Analysis of hemoglobin A1c from dried blood spot samples with the Tina-quantR II immunoturbidimetric method.

Background: Hemoglobin A1c (HbA1c) has been endorsed as a tool for the diagnosis of diabetes. This test requires instrumentation that may not be available in underdeveloped areas. Dried blood spot (DBS) samples collected by finger stick procedures offer a mechanism to transport samples to laboratories that do measure HbA1c.
