Introduction: Blood service is a health service that utilizes human blood as a basic ingredient for humanitarian and non-commercial purposes. Donors in Indonesia are required to have a minimum Hemoglobin (Hb) level of 12.5 g/dL in accordance with National Regulations. It aims to ensure that the donor can tolerate the loss of blood without the appearance of anemia symptoms. This study aims to analyze the Hb levels of donors at the Blood Transfusion Service of Dr. Sardjito Hospital, Yogyakarta, Indonesia.
Method: This analytic observational study applied a retrospective design. The data of 62,221 donors were taken from the donor database of the Blood Transfusion Service of Dr. Sardjito Hospital. The inclusion criteria were donors aged ≥ 17 years and met other donor selection criteria. Donors with incomplete data were excluded. The chi-Square test was performed using the SPSS version 22. The p < 0.05 was considered significant.
Results: The subjects were dominated by male donors, i.e., 48,348 (77.7%), and the most Hb level were 14.1-15.5 g/dL. This range of Hb levels was identified as the highest proportion in all age groups. The Hb levels of 14.1-15.5 g/dL were determined in 5,874 (39.6%) blood group A, 7,332 (39%) blood group B; 1,830 (39.6%) blood group AB and 9,486 (39.5%) blood group O donors.
Conclusions: There was a significant difference in the proportion of donors based on Hb levels, sexes, ABO groups, Rhesus D groups, donation types, and donor statuses (p < 0.001).
