Inflammation Monitoring	IL-6	IL-6 is mainly produced by macrophages, T cells, B cells and other cells. It can regulate the growth and differentiation of various cells, regulate immune response, acute phase response and hematopoietic function, and play an important role in the body's anti-infection immune response. IL-6 is significantly altered in a variety of diseases. The dysregulation of IL-6 expression can cause many diseases, and its clinical manifestations are mainly increased IL-6 levels during the onset. The elevated level of IL-6 is closely related to the active stage of the disease, the development and change of the tumor, the degree of rejection and the treatment effect. Therefore, the detection of the level of IL-6 in the patient's body fluid can reflect the change of the patient's condition. This product can be used to evaluate infections, tissue damage and inflammatory diseases, and can also be used as an aid in the identification of cardiovascular disease risk.
	PCT	Elevated PCT levels are seen in bacterial sepsis, especially severe sepsis and septic shock. PCT can be used as a prognostic indicator of sepsis, as well as for acute severe pancreatitis and its major complications On target. PCT can be used as anti-respiratory agent in patients with community-acquired respiratory tract infections and air-conditioned pneumonia The index of biogenic selection and efficacy judgment.
	CRP	Routine CRP assays include qualitative, semi-quantitative, and quantitative assays and can be used to evaluate infections, tissue damage, and inflammatory diseases. For routine CRP assays, reference values are generally considered to be clinically higher than 10 mg/L. CRP levels in the blood of healthy people are less than 5 mg/L, while under various conditions, CRP values reach about 20 to 500 mg/L within 4 to 8 hours of acute inflammation. Conventional CRP is more sensitive and reliable than erythrocyte sedimentation rate (ESR) and white blood cell count as an assessment of acute inflammation.
	SAA	The full name of SAA is serum amyloid A, which is an acute phase reaction protein secreted into serum after being produced by hepatocytes. White, when the body is infected or injured, it can ly increase by about 1000 times within 4-6 hours. After the body's antigens are cleared, it can quickly return to normal levels, so SAA can be used as a sensitive indicator to reflect the body's infection and inflammation recovery. Compared with the current widely used CRP in clinical practice, the difference of SAA is that its elevation is commonly seen in viral, mycoplasma, and bacterial infections, and its sensitivity is higher than that of C-reactive protein. Elevated C-reactive protein is more common in bacterial infections, but only mildly elevated in pathogens such as viruses and mycoplasma or not elevated. While SAA is a sensitive indicator for diagnosing viral and bacterial infections, SAA and C. Compared with reactive protein, the main advantage is that it rises earlier and the rise range is larger, and the sensitivity is higher. Especially in the early stage of acute bacterial infection, the advantage of detecting SAA is more obvious, and SAA is significantly increased in viral infections, but C-reactive protein does not increase. Therefore, SAA can be used as a sensitive indicator for the diagnosis of viral infection.
