Hemoglobin A1C Alternatives
Fructosamine (glycated serum protein) testing may be used to help a person with diabetes monitor and control his or her blood glucose level. The level of fructosamine in the blood is a reflection of glucose levels over the previous 2-3 weeks as opposed to Hemoglobin A1C which looks at every 3 months.
