目的:探讨高原地区新生儿疾病筛查采血方法的改进与假阳性率及复查率的关系。方法:对我院2005年—2007年出生的新生儿随机分两组,分别采用直刺采血法与定位斜刺采血法,观察复查人数及假阳性率。结果:两种采血方法的复查率、假阳性率存在显著性差异(P<0.01)。结论:定位斜刺采血法明显优于直刺采血法,定位斜刺采血法,有效降低新生儿疾病筛查的复查率及假阳性率。
Objective: To explore the relationship between the improvement of blood sampling method and the false positive rate and the review rate in neonatal disease screening in the plateau area. Methods: Neonates born in our hospital from 2005 to 2007 were randomly divided into two groups. The methods of straight pricking blood collection and oblique pricking blood sampling were used respectively to observe the number of reexaminations and the false positive rate. Results: There were significant differences in the rates of reviewing and false positives between the two methods (P <0.01). Conclusion: Oblique oblique lancing method is obviously superior to straight lancing method and positioning oblique lancing method, which can effectively reduce the screening rate and false positive rate of neonatal screening.
