Background

Healthy human blood is free of bacteria, and once blood is infected with bacteria, various discomforts may occur, bacteremia, septicemia, sepsis and the like occur, and serious patients may die. To determine whether bacteria are infected in the blood, blood culture tests are performed. Clinical data show that the mortality rate of bacteremia and sepsis is as high as 30-50%, and 10 patients out of 100 inpatients need to be tested.

For patients with severe sepsis, early diagnosis and rational treatment have a great influence on improving the therapeutic effect. The longer the delay in starting treatment, the greater the chance of patient survival will be, and if the patient receives antibiotic treatment within the first hour of diagnosis, the chance of survival will be close to 80%, and thereafter decrease by 7.6% every other hour. However, if a patient initially receives inappropriate antibiotic therapy, the chances of survival may be reduced by a factor of five. Pathogenic microorganism detection is carried out at the first time, and the use of antibiotics is reasonably adjusted according to the identification result of pathogens. Thus, a quick, reliable diagnosis will help the clinician make clinical decisions to ensure that the treatment is proceeding smoothly.
