High ultrasensitive c-reactive protein may suggest infection, autoimmune disease, systemic lupus erythematosus, rheumatoid arthritis, trauma and so on. 1. Infections: Bacterial, viral, and parasitic infections may lead to high ultrasensitive c-reactive protein. 2. Autoimmune diseases, systemic lupus erythematosus, rheumatoid arthritis, and malignant tumors may also lead to elevated ultrasensitive c-reactive protein and a greater degree of elevation. 3. Trauma: Ultrasensitive C-reactive protein will rise significantly when there is trauma to organs in the body such as myocardial infarction and surgery leading to trauma outside the body. 4. Cardiovascular disease, neonatal infections: Ultrasensitive C-reactive protein is valuable in predicting the onset and progression of cardiovascular events and in the assessment of risk. In addition. Ultrasensitive C-reactive protein is also elevated in neonatal bacterial infections. Ultrasensitive C-reactive protein is only an auxiliary means of checking the blood, and the definitive diagnosis of many diseases needs to be judged in conjunction with other tests to clarify the cause of the disease and then treat it.
