SAA indicator 59 μg/mL does not necessarily require the use of antibiotics, SAA is an indicator of inflammation, but more closely related to viral infections, can not be based on this to determine that the bacterial infection, need to refer to other indicators of the examination, the use of antibiotics need to be in the regular hospital under the guidance of a professional doctor in order to avoid abuse. SAA is human serum amyloid, an acute time-phase reaction protein. it is a sensitive parameter, which is significantly elevated in both bacterial and viral infections, and the short half-life of SAA is only 50 minutes, which can reflect the severity of the disease in time. However, SAA level alone is not enough to determine the need for antibiotics, but also need to be combined with other test indicators, such as blood white blood cell count, CRP (C-reactive protein) and so on. Generally speaking, an elevated SAA with normal CRP is considered a viral infection, while a bacterial infection is considered a bacterial infection when both SAA and CRP are elevated, and only then antibiotics, such as penicillin, amoxicillin, and erythromycin, are administered. Whether and how to use drugs need to be under the guidance of a professional doctor, do not use drugs on your own.
