| Abstract: |
| ［Abstract］ Polymerase chain reaction(PCR) is a molecular biology technique used to amplify certain fragments of deoxyribonucleic acid(DNA). It is a common and indispensable technique that has been used in many fields, especially in clinical laboratories. Droplet digital polymerase chain reaction(ddPCR) is a third-generation PCR, which is a biotechnology obtained by improving the conventional PCR method, and can be used to directly quantify and clonally amplify DNA.Droplet digital PCR is now widely used for low-abundance nucleic acid detection, which can be used for the diagnosis of infectious diseases. This paper introduces the development and principle of ddPCR detection means, summarizes its potential advantages in the clinical diagnosis of viral diseases, bacterial diseases and fungal diseases, and draws the conclusion that ddPCR is more sensitive and accurate and repeatable for the detection of low-abundance pathogens, and may be a better choice than quantitative PCR in future clinical applications. |
