In the Xiangyang Central Blood Station, how is the blood tested after donating? Are the tests for hepatitis B, HIV, syphilis, etc. strict?

ELISA, enzyme-linked immunosorbent assay. It's part of the medical test and immune test. It's a more professional question. If it is a nucleic acid pilot unit of the Ministry of Health, there is also a nucleic acid laboratory that will further test the virus in the blood. At the molecular level, we will also become NAT. It is similar to the PCR in the hospital, but it is better and more intelligent than the hospital.
