目的
2
探讨陕西地区成年人凝血因子活性水平,重建西门子凝血因子活性检测试剂盒的成年人参考区间。
方法
2
选取 2023年1月至2024年9月于空军军医大学第一附属医院进行凝血因子活性检测的体检或就诊的人员,根据纳入标准,本研究最终纳入391例18~60岁健康成年受试者,年龄分段标准分为3组,青年组(18~28岁,
n
=312)、中青年组(29~38岁,
n
=64)和中老年组(39~60岁,
n
=15),均使用Sysmex C5100凝血分析仪及配套西门子凝血因子检测试剂检测凝血因子Ⅱ(Factor Ⅱ,FⅡ)、FⅤ(Factor Ⅴ)、FⅦ(Factor Ⅶ)、FⅧ(FactorⅧ)、FⅨ(Factor Ⅸ)、FⅩ(Factor Ⅹ)、FⅪ(Factor Ⅺ)和FⅫ(Factor Ⅻ)的活性,比较各组间凝血因子活性差异,采用非参数法构建各因子的参考区间并对新旧参考区间进行验证。
结果
2
FV因子活性在各年龄组间差异存在统计学意义(
χ
2
=10.99,
P
<
0.001),线性回归分析发现纳入人群的FⅡ活性随年龄减低(
P
=0.006),FⅤ(
P
=0.
001)和FⅧ(
P
=0.008)活性随年龄增加。FⅨ(
t
=3.613,
P
<
0.001)和FⅩ(
t
=4.892,
P
<
0.001)活性在性别分组中的差异具有统计学意义。新建参考区间FⅡ(86%~152%)、FⅤ(78%~156%)、FⅦ(65%~155%)、FⅧ(77%~151%)、FⅨ(64%~117%)、FⅩ(69%~158%)、FⅪ(63%~122%)和FⅫ(44%~126%),通过2轮验证实验,原参考区间全部无法通过验证,新参考区间全部通过验证。
结论
2
凝血因子活性在不同年龄段有差异,且随年龄变化趋势不一致,西门子试剂盒的参考区间无法满足临床需要,本研究自建参考区间性能更具有优势。
Objective
2
To investigate the level of coagulation factor activity among adults in Shaanxi,China,and to reestablish the reference interval of coagulation factor activity for adults measured by Siemens coagulation factor assay kit.
Methods
2
The individuals who underwent physical examination or attended The First Affiliated Hospital of Air Force Medical University from January 2023 to September 2024 and underwent coagulation factor activity testing were selected,and according to the inclusion criteria,391 healthy adults,aged 18-60 years,were enrolled and divided into 18-28 years group with 312 adults,29-38 years group with 64 adults,and 39-60 years group with 15 adults. The Sysmex C5100 coagulation analyzer and the Siemens coagulation factor test reagent were used to measure the activity of Factor Ⅱ(FⅡ),Factor Ⅴ(FⅤ),Factor Ⅶ(FⅦ),Factor Ⅷ(FⅧ),Factor Ⅸ(FⅨ),Factor Ⅹ(FⅩ),Factor Ⅺ(FⅪ),and Factor Ⅻ(FⅫ),and the activity of these coagulation factors were compared between the groups. The nonparametric method was used to establish the reference intervals for each factor and verify the old and new reference intervals.
Results
2
There was a significant difference in the activity of FV between the different age groups(
χ
2
=10.99,
P
<
0.01). Linear regression analysis showed that FII activity decreased with age in all included populations(
P
=0.006),and FV(
P
=0.001) and FⅧ(
P
=0.008) activity increased with age. There were significant differences in the activity of FⅨ(
t
=3.613,
P
<
0.001) and FX(
t
=4.892,
P
<
0.001) between different sex groups. New reference intervals were establish for FⅡ(86%-152%),FV(78%-156%),FⅦ(65%-155%),FⅧ(77%-151%),FⅨ(64%-117%),FⅩ(69%-158%),FⅪ(63%-122%),and FⅫ(44%-126%),and after two rounds of verification tests,the original reference intervals failed the test,while the new reference intervals passed the test.
Conclusion
2
The activity of coagulation factors varies across different age groups,with an inconsistent changing trend with age. The reference interval of Siemens kit cannot meet the clinical needs,and the reference intervals established in this study have more advantages.
