When you lose your ID card and do a nucleic acid test, you can provide the ID card number, or use other documents to prove your personal identity, such as health code, social security card, etc., which can prove your identity. This is a more important proof of personal identity and can replace the use of ID cards. For young children who do not have ID cards, they can bring their household registration book for nucleic acid testing, because the household registration book contains the child's ID number.

Precautions for nucleic acid testing are as follows:

1. Do not eat two hours before the nucleic acid test. To avoid affecting the test results, please do not smoke or smoke 30 minutes before sampling. Drinking alcohol and chewing gum;

2. During the nucleic acid testing process, actively cooperate with the requirements of the sampling personnel. During the examination, the head is slightly tilted back and the mouth is opened wide, which helps to expose the throat and complete the test quickly;

3. Leave the collection site immediately after collection and avoid spitting around the collection site. Vomit. You need to pay attention to hand hygiene before and after nucleic acid testing. You can use hand sanitizer or alcohol, disinfectant cotton pads, etc. to wipe your hands.
