Does the welfare body of Wen's group company check half of hepatitis B?

I won't check half of hepatitis B. According to national regulations, companies are not allowed to check hepatitis B in two halves to prevent hepatitis B personnel from being treated differently. But it will check liver function. If the liver function is abnormal, it is necessary to further improve the relevant tests and clarify the causes of abnormal liver function. Hepatitis B is an acute and chronic liver disease caused by hepatitis B virus.
