Abstract:
Objective To establish and verify the personalized reference interval of blood cells.Methods The results of blood cells from 2 089 health subjects in 2014,2015 and 2016 were collected.The ratio of the later results to the previous results was defined as the fluctuation (λ).The ratio (λ1) of the results of 2015 to the results of 2014 was calculated and λ1 was analyzed statistically to establish the fluctuation reference interval (CIλ).The ratio (λ2) of the results of 2016 to the results of 2015 was calculated.λ2 was used to verify λ2.The personalized reference interval (CIp) was established by multiplying each result of 2015 and CIλ.CIp was verified by results of 2016.The ratio of the upper and lower limits of CIp was calculated.The ratio of the upper and lower limits of the reference interval (WS/T 405) was calculated.Results The values of CIλ were as follows:WBC (0.66 to 1.53),L(0.67 to 1.51),M (0.50 to 2.00),N(0.56 to 1.78),E(0.4 to 2.51),PLT(0.76 to 1.32),RBC(0.92 to 1.12),Hb(0.92 to 1.11),Hct(0.91 to 1.12),MCV(0.95 to 1.07),MCH(0.95 to 1.05)and MCHC(0.94 to 1.06).The validation tests of CIλ and CIp showed that both CIλ and CIp were suitable for this laboratory.Compared with the reference interval of professional criteria,the ratio of the upper and lower limits of the CIp was smaller than that of traditional criteria.Conclusion CIp for this laboratory was established and verified.Compared with traditional criteria,CIp should be more personalized and highly sensitive.
