Test Details
Use
GlycoMark® testing provides an estimate of the patient’s postmeal glucose over a one- to two-week period, making it ideal for intermediate term monitoring of glycemic control in diabetic patients. GlycoMark® testing can also help monitor the effectiveness of therapeutics targeting postprandial glucose (PPG)1,2 and is a useful adjunct to routine A1c testing, because it responds more rapidly and sensitively to hyperglycemia than A1c.1,2
