whether VLDL is measured or estimated.

Method: Derived from FDA-cleared laboratory results. This ratio/index is not an FDA-cleared test. It aids clinician-directed risk assessment and monitoring and is not a stand-alone diagnosis. Inputs: Total-C, HDL-C.

Frequently Asked Questions about Atherogenic Coefficient Test

What is the atherogenic coefficient blood test and how is it calculated from a lipid panel?

The atherogenic coefficient is a calculated cholesterol ratio, not a substance measured directly. It summarizes cholesterol balance by comparing atherogenic (plaque-forming) cholesterol to protective HDL cholesterol. Depending on the lab, it may be calculated as total cholesterol ÷ HDL, or as (total cholesterol − HDL) ÷ HDL (a non‑HDL to HDL approach). It’s best interpreted alongside a full lipid panel and personal cardiovascular risk factors.

Why does the atherogenic coefficient matter for cardiovascular risk beyond LDL cholesterol?

The atherogenic coefficient estimates whether your lipid profile favors cholesterol buildup in arteries or cholesterol clearance by HDL. Unlike LDL alone, this ratio reflects the overall balance between harmful lipoproteins (often represented by non‑HDL) and protective HDL. A higher ratio suggests more plaque-building momentum and higher risk of atherosclerosis, heart attack, and stroke over time - even when total cholesterol looks “normal.”

What is considered an optimal atherogenic coefficient range, and what numbers are “high”?

Many labs consider values below about 3.0 to 4.0 as optimal, with lower generally indicating better protection. Higher ratios - often above 4.0 or 5.0 - suggest atherogenic particles dominate over HDL, increasing long-term cardiovascular risk. Because calculation methods vary by lab, always compare your result to that lab’s reference range and interpret it with the rest of your lipid panel and risk profile.

What does a low atherogenic coefficient mean for heart health and cholesterol transport?

A low atherogenic coefficient usually indicates a favorable lipid balance, with relatively higher HDL compared with total or non‑HDL cholesterol. This supports efficient reverse cholesterol transport, where HDL helps remove cholesterol from artery walls and deliver it to the liver for clearance. Low ratios are commonly associated with better metabolic health, lower inflammation, more resilient blood vessels, and reduced long-term risk for atherosclerosis and cardiovascular disease.

What does a high atherogenic coefficient mean, and can it be serious even without symptoms?

A high atherogenic coefficient often reflects low HDL, high total cholesterol/non‑HDL cholesterol, or both. It suggests impaired cholesterol clearance and increased likelihood of cholesterol depositing in vessel walls, driving atherosclerosis. Many people have no early symptoms, so the risk can be “silent” while circulation and vessel health gradually worsen. High ratios are commonly linked with insulin resistance, metabolic syndrome, chronic inflammation, and sedentary lifestyle patterns.

How can the atherogenic coefficient detect hidden risk when total cholesterol is borderline?

Borderline total cholesterol can be misleading if HDL is low, because the overall balance may still favor plaque formation. The atherogenic coefficient clarifies whether borderline numbers represent a true cardiovascular threat by expressing harmful cholesterol relative to protective HDL. This can help identify early imbalance before plaque buildup or heart disease symptoms appear, especially in people with metabolic syndrome or insulin resistance where “normal” totals may hide higher risk.

How is the atherogenic coefficient used to guide lipid-lowering treatment decisions?

Clinicians may use the atherogenic coefficient as an additional signal when deciding whether lifestyle changes or lipid-lowering medication is warranted, alongside total cholesterol and LDL results. Because it reflects the balance between non‑HDL (atherogenic) and HDL (protective) cholesterol, it can highlight persistent risk even if LDL looks acceptable. It’s most useful when interpreted with a full lipid panel and individual risk factors.

How can I track whether diet, exercise, or medications are improving my atherogenic coefficient?

Tracking the atherogenic coefficient over time can show whether interventions are rebalancing cholesterol - either by lowering total/non‑HDL cholesterol, raising HDL, or both. Because it’s a ratio, improvements may reflect better lipid transport, reduced inflammatory signaling, and healthier vessel function. It’s often used to monitor progress alongside repeat lipid panels to understand whether lifestyle changes or medications are shifting long-term cardiovascular risk.

Why do some labs report different atherogenic coefficient formulas, and does that change interpretation?

Yes. Some labs calculate the ratio as total cholesterol ÷ HDL, while others use (total cholesterol − HDL) ÷ HDL or a non‑HDL ÷ HDL approach. These produce different numeric values, so you should not directly compare results from different labs without noting the formula. The overall interpretation is similar: higher ratios indicate more atherogenic dominance; lower ratios suggest stronger HDL protection. Always use the lab’s reference range.

What factors can temporarily affect atherogenic coefficient results and lead to common misconceptions?

Acute illness, pregnancy, and certain medications can temporarily shift cholesterol levels and the ratio without representing a stable change in cardiovascular risk. A common misconception is that the coefficient replaces a full lipid panel; it simplifies a complex system and is best used as a snapshot alongside LDL, total cholesterol, HDL, and personal risk factors. Hormonal changes also matter - men and postmenopausal women often have higher ratios as HDL declines.
