Labile hemoglobin A1c: unexpected indicator of preanalytical contraindications.
Labile hemoglobin A 1c (Hb A 1c), or pre–Hb A 1c , is an intermediate in the synthesis of Hb A 1c and is characterized by the reversible binding of glucose to Hb as a Schiff base (1). Its biological variation is related to recent fluctuations in glycemia and cannot provide suitable retrospective information on a patient's long-term glycemic balance. Therefore, labile Hb A 1c must be eliminated ...
متن کاملUnexpected hemoglobin A1c results.
A 52-year-old woman with a medical history of hepatitis B, hyperlipidemia, hypertension, anemia, and depression presented to the internal medicine clinic for a routine visit. Laboratory tests 3 months previously had revealed an impaired fasting glucose concentration of 5.9 mmol/L (106 mg/dL) [reference interval, 3.9 –5.6 mmol/L (70 –100 mg/dL)]. Therefore, a hemoglobin (Hb) A1c analysis was per...
متن کاملMeasurement of Hemoglobin A1c
Evaluation of glycemia is used for the diagnosis and management of patients with diabetes. Glucose and hemoglobin A1c (HbA1c) provide complementary information and both are used to assess an individual’s glycemic status. The concentration of glucose in the blood indicates the subject’s glycemia at the time of blood sampling. However, blood glucose concentrations are modified by numerous factors...
متن کاملLabile A1C Is Inversely Correlated With the Hemoglobin Glycation Index in Children With Type 1 Diabetes
OBJECTIVE We hypothesized that labile A1C (LA1C) is directly correlated with stable A1C (SA1C) and between-patient differences in SA1C, which are independent of mean blood glucose (MBG). RESEARCH DESIGN AND METHODS We measured SA1C, LA1C, MBG, and a single clinic capillary glucose (CCG) from 152 pediatric patients with type 1 diabetes. Patients were grouped as high, moderate, or low glycators...
متن کاملGlobal Harmonization of Hemoglobin A1c
Measurement of glycohemoglobin (GHb) is widely used in patients with diabetes mellitus as a monitor of longterm glycemic control (1–3). In addition, prospective randomized clinical trials, most notably the Diabetes Control and Complications Trial (DCCT) and the United Kingdom Prospective Diabetes Study (UKPDS), have demonstrated that GHb is a measure of the risk for the development of diabetes ...
