The Hemoglobin Distribution of Korean Blood Donors / 대한수혈학회지

ABSTRACT

BACKGROUND: The current donor selection criteria need to be revised to ensure a reliable blood supply and for donor protection. This study was conducted to analyze the distribution of hemoglobin (Hb) levels of blood donors and to estimate the change of eligible donors when using the revised Hb criterion. METHODS: The Hb levels of all the blood donors who visited the Korean Red Cross Blood Center (KRCBC) between November 9th, 2010 and November 15th, 2010 were measured with a portable hemoglobinometer (HemoCue). The Hb levels of all the eligible donors and some of the deferred donors who visited the Hanmaeum Blood Center (HBC) from April 26th, 2010 to April 30th, 2010 and from November 9th, 2010 to November 15th, 2010 were measured with a portable hemoglobinometer (Hemo_Control). RESULTS: A total of 7,521 donors (6,500 eligible donors and 1,021 deferred donors) were enrolled. The donation eligibility rate at the KRCBC, which is where all the donors were examined, was 84.2% (3,409/4,049) and the deferral rate was 15.8% (640/4,049). The percent of blood donors whose Hb level was less than 12.5 g/dL was 2.1% of the men (44/2,145) and 34.9% of the women (664/1,904), respectively. The percent of female deferred donors with a Hb level of 12.0~12.4 g/dL was 19.3% (109/564) and the percent of male eligible donors with a Hb level of 12.5~12.9 g/dL was 2.6% (54/2,069). At the HBC, and with some deferred donors being excluded, the deferral rate of males and females was 2.0% (36/1,799) and 20.6% (345/1,673), respectively. CONCLUSION: About 20% of the female deferred donors could be expected to participate when a less strict Hb criterion (> or =12.0 g/dL) is applied. This study is thought to be helpful in order to determine the number of donors according to the Hb criteria and to create improved criteria.
