This invention relates to a method for identifying 28 kinds of common pathogens of clinical bacteremias, which belongs to the molecular biology and biochemistry field of biotechnology, relates to a suspension chip technology for identifying common pathogens of clinical bacteremias, applies to culture identification for clinically separating the bacterial strain and provides guide for clinical bacteremias patient to accurately and reasonably treating by using antibacterial agents, which crosslinks 30 types of specific probes against the 28 kinds of common pathogens on 30 kinds of different fluorescent microspheres to be reacted with the being tested specimens then to be reacted with the report molecules labeled by fluorescent elements to test the specific 23SrDNA of them on a fluorescent test device. The method comprises advantages of high susceptibility, great specificity, good bacterial strain efficient and short detecting time.
