I also want to donate blood. Do I need to meet the conditions of what?

Article < < Blood donation is free of charge, why do you charge for blood? (Click to read) > >, we talked about the current situation of blood donation without compensation.

After reading the article, many readers expressed their willingness to donate blood, but they did not know whether blood donation should meet the conditions of what. One after another, they left messages asking, I am old, I have hypertension, I have just been vaccinated, I have hepatitis but now I am well… Can these situations donate blood?

Today, let’s talk about it.

These conditions have to be met first

STEP 1 Become an adult

< < Blood Donation Law > > advocates that the age range of people participating in blood donation is 18-55 years old, but this is [advocacy] rather than [hard limit]. If you are hale and hearty, even if you are 60 years old, you can also give a bag of blood.

Step 2: Not too light

Men are more than 50kg and women are more than 45kg. It is too light for the staff to have the heart to draw blood.

3. Stable blood pressure

If the high pressure is higher than 140 mmHg or lower than 90 mmHg, it is better to stabilize your blood pressure before donating blood.

4. Other Conditions

Generally speaking, before blood donation, the staff of the blood center or blood donation point will also conduct a simple physical examination of the blood donor. After the examination is normal, the next step can be taken.

Preliminary blood test

A preliminary examination of the blood of the donor is carried out. The following are usually tested:

1. Clarify ABO blood type;

2. Rapid detection of hepatitis B, hepatitis C and HIV antibodies;

3. Screening syphilis infection;

4. Detection of alanine aminotransferase (ALT) to simply judge liver function;

5. Detect hemoglobin to see if anemia exists;

6. Others, for example, Plasmodium will be tested in areas with high incidence of malaria, Rh blood type will be tested in areas with conditions and areas with high Rh negative rate, etc.

If problems are found in these tests, the blood center will usually notify the blood donor by phone or text message so that the blood donor can go to the hospital in time for further examination and confirmation.

Can I donate blood after being vaccinated?

Let’s compare it.

1. Live vaccines for measles, mumps, yellow fever and poliomyelitis can be donated two weeks after the last vaccination.

2. Rubella live vaccine, animal serum and antitoxin can be donated four weeks after the last vaccination.

3. Rabies vaccine, four weeks after the last vaccination, or one year after rabies vaccine was last vaccinated after rabies bite;

4. Receive hepatitis B human immunoglobulin injection and donate blood one year later;

5. Healthy people receive hepatitis a, hepatitis B, typhoid, DPT and influenza vaccines and can donate blood after one day.

Temporary inability to donate blood

The following are some common cases of temporary inability to donate blood.

1. Wash teeth for less than three days; Less than half a month for tooth extraction or other minor operations; Appendectomy, hernia repair, tonsil surgery and ophthalmic surgery take less than three months. Or less than half a year after a major operation.

2. Cold, acute gastroenteritis and local skin inflammation healed less than one week, generalized inflammation healed less than two weeks, acute urinary tract infection healed less than one month, pneumonia healed less than three months.

1. STD, leprosy and AIDS patients and HIV-infected persons.

2. Patients with hepatitis, hepatitis B virus surface antigen positive, hepatitis C virus antibody positive.

3. Patients with allergic diseases and recurrent allergies, such as recurrent urticaria, bronchial asthma and drug allergy (simple urticaria cannot donate blood during acute attacks).

4. Various tuberculosis patients, such as tuberculosis, renal tuberculosis, lymph node nucleus and bone tuberculosis, etc.

5. Patients with circulatory diseases, such as various heart diseases, hypertension, hypotension, arteriosclerosis, myocarditis, etc.

6. Patients with respiratory diseases, such as chronic bronchitis, emphysema and bronchiectasis and pulmonary insufficiency.

7. Patients with digestive system diseases, such as severe gastric and duodenal ulcer, chronic gastroenteritis, chronic pancreatitis, etc.

8. Patients with urinary system diseases, such as acute and chronic nephritis, chronic urinary tract infection, nephrotic syndrome,

9. Patients with hematological diseases, such as anemia, leukemia, polycythemia vera and various infectious and coagulant diseases.

10. Patients with endocrine diseases, such as diabetes and hyperthyroidism.

11. Patients with chronic skin diseases, especially infectious, allergic and inflammatory systemic skin diseases, such as generalized eczema and systemic psoriasis.

12. Patients with organic neurological diseases or mental diseases, such as encephalitis, sequelae of brain injury, epilepsy, schizophrenia, hysteria, severe neurasthenia, etc.

18. Other circumstances under which the physical examination doctor believes that blood donation cannot be carried out.

In short, in a nutshell, if one has a disease, the top priority is to treat one’s own disease first, donate blood and help others, and do it not too late when one keeps one’s body healthy.

According to the standard blood donation process, before blood donation, blood donors need to fill in an informed consent form and a health status inquiry form, which must be filled in truthfully. If you know that you cannot donate blood, but hide it, on the one hand, it is not good for your health, on the other hand, it will also bring risks to the recipients, and it is necessary to investigate legal responsibilities when it is serious.

Of course, the blood recipients also don’t have to worry too much about the safety of the blood used. After blood donation, the blood will also go through layers of strict quality inspection, and carefully preserved to ensure the quality. The hidden dangers that blood transfusion may have, as well as scientific coping strategies, will be mentioned in the popular science content after that.

If you find that you meet the above-mentioned blood donation conditions and are willing to donate blood once, you may as well try it. In fact, the national and local governments still have some incentive measures for unpaid blood donors, such as giving priority to blood supply, free blood use, gifts, medals, free tickets to scenic spots, etc. This, we will continue to talk next time.
