The invention provides an immunological analytical method and devices for determination of the advanced glycosylation end products (AGEs), comprising a reagents for determining the AGEs, which comprises a displaying carrier suspension and the antigen or antibody immobilized on the surface of the said displaying carrier; and a test strip, comprising of: a base plate, and constitutive parts provided on the said base plate. After infusing the said reagent into the said test strip, the immunological reaction of the AGEs antigen or antibody can be determined based on the agglutination phenomenon or accompanied changes of absorbance or color and the presence or raised level of the AGEs in the diabetic patient can be known accordingly such that the practitioner can prevent the occurrence of the complications, or block further the progression of the complications at the earlier stage.
