Summary
Serum iron (SI) levels were analyzed in over 62,000 blood donors. Male donors had higher SI than females, and donor SI decreased with age in men.
Area of Science:
- Biochemistry
- Hematology
- Public Health
Context:
- Blood donation is a critical component of healthcare.
- Monitoring donor health parameters like serum iron is essential for blood safety and efficacy.
- Understanding demographic variations in serum iron is important for blood program management.
Purpose:
- To determine serum iron (SI) levels in a large cohort of blood donors.
- To investigate the relationship between SI levels, sex, and age in blood donors.
- To provide data for optimizing blood donation and transfusion protocols.
Summary:
- Serum iron (SI) levels were measured in 62,054 blood donors (37,989 males, 24,065 females) aged 16-64 years.
- Mean SI was 108.2 ± 39.5 µg/dL in males and 88.5 ± 35.7 µg/dL in females.
- SI showed no significant age-related difference in females but decreased with age in males (20-64 years).
Impact:
- Provides crucial reference data on serum iron levels in blood donors.
- Highlights sex-based differences in serum iron relevant to blood donation criteria.
- Informs age-specific considerations for blood donor screening and management.
- Aids in the strategic planning and operational efficiency of blood programs.

02:45Blood Transfusion and Agglutination
Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

01:19Rh Blood Group
The Rhesus (Rh) antigen is crucial in determining blood groups and ensuring compatibility during blood transfusions.
01:10Blood Typing
Understanding an individual's blood group is a critical component of transfusion medicine. It ensures compatibility in blood transfusions, organ transplants, and even during pregnancy. Determining these blood groups involves the ABO and Rh blood typing systems, utilizing specific antigens and corresponding anti-sera to identify an individual's blood type.
Antigens are protein molecules that reside on the surface of red blood cells (RBCs). The ABO and Rh blood typing systems target antigens A,...
