Cov khoom siv no yog tsim los ntawm kev sib tw indirect immunochromatography technology, nyob rau hauv uas pendimethalin nyob rau hauv cov qauv sib tw rau cov colloid kub sau cov tshuaj tiv thaiv nrog pendimethalin coupling antigen ntes ntawm cov kab xeem ua rau kev hloov xim ntawm cov kab xeem. Cov xim ntawm Kab T yog tob dua lossis zoo ib yam li Kab C, qhia tias cov pendimethalin hauv cov qauv yog tsawg dua LOD ntawm cov khoom siv. Cov xim ntawm kab T tsis muaj zog tshaj kab C lossis kab T tsis muaj xim, qhia tias pendimethalin hauv cov qauv yog siab dua LOD ntawm cov khoom siv. Txawm hais tias pendimethalin muaj los yog tsis muaj, kab C yuav ib txwm muaj xim los qhia tias qhov kev sim no siv tau.
