High hs-CRP: what it means for heart risk, causes and what to check next
Short answer
High-sensitivity CRP grades low-level inflammation for cardiovascular risk: below 1 mg/L is low risk, 1–3 average, above 3 high. Above 10 mg/L the test is no longer reading vascular risk but an acute infection, injury or inflammatory flare, and it is repeated in 2–3 weeks. A persistently raised hs-CRP (2 mg/L or more) is a risk enhancer in the 2018 AHA/ACC cholesterol guideline — it tips borderline statin decisions and in the JUPITER trial identified people with normal LDL who benefited from one — but it is a marker to act around, mostly by treating the metabolic and lifestyle causes beneath it.

What is the normal range for hs-CRP?
- age 18+: 0 – 3 mg/L
Above 3 mg/L suggests higher cardiovascular risk; above 10 mg/L often reflects acute infection or inflammation rather than chronic risk.

What are the common causes of high hs-CRP?
- Visceral (abdominal) fat, metabolic syndrome, prediabetes and type 2 diabetes — fat tissue secretes the interleukin-6 that drives CRP
- Smoking, physical inactivity and a diet high in refined carbohydrate and processed food
- Obstructive sleep apnea and short or disrupted sleep
- Periodontal (gum) disease and other chronic low-grade infections
- Chronic inflammatory conditions — rheumatoid arthritis, psoriasis, inflammatory bowel disease, lupus — and chronic kidney disease
- Estrogen-containing contraceptives and oral hormone therapy (raise hs-CRP; transdermal estrogen does not), depression and chronic stress
- Any acute infection, injury, dental work, vaccination or hard exercise in the previous two weeks — values above 10 mg/L are usually this and are repeated
- Age — hs-CRP drifts up across adulthood; women run slightly higher than men
What symptoms go with high hs-CRP?
- None — hs-CRP is a risk marker, not a symptom-producing condition
- The metabolic company it keeps: a large waist, high triglycerides, low HDL, raised glucose and blood pressure
- Snoring with daytime sleepiness (sleep apnea), bleeding gums (periodontitis), or joint and skin symptoms of an inflammatory disease
What do clinicians usually check next?
- Above 10 mg/L: repeat in 2–3 weeks when well — the first value was acute inflammation, not vascular risk
- Two measurements at least two weeks apart, averaged, before using the result in a risk decision (hs-CRP varies about as much as cholesterol between draws)
- A lipid panel with ApoB and a one-time lipoprotein(a), hemoglobin A1c and blood pressure — the risk factors hs-CRP amplifies
- A 10-year ASCVD risk estimate; at 5–20% risk an hs-CRP of 2 or more is a risk enhancer that favors statin therapy, and a coronary calcium score settles the uncertain middle
- Treat the sources: weight loss (especially visceral fat), exercise, stopping smoking, a dental check-up, sleep apnea evaluation when snoring and sleepiness are present; statins lower hs-CRP 15–30% independent of LDL
- A persistently high hs-CRP with joint, gut or skin symptoms is a standard-inflammation question — ESR, CBC and the relevant specialist work-up
Follow-up tests available at TestWell: CBC with Differential Test ($17.99), Body Inflammation Test (ESR) ($18.99), Lipid Panel ($19.99), Hemoglobin A1c Test ($18.99), C-Reactive Protein Test (CRP) ($26.99), Calcium Test ($16.99).
For cardiovascular risk assessment, the AHA/CDC statement recommends averaging two hs-CRP measurements taken at least 2 weeks apart, and skipping the test during an infection, injury, or flare — any acute inflammation pushes CRP up for days and would hide your baseline. Retest once you've been well for at least two weeks.

Common questions
What is a high hs-CRP?
Above 3 mg/L is the high cardiovascular-risk band (below 1 low, 1–3 average), and 2 mg/L or more counts as a risk enhancer in the 2018 AHA/ACC guideline. Above 10 mg/L the test is reading an acute infection, injury or flare rather than vascular risk and is repeated in 2–3 weeks.
What causes high hs-CRP?
Most often abdominal fat and insulin resistance, smoking, inactivity, poor sleep or sleep apnea, gum disease and chronic inflammatory conditions. Oral estrogens raise it. Any recent infection, injury, dental work or hard workout pushes it above 10 for a couple of weeks, which is why a high result is always repeated before anything is decided.
How do I lower hs-CRP?
Treat its sources: losing visceral fat, regular exercise, stopping smoking, treating sleep apnea and gum disease, and a diet built on unsaturated fats, fiber and less refined carbohydrate each lower it. Statins lower hs-CRP 15–30% independent of their cholesterol effect, which is part of why they are favored when hs-CRP is raised alongside other risk.
Is hs-CRP the same as CRP?
Same protein, different scale. Standard CRP measures whole mg/L from about 3–10 upward for infection and inflammatory disease; high-sensitivity CRP resolves 0.1–10 mg/L to grade long-term cardiovascular risk. A standard CRP cannot answer the heart question, and an hs-CRP above 10 should be read as a standard CRP and repeated.
