GlycoMark®

Specimen Required
Draw blood in a SST. Centrifuge, separate serum from cells and send 1.0 mL serum (0.5 mL minimum) refrigerated in a screw-capped plastic vial.

Alternate Specimen
Plasma: EDTA

Rejection Criteria
Gross hemolysis, plasma other than EDTA

Methodology
Colorimetric, Enzymatic

Stability
Room temperature: 7 days; Refrigerated: 7 days; Frozen: 28 days

Reference Range
<=1 year: Not established
2-17 years: Male: 15.0-38.0 µg/mL
2-17 years: Female: 11.2-35.7 µg/mL
>=18 years: Male: 7.3-36.6 µg/mL
>=18 years: Female: 7.5-28.4 µg/mL
GlycoMark® reference ranges apply to persons without diabetes. In people with diabetes, under good to moderate glycemic control (Hemoglobin A1c levels <=8%), GlycoMark® levels <8 µg/mL suggest significant glycemic variability, most likely due to post meal blood glucose levels increasing above 180 mg/dL
