High serum amyloid A indicates that an individual may have an infectious disease.
Serum amyloid A is similar to C-reactive protein and is a more sensitive indicator of early inflammation. A high test result indicates an infection, but it is not certain that it is a bacterial infection, as viral infections and mycoplasma infections can also result in an elevated test result, and further definitive testing should be done.
Serum amyloid A is more sensitive than C-reactive protein and is elevated when there is inflammation. If the test result is high and there are no uncomfortable symptoms, no special treatment is needed and follow-up is sufficient. If there are symptoms such as sneezing, runny nose and cough, fever, etc., you can further do blood routine and chest CT, sputum culture and other tests to determine whether it is bacterial, viral, mycoplasma infection before choosing drug treatment.
In addition to the above factors, malignant tumors, rheumatoid arthritis, as well as the rejection reaction after organ transplantation can also appear high serum amyloid A. At this time, the patient should be guided by the doctor to do the next examination, to clarify the cause of the disease, and then actively treat.
