Can you find out by taking someone else's blood as a health certificate?

Of course. You can't ask someone to draw blood for you when you apply for a health certificate, because there are names and photos when you draw blood, and this information will be verified. This situation is not allowed and is a serious violation of the Food Safety Law. To apply for a health certificate, you must go to a designated hospital for examination and testing. If you apply for a health certificate instead of others, you will bear legal responsibility. Getting a health certificate is an effective means, which is beneficial to the health of individuals and others. Therefore, you must abide by the rules and national laws and regulations, actively handle and reasonably handle the health certificate.
