The most common type of reaction in blood donors is vasovagal reactions (VVRs). VVRs can negatively affect donor retention. The aim of this study was to assess the frequency of VVRs in Kurdistan Blood Center and impact of VVRs on donor return rates.

A descriptive cross-sectional study was conducted on the donors referring to Blood Center of Kurdistan province in 2015. In addition, donors who had VVRs were evaluated for return donation within 12 months. Results were analyzed by SPSS 16 software and Pearson's correlation was applied for analysis.

A total of 25891 blood donors were enrolled. Of the total number of donors, 170 (0.65%) experienced VVRs (157 male and 13 female); of these, 164 (95.9%) developed mild reaction, 3 (1.8%) had moderate, and 4 (2.4%) developed severe reaction. The mean age of female and male donors who experienced VVRs was 31.4 and 30.73 years, respectively. First-time donors (1.2%) had greater possibility to have a reaction. Donors with hemoglobin less than 15 gr/dl were significantly associated with VVR (p=0.004). The correlation of the body weight with VVR was significant (p=0.008). The return rate within 1 year was 18% (32/170) among donors with VVRs.

The results showed that the frequency of vasovagal reactions is higher in men with a greater weight loss than the minimum defined for blood donation

Detection of ABO blood groups through agglutination is the basis of pre-transfusion testing. However, weak agglutination reactions may be obtained with reagent antibodies and are a result of weak expression of A and B antigens on red blood cell surface which may cause a discrepancy in blood group typing. Here, we report a donor which showed discrepancy between red blood cells (forward) and serum (reverse) typing. A detailed analysis revealed the blood type as a variant of blood group B. Subgroup of B is a very rare phenotype of blood. This is the first case ever detected in Kurdistan blood transfusion Center.

Evaluation of the prevalence of transfusion-transmissible infections (TTIs) in blood donors is a valuable index of donor selection and blood safety. This study was conducted to explore the prevalence and trends of TTIs markers and study of confidential unit exclusion )CUE) option among blood donors in Kurdistan province in the west of Iran.
We conducted a cross-sectional analysis on all volunteer donors from 2007 to 2014. Serologic tests were performed to detect TTIs markers. The seropositive results were confirmed using the confirmatory assays.
Of 197568 cases of the blood donated during 2007 and 2014, 0.29% was positive for Hepatitis B surface antigen, 0.006% for anti-human immunodeficiency virus and 0.06% for anti-hepatitis C virus. The prevalence of human immunodeficiency virus remained stably below 0.02% during the study period whereas the prevalence of Hepatitis B surface antigen showed a downward trend over the period of 8 years. The trend of hepatitis C virus infection frequency had increasing patterns from 2007 to 2009 and decreasing patterns thereafter to 0.05%. CUE was chosen in 1442 (0.7%) donations. Out of this number, 864 (59.9%) were first time blood donors and 578 (40.08%) repeat donors. CUE-positive donations had significantly higher risk of TTIs markers (p The prevalence rate of viral infections has been reduced to low levels in blood donations over the 8 years. Moreover, CUE is considered an effective option for identifying donors with increased risk of TTIs markers.
