The difference between crp and pcr

the principle, application and operation are different.

1. The principle is different: CRP, called C- reactive protein, is an acute phase reaction protein, which is synthesized by liver cells. By measuring the CRP concentration, we can roughly infer the acute inflammatory infection. PCR, the full name of which is polymerase chain reaction, is a molecular biology technology, which replicates specific DNA sequences in vitro by controlling temperature and adding raw materials.

2. Different applications: CRP is often used in the auxiliary diagnosis of infectious diseases, such as bacterial infection and virus infection. PCR technology is widely used in genetic disease detection, gene cloning, disease diagnosis and other fields.

3. Different operation: CRP detection is simple, just put the specimen in the equipment, and the machine will automatically complete the detection process. And PCR needs to go through complicated operation steps, including denaturation, annealing, extension and other processes, and it needs a certain technical level to complete.
