Ultrasensitive C-reactive protein is synthesized by the liver as a non-specific marker that reflects the acute phase of systemic inflammatory response. Its serum levels are closely related to various infections, tissue damage and immune responses. A rise in the value of ultrasensitive C-reactive protein between 10-20 mg/L is a mild increase in ultrasensitive C-reactive protein, but not serious. It usually indicates an infection, commonly caused by viral infections, or minor bacterial infections causing inflammation, usually slightly elevated cases can be self-healing; if the value is too high more than 20mg/L, often the higher the value proves that the more serious inflammation, and even the emergence of brain infarction, myocardial infarction, etc., then usually can not be self-healing, need to go to the hospital for further examination in a timely manner for professional scientific treatment. 1, can be self-healing: for cases that can be self-healing The situation is common in seasonal colds caused by the influenza virus. The symptoms are mild, only mild nasal congestion, runny nose, low fever and other symptoms, the systemic inflammatory response is light, no general weakness, muscle aches and other symptoms, does not affect the daily work life. Other tests are basically within the normal range, such as blood routine, etc. Generally 7-10 can achieve the effect of self-healing; 2, not self-healing: for the case of not self-healing, it is common in more serious infections, in addition to myocardial infarction, burns and malignant tumors can also lead to elevated ultrasensitive C-reactive protein. These diseases are usually accompanied by more obvious changes in test results, such as white blood cells greater than 10xl0^9/L, elevated cardiac enzymes, abnormal electrocardiograms, etc. The patient’s general discomfort is more serious, which can be manifested as fever, difficulty in breathing, redness or pain at the site of the lesion, etc. This condition cannot be self-healed. Patients with heart attack need timely surgery to dilate coronary arteries; patients with burns need to use antibacterial drugs to prevent and treat infections; patients with malignant tumors need surgery and drug therapy or interventional treatment. For patients with high ultrasensitive C-reactive protein, it is recommended to improve the blood routine, chest CT, ECG and other examinations in time for comprehensive analysis and diagnosis by the doctor, and treatment according to the diagnosis, it is not recommended to wait for the disease to heal on its own, which may delay the disease, increase the difficulty of treatment, and may even affect the prognosis.
