Evaluating the Relationship of Fasting Capillary and Venous Blood Sugar Level in Self-Glucose Monitoring Device, Fasting Plasma Glucose Level and Glycosylated Hemoglobin (HbA1C) (original) (raw)

Establishing the accuracy of glucose meters however is challenging. A Quantitative Survey research approach was employed in this study under 254 samples, those who are advised for HbA1C test. Baseline data were collected with the help of interview schedule and clinical data of the subjects by a self structured Questionnaire. Subjects were selected by the help of Non-probability purposive sampling technique. Four different parameters were fasting capillary blood sugar value, fasting venous blood sugar value, which were measured through selfglucose monitoring device, fasting plasma glucose level and the HbA1C value of that same sample collected from lab. There is a small but significant difference in the blood glucose results analyzed. So in clinical practice, bedside blood glucose measurements through glucometer may be used by capillary derived specimens and a degree of caution should be worked out in the interpretation of bedside glucometer measurements as they may not be sufficiently accurate to replace laboratory blood glucose results.
