Blood tests known as 'inflammatory markers' can detect inflammation in the body, caused by many diseases including infections, auto-immune conditions and cancers. The tests don't identify what's causing the inflammation: it might be as simple as a viral infection, or as serious as cancer.
High levels of CRP may mean you have a serious health condition that causes inflammation. Inflammation is your body's way of protecting your tissues and helping them heal from an injury, infection, or other disease. Inflammation can be acute (sudden) and temporary. This type of inflammation is usually helpful.
The C-reactive protein (CRP) test is a blood test that checks for inflammation in your body. CRP is a protein that is made in your liver and released into your bloodstream. Levels of CRP start to increase very soon after any inflammation or infection affects your body.
Having a raised inflammatory marker doesn't always mean you have a disease, they can also be raised in people who are overweight; ESR is also affected by age, gender, smoking and anaemia. It's also important to know that a normal inflammatory marker test result does not exclude illness.
Based on visual observation, the ancients characterised inflammation by five cardinal signs, namely redness (rubor), swelling (tumour), heat (calor; only applicable to the body' extremities), pain (dolor) and loss of function (functio laesa).
5 signs of inflammation
body pain. constant fatigue and insomnia. depression, anxiety, and other mood disorders. gastrointestinal issues, like constipation, diarrhea, and acid reflux.
Studies of specific cancers in symptomatic primary care patients have reported an association between raised inflammatory markers for bladder and kidney cancers, Hodgkin and non-Hodgkin lymphomas, plus myeloma, albeit with very low positive predictive values (PPVs) for a raised inflammatory marker result.
Third, CRP is only one of the inflammatory markers, and a recent study has reported that genetically predicted circulating concentrations of several inflammatory-related cytokines were associated with the risk of breast, endometrial, lung, ovarian, and prostate cancer [39].
Causes of an inflammation
Pathogens (germs) like bacteria, viruses or fungi. External injuries like scrapes or damage through foreign objects (for example a thorn in your finger) Effects of chemicals or radiation.
Most blood tests aren't used on their own to diagnose cancer. But they can provide clues that may lead your health care team to make the diagnosis. For most types of cancer, a procedure to remove a sample of cells for testing is often needed to be sure.
Aside from leukemia, most cancers cannot be detected in routine blood work, such as a CBC test. However, specific blood tests are designed to identify tumor markers, which are chemicals and proteins that may be found in the blood in higher quantities than normal when cancer is present.
Blood Tests
A low level of red blood cells, white blood cells or platelets may indicate that the lymphoma is present in the bone marrow and/or blood.
What are the signs of inflammation? The four cardinal signs of inflammation are redness (Latin rubor), heat (calor), swelling (tumor), and pain (dolor). Redness is caused by the dilation of small blood vessels in the area of injury.
Chronic inflammation can contribute to an overproduction of inflammatory cytokines. As the body gets flooded with these molecules during chronic inflammation, the cytokines actually begin to attack healthy joint and muscle tissue, resulting in pain, swelling, redness, and stiffness.
In summary, preliminary evidence suggests that acute and chronic stress is associated with increased inflammatory activity and enhanced attentional processing of negative information. Both are predictive of negative mood and depression symptoms that, in turn, increase inflammatory and cognitive stress reactivity.
Five cardinal signs characterize this response: pain, heat, redness, swelling, and loss of function.
Some of the most common signs of chronic inflammation include: Body discomfort, including joint stiffness, tendonitis and muscle pain. Sleep disorders like insomnia, sleep apnea and persistent fatigue. Weight gain or unexplained weight loss.
Values above 2.0 mg/L may mean an increased risk of heart attacks or risk of a repeat heart attack. Hs-CRP level is only one risk factor for coronary artery disease. Having a high hs-CRP level doesn't always mean a higher risk of developing heart disease. Other tests results can help determine the risk.
A few biologic compounds meet the criteria for an ideal tumor marker; C-reactive protein (CRP) is one [3]. It is a non-specific acute phase reactant which reflects tissue damage.
