Blood Donation Requirements
Blood Donation Requirements – Detailed Study Notes
1. Basic Eligibility Requirements
Age:
- Minimum age is 16–17 years, though this varies by state.
- Parental consent may be required for donors under 18.
Weight:
- Donors must weigh at least 110 lbs (50 kg).
General health:
- Individuals must feel well and healthy on the day of donation.
Identification:
- A valid ID is required to verify eligibility.
2. Vital Signs Requirements
Temperature:
- Must be less than or equal to 37.5°C (99.5°F).
Pulse:
- Acceptable range is between 50–100 beats per minute (bpm).
- Athletes may have a lower resting pulse.
Blood Pressure:
- Systolic blood pressure should range from 90 to 180 mmHg.
- Diastolic blood pressure should range from 50 to 100 mmHg.
3. Hemoglobin/Hematocrit Requirements
Hemoglobin levels:
- Minimum of 12.5 g/dL for women.
- Minimum of 13.0 g/dL for men.
Hematocrit levels:
- Must be at least 38%.
Importance:
- These requirements help prevent donor anemia and ensure donor safety during the donation process.
4. Donation Frequency
Whole blood:
- Donations are allowed every 56 days.
Platelets:
- Donations can occur every 7 days, with a maximum of about 24 times per year.
Plasma:
- Donations permissible every 28 days.
Double RBC donation:
- Can be done every 112 days.
5. Deferral Types
Temporary Deferrals:
- Recent illness or infection:
- Donors are deferred until recovery.
- Recent vaccination:
- Timing depends on the type of vaccine received.
- Pregnancy:
- Donors are deferred until after delivery.
- Low hemoglobin levels:
- Deferral until levels return to normal.
- Recent tattoo/piercing:
- Deferral may apply depending on regulations and facility standards.
- Travel to malaria-endemic areas:
- Time frame for deferral varies based on exposure specifics.
Permanent Deferrals:
- HIV/AIDS:
- Permanent deferral for individuals testing positive.
- Hepatitis B or C:
- Permanent deferral following positive tests.
- IV drug use (non-prescribed):
- Permanent deferral for individuals with a history of illegal drug use.
- Certain cancers:
- Permanent deferral for individuals with blood cancers.
- Variant Creutzfeldt-Jakob disease risk:
- Individuals at risk are permanently deferred from donating.
6. Infectious Disease Screening
- Tests conducted include:
- HIV-1/2:
- Screening for human immunodeficiency virus.
- Hepatitis B & C:
- Screening for hepatitis viruses B and C.
- Syphilis:
- Testing for the syphilis infection.
- HTLV-I/II:
- Testing for human T-lymphotropic viruses types I and II.
- West Nile Virus:
- Specific screening for this mosquito-borne virus.
- Zika Virus:
- Screening in certain geographic regions.
7. Medications Affecting Donation
- Medications and deferral times include:
- Isotretinoin (Accutane):
- Donors must defer for 1 month following cessation.
- Finasteride:
- Deferral period of 1 month.
- Dutasteride:
- Donors must defer for 6 months afterwards.
- Warfarin:
- Deferral until the treating condition resolves.
- Aspirin:
- Affects only platelet donation; should be noted by donors.
8. High-Risk Behaviors (Screening)
- Behaviors under scrutiny:
- IV drug use:
- History of illegal drug use raises significant concern.
- Multiple sexual partners:
- Increases risk for sexually transmitted infections.
- Recent exposure to HIV:
- A potential risk factor for the safety of blood products.
- Recent tattoos/piercings:
- Done in non-regulated facilities may raise risk of infection.
9. Special Considerations
Menstruation:
- Women may donate during menstruation as long as they feel well.
Fasting:
- Not recommended prior to donation; should maintain regular dietary habits.
Hydration:
- Important to stay hydrated before the donation process.
Iron levels monitoring:
- Essential for donors who donate frequently to ensure safe levels.
10. Blood Donation Process (Quick Review)
- Steps involved in blood donation:
- Registration and ID verification:
- Confirming donor identity and eligibility.
- Health history questionnaire:
- Explores donor’s medical and health background.
- Mini physical examination:
- Checking vital signs and hemoglobin levels.
- Blood collection:
- Approximately 450–500 mL of blood is drawn.
- Post-donation observation:
- Donors are monitored for 10–15 minutes after the donation.
