Rapid Ultrasensitive C Reactive Protein is usually used as an indicator of acute inflammation in the clinic, and elevated rapid ultrasensitive c-reactive protein can occur when inflammation is present in the body. Common factors leading to its elevation include infectious factors, malignant tumors, and tissue cell necrosis. 1. Infectious factors: the most common are bacterial infections, such as staphylococcus, streptococcus pneumoniae, dysentery bacillus, etc. Rapid ultra-sensitive c-reactive protein is often moderately or significantly elevated in bacterial infections. In addition, it can also be seen in some viral infections, such as influenza virus, can also show a mild elevation. 2. Malignant tumors: malignant tumors often show moderate or significant elevation of fast ultra-sensitive c-reactive protein. 3. Tissue cell necrosis: It is common in severe pancreatitis, burns, post-surgery, etc. When there is tissue cell necrosis, rapid ultra-sensitive c-reactive protein can also be elevated. In addition to the above factors, connective tissue disease, vasculitis, coronary artery disease and other diseases can also lead to rapid ultrasensitive c-reactive protein elevation. If the patient’s test shows elevation, he/she can consult a medical professional and should take the next step in the examination and treatment under the guidance of the doctor.
