You can check your liver function in advance. If your liver function is normal, you can apply for a health certificate. If your liver function is abnormal, you can consider returning to normal after treatment! Staying up late and drinking too much may lead to abnormal liver function. Pay attention to these before checking! The above are suggestions on whether I have hepatitis B but can get a health certificate in Dongpu People's Hospital normally. I hope it helps you, and I wish you health!
