Study Notes

Deferral of Blood Donation Due to Medical Conditions

Brucellosis requires permanent deferral from blood donation.
Herpes viruses including type I and II, varicella-zoster, EBV, and CMV necessitate deferral until 28 days after complete recovery.
Permanent deferral is mandated for Human herpes virus 8 (HHV-8).
Syphilis also results in a permanent deferral from donation.

Suitability of Blood for Transfusion

Blood collected from donors may be unsuitable for transfusion due to underlying medical conditions.
Ineligibility can arise if the donor does not meet basic qualification criteria.

Physical Examination Criteria for Blood Donors

General Appearance: Donors appearing ill, influenced by drugs or alcohol, or excessively nervous should be deferred.
Temperature: Must not exceed 37.5 °C (99.5 °F).
Pulse: Should be regular, with a frequency between 60 and 100 beats per minute.

Platelet Donation Guidelines

A minimum of four weeks must pass after the last platelet donation before a new donation can occur.
Platelet count evaluation is crucial post-collection, as plateletpheresis can decrease the count by 30% to 60%.
