Hemoglobin A1c, Blood

Method Description Describes how the test is performed and provides a method-specific reference

The D-100 hemoglobin A1c (HbA1c) test utilizes principles of ion-exchange high-performance liquid chromatography. The samples are automatically diluted on the D-100 and injected into the analytical cartridge. The D-100 delivers a programmed buffer gradient of increasing ionic strength to the cartridge, where the hemoglobins are separated based on their ionic interactions with the cartridge material. The separated hemoglobins then pass through the flowcell, where changes in the absorbance at 415 nm are measured. The D-100 software collects raw data from each analysis and calculates HbA1c values based on a bilevel calibration curve. The HbA1c area is calculated using an exponentially modified Gaussian algorithm. A sample report and a chromatogram are generated for each sample.(Instruction manual: Bio-Rad D-100 HbA1c Instructions For Use, LB0002870revA; 2014)

Day(s) Performed Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.

Monday through Sunday

Report Available The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.

Same day/1 day

Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

3 days

Performing Laboratory Location Indicates the location of the laboratory that performs the test
