How Much to Give Blood: Understanding Donation Guidelines

Giving blood is a selfless act that can save lives. However, it’s essential to understand the guidelines and requirements to ensure the safety of both the donor and the recipient. At HOW.EDU.VN, our team of experienced medical professionals can provide personalized guidance and answer any questions you may have about blood donation eligibility, ensuring a smooth and informed donation experience. Knowledge about blood donation amount, eligibility and health factors are interconnected.

1. General Guidelines for Blood Donation

Before donating blood, it’s crucial to meet certain general health requirements. These are in place to protect your well-being and the safety of the blood supply.

1.1 Age and Weight Requirements

Generally, donors must be at least 16 or 17 years old (depending on state law) and weigh at least 110 pounds. Some donation centers may have slightly different age or weight requirements, so it’s always best to check with the specific organization beforehand.

1.2 Overall Health and Well-being

You should be in good health and feeling well on the day of donation. This means you should be free from any symptoms of illness, such as fever, cough, sore throat, or body aches. If you’re not feeling your best, it’s best to postpone your donation until you’ve fully recovered.

1.3 Medical History and Medications

Your medical history and any medications you’re currently taking will be reviewed to determine your eligibility to donate. Certain medical conditions and medications may temporarily or permanently disqualify you from donating blood. It’s important to be honest and upfront about your medical history to ensure the safety of the blood supply.

2. Specific Medical Conditions and Blood Donation

Certain medical conditions can affect your eligibility to donate blood. Here’s a breakdown of some common conditions and their impact on donation eligibility:

2.1 Allergies

If you have allergies but feel well, have no fever, and can breathe easily, you are generally acceptable to donate blood.

2.2 Asthma

If you have asthma, you can still donate blood as long as your daily activities are not limited, you are not having difficulty breathing, and you feel well. Medications for asthma do not disqualify you from donating.

2.3 Bleeding Conditions

If you have a history of bleeding problems, you will be asked additional questions. If your blood does not clot normally, you cannot donate due to the risk of excessive bleeding where the needle was placed. Similarly, you should not donate if you are taking any “blood thinner” medications, such as:

• Atrixa (fondaparinux)
• Coumadin (warfarin)
• Eliquis (apixaban)
• Fragmin (dalteparin)
• Heparin
• Jantoven (warfarin)
• Lovenox (enoxaparin)
• Pradaxa (dabigatran)
• Savaysa (edoxaban)
• Warfilone (warfarin)
• Xarelto (rivaroxaban)

If you are taking aspirin, it is generally acceptable to donate leukopaks or whole blood through the Specialized Donor Program. Donors with clotting disorder from Factor V who are not on anticoagulants are eligible to donate; however, all others must be evaluated by the health historian at the collection center.

2.4 Blood Pressure (High or Low)

High Blood Pressure: You can donate as long as your blood pressure is at or below 180 systolic (first number) and at or below 100 diastolic (second number) at the time of donation. Medications for high blood pressure do not disqualify you.

Low Blood Pressure: You can donate as long as you feel well when you come to donate and your blood pressure is at or above 90 systolic (first number) and at or above 50 diastolic (second number).

2.5 Cancer

Eligibility depends on the type of cancer and treatment history. If you had leukemia or lymphoma, including Hodgkin’s Disease and other cancers of the blood, you are not eligible to donate. Other types of cancer are acceptable if the cancer has been treated successfully and it has been more than 12 months since treatment was completed and there has been no cancer recurrence during this time. Lower risk in-situ cancers including squamous or basal cell cancers of the skin that have been completely removed and healed do not require a 12-month waiting period.

Precancerous conditions of the uterine cervix do not disqualify you from donation if the abnormality has been treated successfully. Discuss your particular situation with the health historian at the time of donation.

2.6 Chronic Illnesses

Most chronic illnesses are acceptable as long as you feel well, the condition is under control, and you meet all other eligibility requirements.

2.7 Creutzfeldt-Jakob Disease (CJD)

If you ever received a dura mater (brain covering) transplant that was from an animal or another person you are not eligible to donate. If you received an injection of cadaveric pituitary human growth hormone (hGH) you cannot donate. Human cadaveric pituitary-derived hGH was available in the U.S. from 1958 to 1985. Growth hormone received after 1985 is acceptable. If you have been diagnosed with vCJD, CJD or any other TSE or have a blood relative diagnosed with genetic CJD (e.g., fCJD, GSS, or FFI) you cannot donate.

