Inflammation is a buzzword you hear everywhere in health circles. Acute inflammation is good—it's how your body heals a cut or fights a throat infection. But chronic, systemic inflammation is bad. It's a low-grade fire burning constantly inside your body, and it is the root cause of heart disease, diabetes, arthritis, and even Alzheimer's.
\n\nThe Smoke Detector: C-Reactive Protein
\n\nWhen there is inflammation anywhere in your body, your liver produces a substance called C-Reactive Protein (CRP) and releases it into your bloodstream.
\n\nA standard CRP test is a broad marker. If it is extremely high, it tells the doctor there is an active fire—perhaps a severe bacterial infection, a flare-up of an autoimmune disease, or severe tissue injury. It doesn't tell them exactly where the fire is, but it tells them to look for it.
\n\nThe hs-CRP Test for Heart Health
\n\nThere is a more sensitive version of this test called high-sensitivity CRP (hs-CRP). This test can detect very tiny elevations in CRP. Cardiologists use this test to evaluate your risk of a heart attack.
\n\nEven if your cholesterol is normal, a high hs-CRP means your blood vessels are inflamed. This inflammation makes it much more likely that plaque will rupture, causing a clot and a heart attack. Knowing your hs-CRP level helps doctors aggressively target inflammation with lifestyle changes and medication. Add it to your next cardiac profile.
