You test for systemic inflammation primarily through blood tests that measure inflammatory markers like C-reactive protein (CRP), especially high-sensitivity CRP (hsCRP), and the Erythrocyte Sedimentation Rate (ESR), which show general inflammation but not its location. Other markers include fibrinogen, ferritin, and cytokines like IL-6, while imaging like ultrasounds might be used for localized issues, all to help diagnose underlying causes like infections, autoimmune diseases, or heart risks.
By measuring the levels of c-reactive protein in your blood, a CRP test can tell your health care provider how much inflammation you have in your body. High CRP levels may mean you have an acute or chronic health condition, such as: Infections from bacteria or viruses.
CRP (C-reactive protein) in pregnancy reflects inflammation, with levels naturally higher than in non-pregnant women but varying; it's a key marker for diagnosing infections (as it doesn't cross the placenta), but elevated levels also signal low-grade inflammation linked to risks like preterm birth, fetal growth restriction, preeclampsia, and potential long-term child health issues, with higher levels seen in obesity and smoking. Doctors use specific pregnancy reference ranges, as general norms don't apply well, and track trends rather than single high values for better diagnosis.
The two blood tests that are inexpensive and good markers of systemic inflammation include high-sensitivity C-reactive protein (hsCRP) and fibrinogen.
Clinically, acute inflammation is characterized by five cardinal signs: rubor (redness), calor (heat), tumor (swelling), dolor (pain), and functio laesa (loss of function).
There are several classic signs of systemic inflammation. They include a fever, headache, fatigue, alterations in CNS, and body aches.
To reduce body inflammation and support natural detoxification, focus on an anti-inflammatory diet rich in fruits, vegetables, fatty fish, and whole grains, while limiting processed foods, sugar, and refined oils; incorporate fiber for gut health, stay hydrated with tea and water, manage stress, get adequate sleep, and consider exercise and supplements like omega-3s or turmeric, say experts from Cleveland Clinic, Healthline, Johns Hopkins Medicine, and Harvard Health.
Common causes include:
Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are blood tests that can be used to check the levels of inflammation in your body.
If your CRP (C-reactive protein) is high, a doctor will investigate the underlying cause with further tests (like blood cultures, imaging, or autoimmune markers) to find the source of inflammation, which could be infection, autoimmune disease, or injury. Treatment focuses on the root problem with medications (antibiotics, anti-inflammatories, statins) or lifestyle changes (diet, exercise, stress management) and involves monitoring CRP levels to track improvement, as a high CRP signals inflammation but not a specific disease.
CRP rises within hours of onset of an infection or inflammatory condition and returns to normal within three to seven days if the acute process is resolved. ESR, on the other hand, increases in a slower manner and remains elevated for a longer period of time.
Angiotensin receptor blockers (ARBs) (valsartan, irbesartan, olmesartan, telmisartan) markedly reduce serum levels of CRP. The findings with other ARBs (losartan and candesartan) were inconsistent. Antidiabetic agents (rosiglitazone and pioglitazone) reduce CRP levels, while insulin is ineffective.
Possible causes of high blood protein include:
In clinical practice, serum IL-6 levels are usually applied to inflammatory or infectious diseases. Increased IL-6 levels have been reported in patients diagnosed with breast, cervical, esophageal, head and neck, ovarian, pancreatic, prostate, and renal cancers.
This blood test finds out if you have a systemic infection. This is an infection that affects your whole body, not just one part. A sample of blood is studied in a lab to check for bacteria or for a type of fungus called yeast.
The erythrocyte sedimentation rate (sedimentation rate, sed rate, ESR) serves as a routine hematology test used to detect and monitor increased inflammatory activity in response to conditions such as autoimmune disorders, infections, or tumors.
Range values vary depending on the lab doing the test. A high hs-CRP test result is a sign of inflammation. It may be due to serious infection, injury or chronic disease. Your healthcare professional may recommend other tests to determine the cause.

This can include infections, auto-immune conditions and cancers. The three most commonly used inflammatory markers are called C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and plasma viscosity (PV).
The five cardinal signs of inflammation, first described by the ancients and later expanded, are redness (rubor), heat (calor), swelling (tumor), pain (dolor), and loss of function (functio laesa), resulting from the body's protective response to injury or infection, characterized by increased blood flow, fluid buildup, and chemical signals affecting nerve endings.
