Abstract: Digital PCR (dPCR) is the latest technique that has become commercially accessible for various
types of research. This method uses Taq polymerase in a standard polymerase chain reaction (PCR) to amplify
a target DNA fragment from a complex sample, like quantitative PCR (qPCR) and droplet digital PCR (dd-
PCR). ddPCR may facilitate microRNA (miRNA) measurement, particularly in liquid biopsy, because it has
been proven to be more effective and sensitive, and in this method, ddPCR can provide an unprecedented
chance for deoxyribonucleic acid (DNA) methylation research because of its capability to increase sensitivity
and precision over conventional PCR-based methods. qPCR has also been found to be a valuable standard technique
to measure both copy DNA (cDNA) and genomic DNA (gDNA) levels, although the finding data can be
significantly variable and non-reproducible without relevant validation and verification of both primers and
samples. The SYBR green quantitative real-time PCR (qPCR) method has been reported as an appropriate
technique for quantitative detection and species discrimination, and has been applied profitably in different experiments
to determine, quantify, and discriminate species. Although both TaqMan qRT-PCR and SYBR
green qRT-PCR are sensitive and rapid, the SYBR green qRT-PCR assay is easy and the TaqMan qRT-PCR
assay is specific but expensive due to the probe required. This review aimed to introduce dPCR, qPCR, SYBR
green PCR kit, and digital PCR, compare them, and also introduce their advantages in the detection of different
diseases.
