A glycated hemoglobin assay utilizes a simple procedure for the determination of DCCT Standardized %GHb in whole blood samples. First a lysed whole blood sample is incubated with a solid phase that is coupled with boronic acid or similar boronate compound through covalent linkage chemistries known in the art. Next a labeled antibody to , human hemoglobin is added and the resulting signal is directly proportional to the %GHb in the sample. The advantages of measuring %GHb using a single determination include high precision and since the assay is easily automatable, high throughput. With automation this , assay can also be consolidated with other testing on one analyzer. The method …
