In the laboratory, only the white part of the blood is used, while the meter uses whole blood (white and red part). According to ISO, a difference of up to +/- 15% is acceptable for results above 100 mg/dL and +/- 15 mg for results below 100 mg/dL.
      Inaccurate results can generate errors, such as: presenting a higher value than the real one, causing the patient to use a higher dose of insulin than necessary, which can cause a hypoglycemic crisis.
