The short answer
Measures oxidized LDL cholesterol — the form most damaging to arteries and most predictive of plaque buildup, measured from a standard blood draw. At TestWell it costs $42.99 plus a $6 lab fee, requires an 8–12 hour fast, and results post in 5–7 business days. Physician-authorized with no doctor's visit or insurance needed; draw at Quest or Labcorp.

Oxidized LDL is a modified form of LDL cholesterol that has been damaged by free radicals. Unlike standard LDL, oxidized LDL is actively taken up by immune cells in artery walls, triggering the inflammatory cascade that leads to atherosclerotic plaque. It is considered a more direct measure of cardiovascular risk than total LDL alone. Elevated oxidized LDL is associated with metabolic syndrome, diabetes, smoking, and diets high in processed foods.
Cardiovascular biomarkers identify hidden risk for heart attack and stroke years before symptoms appear, allowing for earlier intervention with diet, exercise, or medication.
Adults 35+ for routine cardio screening, anyone with family history of premature heart disease, and patients tracking response to statins, lifestyle changes, or other cardiovascular therapy.

1 biomarker tested
Your Oxidized LDL results will include values for each of the 1 biomarker tested, along with reference ranges. Results are reviewed by a licensed physician before being released to your secure portal.
If any values fall outside the normal range, your report will include guidance on what that may mean and recommended next steps. You'll receive an email notification when your results are ready, typically within 5–7 business days.
Typical reference range layout
Lab reports show where your value sits relative to established reference intervals—your physician interprets this in context for you.
Fasting for 12 hours recommended.
A Oxidized LDL test costs $42.99 at TestWell — $48.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Hospital outpatient labs typically bill around $200.00 self-pay for the same test, and often more. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible.
