The Effect of Hemoglobin on Blood Sugar Levels During the Donation Phase in Madina, KSA

Abstract

Blood donation requires donors to meet a set of health criteria aimed at ensuring the safety of both the donated blood and the donor. Plasma glucose levels can undergo immediate changes post-donation, yet glucose level screening is not a standard part of the donor selection process. Consequently, individuals with potentially abnormal glucose levels may still qualify to donate, which could pose health risks. This study aimed to assess the random blood glucose (RBG) levels in blood donors before and after donation to determine any significant changes. Blood samples were obtained from the Regional Blood Bank (RBB) at the Madina in KSA . The study included 200 healthy participants aged 18-55 years who met RBB's donor criteria. RBG levels for each donor were measured pre- and post-donation using Accu – check Glucometer analyzer. Most participants fell within the 31-40 age range. The mean RBG concentration was 6.58 ± 1.72 mmol/L before donation and decreased to 6.44 ± 1.64 mmol/L afterward. A 93% confidence interval indicated a statistically significant change (p < 0.001). These findings suggest that RBG levels commonly decrease following blood donation, highlighting the potential importance of pre-donation glucose screening to ensure donor safety.
