Liver and renal function, blood lipids, and blood glucose after blood donation in long-term blood donors aged 45—65 years

Abstract

Objective To investigate the liver and renal function, blood lipids, and blood glucose at 3 months after blood donation in long-term blood donors aged 45-65 years, as well as the possibility of continuing to donate blood after exceeding the age for blood donation. Methods The long-term blood donors who donated blood at our station from September to December 2016 were selected, and according to the age, they were divided into group A (45-49 years of age), group B (50-54 years of age), group C (55-59 years of age), and group D (60-65 years of age). Liver and renal function, blood glucose, and blood lipid levels were measured at 3 months after the most recent blood donation and were compared between groups. Results There was a significant difference in the serum level of low-density lipoprotein cholesterol (LDL-C) at 3 months after blood donation between groups A/B/C and group D (t=2.45-4.61,P<0.05), while there were no significant differences between the four groups in liver and renal function and blood glucose at 3 months after blood donation (P>0.05). Conclusion The long-term blood donors, aged 45-59 years, tend to have stable liver and renal function, blood lipids, and blood glucose at 3 months after blood donation, and long-term blood donation does not affect the above indicators. The blood donors aged 60-65 years have a higher level of LDL-C after blood donation, with other indicators remaining stable, and therefore, they may be considered as potential blood donors.
