小鼠顆粒酶M(GZMM)檢測試劑盒在一步法測定中,，當(dāng)標(biāo)本中受檢抗原的含量很高時,，過量抗原分別和固相抗體及酶標(biāo)抗體結(jié)合，而不再形成"夾心復(fù)合物",。類同于沉淀反應(yīng)中抗原過剩的后帶現(xiàn)象，此時反應(yīng)后顯色的吸光值（位于抗原過剩帶上）與標(biāo)準(zhǔn)曲線（位于抗體過剩帶上）某一抗原濃度的吸光值相同,，如按常法測讀,，所得結(jié)果將低于實(shí)際的含量，這種現(xiàn)象被稱為鉤狀效應(yīng)（hook effect）,，因?yàn)闃?biāo)準(zhǔn)曲線到達(dá)高峰后呈鉤狀彎落,。鉤狀效應(yīng)嚴(yán)重時，小鼠顆粒酶M(GZMM)檢測試劑盒反應(yīng)甚至可不顯色而出現(xiàn)假陰性結(jié)果,。因此在使用一步法試劑測定標(biāo)本中含量可異常增高的物質(zhì)（例如血清中HBsAg,、AFP和尿液hCG等）時，應(yīng)注意可測范圍的zui高值,。用高親和力的單克隆抗體制備此類試劑可削弱鉤狀效應(yīng),。假使在被測分子的不同位點(diǎn)上含有多個相同的決定簇，例如HBsAg的a決定簇,，也可用針對此決定的同一單抗分別包被固相和制備酶結(jié)合物,。但在HBsAg的檢測中應(yīng)注意亞型問題，小鼠顆粒酶M(GZMM)檢測試劑盒HBsAg有adr,、adw,、ayr、ayw4個亞型,，雖然每種亞型均有相同的a決定簇的反應(yīng)性,，這也是用單抗作夾心法應(yīng)注意的問題。
