The short answer
Measures low-level inflammation in blood vessels — a key marker for heart attack and stroke risk, measured from a standard blood draw. At TestWell it costs $34.99 plus a $6 lab processing fee, needs no fasting, and results post in 2–4 business days. Physician-authorized with no doctor's visit or insurance needed; draw at Quest or Labcorp.

High-sensitivity C-Reactive Protein (hs-CRP) measures very low levels of CRP in your blood, which is a marker for inflammation in blood vessel walls. Elevated hs-CRP is associated with increased risk of heart attack and stroke, even in people with normal cholesterol. It's often ordered alongside a lipid panel for a more complete cardiovascular risk assessment.
High-sensitivity CRP measures low-grade inflammation in the body. Strongly associated with cardiovascular event risk independent of cholesterol.
Anyone over 40 doing a heart-health workup, people with a family history of cardiovascular disease, anyone monitoring chronic inflammation, athletes tracking recovery markers.

Your Heart & Body Inflammation Test (hs-CRP) 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 2–4 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. Already have results? Analyze them with your AI assistant against our physician-reviewed ranges.
No fasting required. Avoid vigorous exercise for 24 hours before the test.
What can throw off this result
Physician-reviewed “Before your test” pages — what each factor does, for how long, and what to do about it.
A Heart & Body Inflammation Test (hs-CRP) costs $34.99 at TestWell — $40.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Ordered directly from the labs' own consumer sites, the same test lists at $65.00 at Quest Health and $69.00 at Labcorp OnDemand (list prices checked Sep 12, 2026). Hospital outpatient labs typically bill around $100.00 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. Full cost breakdown →

High-sensitivity C-Reactive Protein measures low-grade systemic inflammation that standard CRP tests miss. It's particularly useful for assessing cardiovascular risk per the AHA/CDC framework: under 1 mg/L is low risk, 1-3 mg/L is average, above 3 mg/L is elevated.
Same molecule, different sensitivity. Standard CRP detects acute infections and major inflammation (typically above 10 mg/L). hs-CRP can measure the much lower levels (under 5 mg/L) associated with chronic vascular inflammation that drives heart disease.
Recent infections, injuries, intense workouts, surgery, dental procedures, or active autoimmune flares can spike hs-CRP for 1-2 weeks. Repeat the test 2-3 weeks after you've recovered for an accurate cardiovascular baseline.
On TestWell, hs-CRP is $34.99. Quest Direct lists the same test at $65, walk-in hospital labs typically bill $80-100 without insurance. Same CLIA-certified labs, same biomarker — TestWell just removes the markup.
The CPT code for high-sensitivity CRP is 86141. Standard (non-high-sensitivity) CRP is billed as 86140 — make sure your order specifies hs-CRP if you're using it for cardiovascular risk.
No fasting required. But because hs-CRP is often paired with a lipid panel or ApoB (which do benefit from fasting), most people fast anyway to bundle the draw.
Yes. Pair with a Lipid Panel, ApoB, and Lp(a) for a complete cardiovascular risk picture. The Heart Health Panel bundles all four at a discount vs ordering individually.
hs-CRP itself needs a standard blood draw, so there is no reliable at-home kit for it. TestWell is the closest equivalent: you order online from home, walk into any Quest or Labcorp patient service center when it suits you — no appointment or doctor's visit needed — and results post to your TestWell account in 2–4 business days. Many people order hs-CRP with ESR or a lipid panel from the same draw for a fuller picture of heart and body inflammation.
Ordered directly, a Heart & Body Inflammation Test (hs-CRP) lists at $65.00 at Quest Health (Quest Diagnostics' own site) and $69.00 at Labcorp OnDemand (prices checked September 2026). TestWell orders the same test at the same Quest or Labcorp patient service centers for $34.99 — $40.99 all-in with the $6 per-order lab processing fee — paid out of pocket at checkout with no insurance, doctor's visit or draw fee; HSA and FSA cards are accepted.
Heart & Body Inflammation Test (hs-CRP) results are typically ready in 2–4 business days after your draw at Quest or Labcorp. TestWell emails you the moment they post, and your results dashboard shows each marker against its reference range with a plain-English explanation.
Exercise, recent illness, smoking and nicotine and sleep deprivation can change a Heart & Body Inflammation Test (hs-CRP) result without anything being wrong. Exercise can raise hs-CRP — rest 48 hours before an inflammation marker. Recent illness can raise hs-CRP — wait 2 weeks (hs-CRP needs a well baseline). Smoking and nicotine can raise hs-CRP — do not attribute a mildly high CRP to another cause without considering smoking. Sleep deprivation can raise hs-CRP — recheck a mildly high CRP after normal sleep before acting on it. Each factor is covered on our physician-reviewed "Before your test" pages; when one applies, the fix is usually to remove it and retest.
Order the Heart & Body Inflammation Test (hs-CRP) online from TestWell for $34.99 (plus a $6 per-order lab processing fee) — no doctor's visit, referral or insurance needed. A licensed physician authorizes the order, then you walk into any Quest or Labcorp patient service center near you for the draw (the lab locator on our site lists the closest ones by ZIP code), and results arrive in 2–4 business days.
The Heart & Body Inflammation Test (hs-CRP) is Quest Diagnostics test code 10124, Labcorp test number 120766 ("C-Reactive Protein, Cardiac"), BioReference code 3320-9 ("C-Reactive Protein (hs-CRP), High Sensitivity") (CPT 86141).
