The normal blood test examination does not include HIV testing. The normal health checkup blood test includes items such as routine blood tests, biochemical and hepatitis B tests, through which the number and distribution of blood cells, the presence of anemia, etc. can be understood. If surgery or special examinations are required, pre-operative examinations and preparations for special examinations, such as gastroscopy, and examinations for hepatitis B, hepatitis C, AIDS and syphilis, are also required. When donating blood, in addition to the rapid initial screening before donation, there is also a preliminary examination and reexamination of the blood after donation. If one of the blood items found during the examination does not meet the requirements, the blood cannot be used in clinical practice.
