Establishment of reference intervals for platelet-related parameters in the elderly in Longquanyi District of Chengdu
Objective To establish the reference intervals for platelet-related parameters among the elderly population in Longquanyi District,Chengdu.Methods From November 1st to December 31st 2021,elderly individuals aged between 60 and 80 years were selected from the Longquanyi branch of a natural population cohort study initiated by West China Hospital of Sichuan University in 2021.Complete blood cell analysis was performed to obtain the platelet-related parameters.IBM SPSS Statistics 25 software was used to analyze the data and establish the reference intervals for platelet-related parameters among the elderly population in Longquanyi District.Results A total of 1 938 reference individuals were selected by inclusion and exclusion criteria,and finally 1669 reference individuals,including 665 males and 1004 females,were included to establish the reference intervals after excluding outliers.The reference range of blood platelet count was(95.03-301.32)x109/L for elderly men and(112.13-320.75)×109/L for elderly women,respectively.The reference range of mean platelet volume was 8.97-13.80 fL for elderly men and 9.10-13.90 fL for elderly women,respectively.The reference range of plateletcrit was 0.13％-0.30％for elderly men and 0.14％-0.32％for elderly women,respectively.The reference range of platelet distribution width was 15.80-16.90 for elderly men and 15.70-16.90 for elderly women,respectively.Conclusion It is of practical significance to establish platelet-related parameters in the elderly in local region.
