Objective:
To understand the iron stores of the plateletpheresis donors, so as to provide some new experimental data for further exploration and more perfect health examination criteria of the plateletpheresis donors.
Methods:
A total of 297 plateletheresis donors conformed to standard in October 2018 were selected by the cross sectional study. The related factors affecting iron stores were analyzed; the effect of plateletpheresis times of donation on the levels of the hemoglobin(Hb) and serum ferritin(SF) as well as the iron deficency rate in the blood donors was also analyzed; the iron stores in the blood donors was evaluated.
Results:
The SF level in plateletpheresis donors negatively correlated with annual plateletphersis times of donation(r=-0.416, P<0.001); The SF level decreased with the increase of annual times of donation(P<0.05); The iron deficiency rate in plateletpheresis donors showed the increase trend with the increase of annual times of donation. The iron deficiency rate in male and femal with 18-23 times of donation was 12.5%(8/64) and 40%(6/15) respectively.
Conclusion:
The blood center should reduce recruitment frequency and increase the testing of SF for regularly plateletpheresis donors.
