Polymerase Chain Reaction (PCR) is the most commonly used method for nucleic acid testing. The general principle of PCR detection is a process of in vitro replication of daughter strand Deoxyribo Nucleic Acid (DNA) complementary to parent strand DNA with the parent strand DNA as a template and a specific primer as an extension starting point under the catalysis of DNA polymerase.

Therefore, the transfer of the extraction plate, the amplification plate, and the cover body in the same path, as well as the combination of the amplification plate and the cover body are realized through the to-be-tested object processing apparatus, which has the characteristic of simple structure and reduces the volume of the to-be-tested object processing apparatus.
