The specificities and sensitivities of skin test reactivity to imported fire ant (IFA) whole body extract (WBE) and IFA venom were compared with IFA WBE RAST and IFA venom RAST in the diagnosis of IFA allergy. Study groups consisted of 18 IFA allergic patients and 21 control subjects with no history of allergy to insect stings. All IFA allergic patients had positive skin tests to both IFA WBE and IFA venom. Six of 21 (29%) control subjects also had positive skin tests to both IFA WBE and IFA venom. A commercial IFA WBE RAST was positive in 10 of 18 (56%) IFA-allergic patients and 2 of 21 (10%) control subjects. Imported fire ant aqueous venom RAST was positive in 11 of 11 (100%) IFA-allergic patients and three of ten (30%) control subjects. Vespa IFA venom RAST was positive in 16 of 18 (89%) IFA-allergic patients and 5 of 21 (24%) controls. The sensitivities and specificities of IFA WBE skin testing, IFA venom skin testing, and IFA venom RAST did not differ significantly. Imported fire ant WBE RAST was less sensitive than the other diagnostic methods.
在进口火蚁（IFA）过敏的诊断中，比较了皮肤对进口火蚁全身提取物（WBE）和IFA毒液反应性的特异性和敏感性，并与IFA WBE放射变应原吸附试验（RAST）和IFA毒液RAST进行了比较。研究组包括18名IFA过敏患者和21名无昆虫叮咬过敏史的对照受试者。所有IFA过敏患者对IFA WBE和IFA毒液的皮肤试验均呈阳性。21名对照受试者中有6名（29%）对IFA WBE和IFA毒液的皮肤试验也呈阳性。一种市售的IFA WBE RAST在18名IFA过敏患者中有10名（56%）呈阳性，在21名对照受试者中有2名（10%）呈阳性。进口火蚁水毒液RAST在11名IFA过敏患者中有11名（100%）呈阳性，在10名对照受试者中有3名（30%）呈阳性。黄蜂IFA毒液RAST在18名IFA过敏患者中有16名（89%）呈阳性，在21名对照受试者中有5名（24%）呈阳性。IFA WBE皮肤试验、IFA毒液皮肤试验和IFA毒液RAST的敏感性和特异性无显著差异。进口火蚁WBE RAST比其他诊断方法敏感性更低。
