Utilization value of infectious index ''CRP, PCT''

Infectious diseases are common and frequently-occurring diseases in the clinic. If not diagnosed early and treated in time, the progression of the disease can lead to sepsis, multiple organ dysfunction syndrome (MODS), and even life-threatening. The early clinical signs of infection are often atypical. How to select highly sensitive and specific laboratory diagnostic markers to assist clinicians in early diagnosis is of great significance to make a rapid and accurate diagnosis of the patient's condition.

In recent years, with the rapid development of the in vitro diagnostic industry, more rapid, simple and accurate serological testing has played an increasingly important role in the diagnosis of early infectious diseases. Routine blood, C-reactive protein (CRP) and procalcitonin (PCT) are traditional detection indicators, which are widely used in the diagnosis and prognosis evaluation of clinical infectious diseases.
