    Reference notes
    GlycoMark®: • <18 years: Not established • Adult males: 10.7−32.0 μg/mL • Adult females: 6.8−29.3 μg/mL • Glycemic control goal for diabetic patients: >10 Hemoglobin A1c (percent): • Normal: <5.7 • Increased risk for diabetes: 5.7−6.4 • Ongoing hyperglycemia: >6.4 • Estimated average glucose: − Glycemic control for adults with diabetes: <7.0 (ADA) Note: If A1c results are between 6.0 and 8.0 (including 6.0 and 8.0), GlycoMark® testing is performed. GlycoMark® reflects postprandial glucose spikes from the previous two weeks, whereas A1c reflects average glycemic control during the previous three months.

We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
