A patient with undetectable hemoglobin A(1c).
A blood sample from a 39-year-old female patient with newly diagnosed type 2 diabetes was assayed for hemoglobin (Hb) A1c on a Bio-Rad D10 HPLC platform. No peak for A1c was seen on the chromatogram (Fig. 1A), and the result was reported as 0%. A complete blood count was clinically significant for an Hb concentration of 10.9 g/dL (reference interval 12–15 g/dL) and a mean corpuscular volume of ...
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 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 کاملHemoglobin A1c: Clinical applications and analytical considerations
Diabetes Mellitus (DM) is the most common disorder of carbohydrate metabolism. Hyperglycemia is the common feature of DM. Hyperglycemia causes cardiovascular, renal, ocular, and peripheral nerve disorders in patients with diabetes. Glycemic regulation plays an essential role in controlling these complications. Thus, evaluation of the glycemic control status is crucial in the management of DM. H...
متن کاملDiabetes screening with hemoglobin A1c prior to a change in guideline recommendations: prevalence and patient characteristics
BACKGROUND In January 2010, the American Diabetes Association recommended the use of hemoglobin A1c (Hgb A1c) to screen and diagnose diabetes. This study explored the prevalence and clinical context of Hgb A1c tests done for non-diabetic primary care patients for the three years prior to the release of the new guidelines. We sought to determine the provision of tests in non-diabetic patients ag...
