Abstract: Objective To understand the distribution characteristic of fat blood in whole blood donators,subsequently provide targeted approach in the system of blood donation. Methods The incidence rate of fat blood in 2013-2015 was analyzed according to year,gender,donation location and time of donation.Results In the past three years,the incidence rate of fat blood dropped from 3.70% in 2013 to 2.39% in 2015. It is more common in male donors and can increase with age. Organization group donators have the lowest incidence,whilst the highest rate was seen in donations at street donation stations. The incidence of fat blood was higher in post-prandial donation in comparison to pre-prandial donations. Conclusion Reinforcing quality control before blood collection is a key factor in reducing fat blood.
