Does the health code still show nucleic acid after unbinding?

After the health password was released, no nucleic acid was made, and it was still displayed. After the health code is unbound, if you reapply, the previous records will still be available. Now is the era of big data, and the health code is specially set for the COVID-19 epidemic, based on personal identity information. So as long as you apply for the same ID number, even if the mobile phone number is different, the health code must be the previous information, and the itinerary, vaccination and nucleic acid detection date will be recorded.
