    Study Notes

    Blood Glucose Monitoring

    • Blood glucose monitoring allows patients with diabetes mellitus to self-manage their disease.
    • The procedure of obtaining capillary blood by skin puncture is less painful than venipuncture.
    • The development of reagent strips, home glucose monitors, and the skin puncture method has revolutionized home management care of patients with diabetes mellitus.

    Methods of Blood Glucose Testing

    • Visually read tests (e.g., Chemstrip bG, Glucostix) do not require an expensive machine but require the patient to visually interpret the results.
    • Blood glucose reflectance meters are lightweight, run on batteries (e.g., AccuChek III, OneTouch), and provide an accurate measurement of blood glucose level in 5 to 50 seconds.
    • Point-of-care (POC) blood glucose testing meters should be dedicated for single-patient use or cleaned and disinfected if not possible.

    Characteristics of Blood Glucose Meters

    • Meters differ in amount of blood needed for each test, testing speed, overall size, ability to store test results in memory, cost of the meter, and cost of test strips.
    • Some larger meters are voice activated, providing support for the older adult or patient with visual impairments.
    • The amount of time to complete glucose testing varies from 5 to 50 seconds.
    • Some meters can be programmed to monitor glucose levels for a continuous 72 hours.

    Advanced Blood Glucose Monitoring Systems

    • Minimally invasive glucose meters use a small, fine plastic sensor inserted through the abdomen and provide continuous readings of blood glucose levels.
    • Biosensors can be taped on the external abdomen and transmit blood glucose levels to a handheld wireless meter.
    • Noninvasive glucose meters use precise laser technology or light beam to puncture the skin, resulting in less damage to tissue.

    Testing of Glycosylated Hemoglobin (HbA1c)

    • HbA1c evaluates the amount of glucose available in the bloodstream over the 120-day life span of a red blood cell.
    • HbA1c provides an accurate long-term index of a patient’s average blood glucose level drawn by venous puncture.
