[The correlation of serum specific IgE detection and skin prick test in allergic rhinitis]. 2013
OBJECTIVE To investigate the correlation between serum specific immunoglobin E(sIgE) and skin prick test(SPT) and their differences of the positive rate. METHODS 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. RESULTS 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). CONCLUSIONS 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.
