Le khithi isekelwe kukhuphiswano lwetekhnoloji ye-immunochromatography engathanga ngqo, apho umxholo we-Glycyrrhizic acid kwisampulu ukhuphisana negolide ye-colloid ebhalwe i-antibody enomxholo we-Glycyrrhizic acid edibanisa i-antigen ebanjwe kumgca wovavanyo. Iziphumo zovavanyo zinokujongwa ngeso lenyama.
