Principles of digital PCR and its applications in current obstetrical and gynecological diseases

Digital PCR (dPCR) is a revolutionary technique to precisely quantify nucleic acids. For its high sensitivity and specificity, this technique has been widely replicated worldwide. To verify its applicability, we reviewed all the related articles in PubMed database published before May 10, 2019. Original articles and reviews on the topics were selected. Entered key words included "digital PCR/dPCR", "advantage", "combined use", "microfluidic chip", "gynecological cancer/tumor". We found that dPCR has shown great potential in clinical operations, like tumor liquid biopsy, non-invasive prenatal diagnosis, microorganism detection, and next-generation sequencing library quality-control.
