Rho(D) blood group should be determined in conditional areas and areas with high Rh negative rate.
3. Alanine aminotransferase: primary screening of negative blood by ketone body powder method.
Detection method: ≤25 units.
4. Hepatitis B virus surface antigen (HBsAg): negative (reagent sensitivity ≤ 1 μ g/ml).
5. Hepatitis C virus (HCV antibody): negative.

3. Those who have recovered from colds and acute gastrointestinal diseases for less than a week, acute urinary tract infections for less than a month, and pneumonia for less than three months.
4. Some infectious diseases: for example, dysentery recovered less than half a year, typhoid fever recovered less than one year, brucellosis recovered less than two years, and malaria recovered less than three years.
5. Those who have close contact with infectious diseases shall be extended to the longest incubation period of the disease from the date of contact.
6. Infusion of whole blood and blood components within one year.
7. Less than half a year after major surgery, less than three months after appendectomy, hernia repair and tonsillectomy.
8, less than a week after the local inflammation of the skin healed; Less than two weeks after extensive inflammation healed.
Six, there are the following circumstances and medical history can not supply blood.
1, Meniere's disease patients.
2, sexually transmitted diseases, leprosy, AIDS and HIV infection.
3. Those who have a history of hepatitis, those who are positive for hepatitis B surface antigen and those who are positive for hepatitis C antibody. However, hepatitis A (with normal transaminase three times in a row) can participate in blood supply one year later.
4. Those with allergic diseases and allergic history of recurrent attacks, such as recurrent urticaria, bronchial asthma and drug allergy (simple urticaria can't supply blood during acute attacks).
5, there are all kinds of tuberculosis patients, such as renal tuberculosis, lymph node tuberculosis, bone tuberculosis and so on.
6. Patients with cardiovascular diseases and their medical history: such as various heart diseases, hypertension, hypotension, hyperlipidemia, myocarditis, thrombophlebitis, etc.
7. Patients with respiratory diseases: such as chronic bronchitis, emphysema, bronchiectasis with pulmonary insufficiency.
8. Patients with digestive system and urinary system diseases: such as severe gastric and duodenal ulcer, chronic gastroenteritis, acute and chronic nephritis, chronic urinary tract infection, nephrotic syndrome, chronic pancreatitis, etc.
9. Patients with various blood diseases: such as anemia, leukemia, polycythemia vera and various bleeding and coagulation diseases.
10, patients with endocrine diseases or metabolic disorders: such as pituitary and adrenal diseases, hyperthyroidism, acromegaly, diabetes insipidus, diabetes, etc.
