Is the biological sequencer hard?

Biological sequencer is difficult. Recently, I saw that there are nurse certificates and PCR certificates, which are for people who want to do nucleic acid testing and need to study medicine or biology. Some people apply for PCR certificates. Obtaining PCR certificate requires training, mainly for the laboratory staff of medical institutions who have carried out or intend to carry out clinical gene amplification verification. Personnel engaged in molecular biology diagnosis technology or other relevant personnel can also participate. Nucleic acid testers also need to bear great hardships and pressures. At present, nucleic acid samples are delivered around 8 pm, and the laboratory needs to classify and input sample information one by one. The whole process takes 2 hours, and the real detection time is only 8 pm to 4 am, ***6 hours. It's actually quite hard.
