It can also reduce the incidence of cancer.

The average life expectancy of blood donors was 70.1 years, while that of non-blood donors was 67.5 years. 2.6 years older.

5. Voluntary blood donors will receive a free physical examination. The blood of voluntary blood donors will undergo systematic testing (three times in total: rapid test, initial test, and re-test). There are eight inspection items in total, namely blood type, RH, hemoglobin, transaminase, hepatitis B, hepatitis C, syphilis, and AIDS. Only all qualified blood can be provided for clinical needs, which is equivalent to a comprehensive and detailed blood test for you. Detailed results will be available one week after blood donation, and experienced physicians will provide consultation and guidance.

6. Voluntary blood donors and their immediate family members (parents, children) and spouse will receive free blood. I will enjoy three times the amount of blood I donated within three years and the same amount of blood after three years. If the amount exceeds 800 ml, I will have unlimited blood use, and my immediate family members and spouse will enjoy the same amount of blood. It fully embodies the idea of ​​"everyone for me and I for everyone". At the same time, it is also a full reflection of your "love, filial piety, and care", that is, love for others, filial piety to parents, and care for your wife and children.
