What diseases can be detected by whole blood c-protein reaction

Whole blood C-reactive protein testing is mainly used to screen for inflammation, infection, and cardiovascular disease risk. The increase of this index may indicate such pathological conditions as bacterial infection, rheumatic immune disease, tissue damage or atherosclerosis.

C-reactive protein is synthesized by the liver and its level rapidly increases when the body experiences an inflammatory response. Bacterial infections such as pneumonia, urinary tract infections, appendicitis, and other acute infections often lead to significant increases in values, while viral infections usually only cause mild increases. Patients with autoimmune diseases such as rheumatoid arthritis and systemic lupus erythematosus may experience sustained moderate elevation. Tissue damage after trauma, surgery, or myocardial infarction can also cause an increase in this indicator. For the cardiovascular system, the detection of high-sensitivity C-reactive protein can reflect the inflammatory activity of atherosclerotic plaque, and the probability of myocardial infarction and cerebral infarction will increase if the value is high for a long time.

The baseline level of C-reactive protein in patients with some chronic diseases such as obesity and diabetes may be higher than that in normal people. Malignant tumors, especially lymphoma patients, may experience abnormal elevation. A small number of healthy individuals may also exhibit physiological abnormalities due to genetic factors or smoking habits. The test results need to be combined with clinical symptoms and other examinations to make a comprehensive judgment. Abnormal single indicators cannot diagnose the disease.

It is recommended to avoid vigorous exercise and alcohol consumption before testing. After acute infection is cured, re examination should be conducted to confirm the decline of indicators. Long term high risk patients need to be regularly monitored for cardiovascular and cerebrovascular risks, and if necessary, undergo in-depth examinations such as carotid ultrasound and coronary CT. Maintaining a low-fat diet and regular exercise on a daily basis can help control inflammation levels.
