  • Patent number: 6316265
    Abstract: A glycated hemoglobin assay utilizes a simple procedure for the determination of standardized %GHb in whole blood samples correlated to the Diabetes Control and Complications Trial (DCCT). 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 according to the various embodiments of the invention thus eliminates the need for two measurements: one for GHb and another for total hemoglobin (THb).