2.8 Diabetes

Diabetics who are well controlled on insulin or oral medications are eligible to donate.

2.9 Heart Disease

In general, you can donate if you have been medically evaluated and treated, and within the last 6 months, have no new diagnosis, no heart-related symptoms such as chest pain, no new treatment for the condition, no surgery to correct or diagnose the condition, and have no limitations or restrictions on your normal daily activities.

Wait at least 6 months following an episode of angina or a heart attack.

If you have a pacemaker, you can donate as long as your pulse is between 50 and 100 beats per minute and you meet the other heart disease criteria. Discuss your particular situation with your personal healthcare provider and the health historian at the time of donation.

If you have any of the following heart conditions, you are not eligible to donate: Aneurysm, Angiogram, Aortic insufficiency, Aortic Regurgitation, Aortic stenosis, AV malformation, Bicuspid aortic valve-not repaired, Bundle branch block right or left, Cardiomyopathy, Cardiac myxoma, Carotid endarterectomy, Congestive heart failure, Floppy mitral valve, Internal automatic defibrillator, Mitral insufficiency, Mitral regurgitation, Mitral valve prolapse, Polyarteritis nodosa, Pulmonary edema, Tetralogy of Fallot, or Wolff Parkinson White.

2.10 Heart Murmur, Heart Valve Disorder

Acceptable if you have a heart murmur as long as you have been medically evaluated and treated and have not had symptoms in the last 6 months and have no restrictions on your normal daily activities.

2.11 Hemochromatosis

If you have hemochromatosis you are not eligible to donate in the Leukopak/Specialized Donor Program.

2.12 Hemoglobin, Hematocrit, Blood Count

In order to donate blood, a woman must have a hemoglobin level of at least 12.5 g/dL, and a man must have a hemoglobin level of at least 13.0 g/dL. For all donors, the hemoglobin level cannot be greater than 20 g/dL.

2.13 Hepatitis, Jaundice

If you have signs or symptoms of hepatitis (inflammation of the liver) caused by a virus, or unexplained jaundice (yellow discoloration of the skin), you are not eligible to donate blood. If you ever tested positive for hepatitis B (after age 11) or hepatitis C at any age, you are not eligible to donate, even if you were never sick or jaundiced from the infection.

2.14 Hepatitis Exposure

If you live with or have had sexual contact with a person who has hepatitis, you must wait 12 months after the last contact.

Persons who have been detained or incarcerated in a facility (juvenile detention, lockup, jail, or prison) for 72 hours or more consecutively (3 days) are deferred for 12 months from the date of last occurrence. This includes work release programs and weekend incarceration. These persons are at higher risk for exposure to infectious diseases.

Wait 12 months after receiving a blood transfusion (unless it was your own “autologous” blood”), non-sterile needle stick or exposure to someone else’s blood.

2.15 HIV, AIDS

Do not give blood if you have AIDS or have ever had a positive HIV test, or if you have done something that puts you at risk for becoming infected with HIV.

You are at risk for getting infected if you:

2.18 Monkeypox (exposure or diagnosis)

Monkeypox infection or exposure, wait a minimum of 21 days.

2.19 Malaria

Malaria is transmitted by the bite of mosquitoes found in certain countries and can be transmitted to patients through blood transfusion. Blood donations are not tested for malaria because there is no sensitive blood test available for malaria.

If you have traveled or lived in a malaria-risk country, a waiting period is required before you can donate blood.

• Wait 3 years after completing treatment for malaria.
• Wait 12 months after returning from a trip to an area where malaria is found.
• Wait 3 years after living more than 5 years in a country or countries where malaria is found.

3. Frequency of Blood Donation

How often you can donate blood depends on the type of donation:

3.1 Whole Blood Donation

You can donate whole blood every 56 days, up to six times a year. This allows your body time to replenish the red blood cells lost during donation.

3.2 Platelet Donation

Platelets can be donated more frequently, as often as every 7 days, up to 24 times a year. This is because platelets are replaced more quickly by the body than red blood cells.

3.3 Plasma Donation

Plasma donation has a similar frequency to platelet donation, with the possibility of donating every 28 days, and up to 13 times a year.

3.4 Double Red Cell Donation

Double red cell donation involves collecting two units of red blood cells during a single donation. You must wait 112 days between double red cell donations.

4. Factors Affecting Blood Donation Eligibility

Several factors can temporarily or permanently affect your eligibility to donate blood:
