This invention describes a rapid immunochromatographic assay for measuring the ratio of glycated albumin to total albumin in saliva. Patients with diabetes have elevated levels of glucose in their blood that can react with plasma albumin to form glycated albumin. The amount of glycated albumin formed is directly correlated with the level of plasma glucose that the albumin has been exposed to over a period of time. Saliva albumin is derived from plasma albumin and therefore contains glycated and non-glycated albumin fractions that can be measured. The ratio of glycated albumin to total albumin in saliva will provide an indication of the average amount of protein glycation that occurred over the preceding 2-3 week period. The test is performed using a disposable strip that contains the testing reagents and the results are measured in a measuring instrument that automatically reads, calculates and displays the final result. The results of tests performed over a period of time are stored in the instrument's memory and presented in a numerical or graphical format so that the individual's glycated albumin level can be monitored over time.

The invention belongs to the technical field of medicine and relates to an albumin-bound near-infrared fluorescent dye-maleimide conjugate. The albumin-bound near-infrared fluorescent dye-maleimide conjugate specifically replaces chlorine in the conjugated chain of the cyanine dye with a group containing maleimide, and the optical properties are modified by intramolecular charge transfer effects to enable the conjugate to be used as a blue bio-dye. Secondly, the maleimide group in the conjugate can be covalently bound to a free sulfhydryl group at position 34 of cysteine on plasma albumin by aMichael addition reaction, so that the conjugate has excellent lymph node targeting. A near-infrared fluorescent biological imaging agent overcomes the defects of an imaging method used in clinical sentinel lymph node navigation surgery, and is safe, reliable, accurate in positioning, and high in imaging efficiency. The two imaging modes, blue-stained macroscopic recognition and near-infrared fluorescence imaging, are integrated to enable dual imaging function of lymph nodes in vivo.
