In March this year, I took a health certificate examination at Shanghai International Travel Health Care Center. At that time, hepatitis B was detected and the result was HBsAg 0.00. Why didn't it appear on the health certificate?
At present, the state stipulates that compulsory detection of hepatitis B virus surface antigen is not allowed, mainly to protect the privacy of subjects.
If you did pay for the HBsAg test, and you have relevant invoices and receipts, you can complain to him, because the final health certificate you got didn't have the test results of this item.
