Study Notes
Blood Donation Guidelines
- Some countries mandate labeling blood from specific donors and informing recipients about the transfusion source.
- Required hemoglobin (Hb) levels:
- Males: > 13 g/dL
- Females: > 12 g/dL
- Autologous donation minimum: 11 g/dL (PCV = 33%).
Donor Acknowledgment
- Donors must read and sign a declaration regarding the risk of HIV transmission through blood and plasma.
- Blood will be tested for HIV and other disease markers; potential deferrals if the risk of transmission exists.
- Names of donors who test positive for risk factors are placed on a permanently deferred list.
Complications in Blood Compatibility
- Multi-transfused patients can have antibodies that complicate blood compatibility; family members may need to provide components.
- Example: Infants with neonatal alloimmune thrombocytopenia may need platelets from the mother.
Antiplatelet Medication Deferral Periods
- Important medication-based deferral timelines for blood donation:
- 48 hours for aspirin, aspirin-containing medications, and Feldene (anti-inflammatory).
- 14 days for clopidogrel (Plavix), ticlopidine (Ticlid), ticagrelor (Brilinta), and prasugrel (Effient).
- Clopidogrel is a selective inhibitor that affects ADP binding to the P2Y12 receptor, impairing platelet aggregation through GPIIb/IIIa complex inhibition.
