To investigate the correlation between serum specific immunoglobin E(sIgE) and skin prick test(SPT) and their differences of the positive rate.
One hundred and nine patients with allergic rhinitis were detected the serum slgE. The patients had positive symptoms and signs, positive SPT results with at least one allergen.
Specific IgE and SPT results of Dp,Df and Artemisia showed a positive correlation (r = 0.520, 0.4413, 0.764, P < 0.01). sIgE positive rates were 55.0%, 54.1% and 17.4% for Dp, Df and Artemisia respectively, whereas SPT positive rates were 68.8%,79.8% and 27.5% respectively. The difference between the positive rates of the sIgE and SPT was significant (chi2 = 27.93,18. 20,60. 60, are P< 0.01).
There was a good correlation between specific IgE and SPT. SPT is more sensitive than sIgE, but SPT can not substitute for slgE,vice versa.
探讨血清特异性免疫球蛋白E（sIgE）与皮肤点刺试验（SPT）之间的相关性及其阳性率的差异。
对109例变应性鼻炎患者检测血清sIgE。这些患者有阳性症状和体征，且SPT结果显示对至少一种变应原呈阳性。
粉尘螨、屋尘螨和艾蒿的特异性IgE与SPT结果呈正相关（r = 0.520、0.4413、0.764，P < 0.01）。粉尘螨、屋尘螨和艾蒿的sIgE阳性率分别为55.0%、54.1%和17.4%，而SPT阳性率分别为68.8%、79.8%和27.5%。sIgE与SPT阳性率之间的差异有统计学意义（χ2 = 27.93、18.20、60.60，P均< 0.01）。
特异性IgE与SPT之间存在良好的相关性。SPT比sIgE更敏感，但SPT不能替代sIgE，反之亦然。
