Blood testing of voluntary blood donation is carried out in blood centers or blood stations, mainly to detect various hepatitis and blood-borne diseases, such as hepatitis B, hepatitis C, syphilis and AIDS. Other tests include transaminase and blood type. I hope I can help you.
PS: It is not recommended to obtain your health information by donating blood. If you suspect that you are sick, it is recommended to go to a professional medical institution for examination, because the blood test information of the blood station will not tell you in detail according to national laws and regulations, but will only tell you whether it is qualified or unqualified.
