Objective To establishment of reference intervals for peripheral blood lymphocyte subsets in healthy adult in Yibin.Methods 303 healthy adult indivicuals(172 men and 131 women)aged from 1 years to 86 years were enrolled.Venous anticoagulation was detected within 4 hours.Recommended procedures based on CLSI,sreference for inspection items,and normal distribution method was used to establishment of reference Interval of lymphocyte subsets in age or sex groups.Results The reference intervals of CD3^+(%)in young and middle-aged males,old age group males,young and middle-aged females,old age group females were 53.7%~84.7,45.83%~83.03%,55.45%~85.85%and 48.01%~87.29%respectively,and single sample mean t test with original reference interval(t=6.266,-3.522,9.647,2.259,all P<0.05).The reference intervals of CD3^+(piece/μl)in young and middle-aged group,old age group were 482.37~2 113.53(piece/μl)and 307.35~141.21(piece/μl)respectively,and single sample mean t test with original reference interval(t=-20.859,-36.755,all P<0.05).The reference intervals of CD3^+CD8^+(%)in young age group,middle aged and old group were 16.59%~43.59%and 11.19%~42.23%respectively,and single sample mean t test with original reference interval(t=12.483,3.429,P<0.05).The reference intervals of CD3^+CD8^+(piece/μl)in young and middle-aged,old age group were 73.941~000.08(piece/μl),26.26~818.38(piece/μl),respectively,and single sample mean t test with original reference interval(t=-13.373,-25.518,P<0.05).The reference intervals of CD3^+CD4^+(%)in young age group,middle aged and old group were 20.99%~47.61%,21.91%~53.07%respectively,and single sample mean t test with original reference interval(t=-28.718,-17.541,P<0.05).The reference intervals of CD3^+CD4^+(piece/μl)in all year group was 391.371~1 284.69(piece/μl)respectively,and single sample mean t test with original reference interval(t=-35.178,P<0.05).The reference intervals of CD4^+/CD8^+in young age group,middle aged and old group were 0.43~2.03 and 0.26~2.84 respectively,and single sample mean t test with original reference interval(t=-22.718,-5.671,P<0.05).The reference intervals of CD3^-CD16^+CD56^+(%)in young and middle-aged males,old age group males,young and middle-aged females,old age group females were 3%~34.56%,3.93%~43.63%,2.88%~31.10%and 0.74%~38.52%respectively,and single sample mean t test with original reference interval(t=8.842,15.605,5.537,8.904,all P<0.05).The reference intervals of CD3^-CD16^+CD56^+(piece/μl)in all year group males,all year group females were 47.51~713.67(piece/μl)and 39.49~586.95(piece/μl),respectively,and single sample mean t test with original reference interval(t=1.341,P<0.05 and t=-6.767,P<0.05).The reference interval for CD3^-CD19^+(%)in all year group was 3.32%~18.02%,and single sample mean t test with original reference interval(t=-28.227,P<0.05).The reference interval for CD3^-CD19^+(piece/μl)in all year group was 42.99~353.45(piece/μl),and single sample mean t test with original reference interval(t=-44.576,P<0.05).Except for all year group males in CD3^-CD16^+CD56^+(piece/μl),indicating that the difference between the reference interval and the original reference interval established in this experiment was statistically significant.Conclusion The reference interval of peripheral blood lymphocyte subsets of healthy adults in Yibin area was preliminarily established,which provided a basis for the diagnosis,treatment and evaluation of AIDS and related diseases in Yibin.
