How To Analyze The Test Results Of Blood Glucose Meter

Self-monitoring of blood glucose in diabetes treatment in a major test content. Portable blood glucose sensor (referred to as blood glucose meters) is an essential tool of Blood Sugar Testing.

At present, the market accu chek lancets  at least 20 kinds of models. Despite all the different accu chek lancets manufacturers and different models, they share the following characteristics: detection of capillary blood, and detection principle is similar to using dipstick testing, in order to dry the main power, light weight, small size, easy to carry, instrument calibration simple procedure, test results were affected by many factors and so on.

  1. Improper operation: Accu chek lancets test results the most important reason is the large variation of the user’s improper operation, such as the drop of blood the size of the drop of blood in the test strip on the location determination process does not meet the requirements.
  2. Hematocrit: Anemia or polycythemia can affect blood glucose meter test results. Anemia so that self-blood glucose test results than the actual value is high; polycythemia is the value of its measured value is lower than the actual. Every change in hematocrit is usually 10% of the measured values of different blood glucose meters can produce 4% ~ 30% of the impact.
  3. Blood Glucose Test Strip question: More than shelf-life or keeping improper also affects the test results. It affects the blood glucose meter accuracy and precision of the factors that self-monitoring of blood glucose effectiveness it will depend on the accuracy and precision of blood glucose meters. Accuracy of test results refers to the closeness of the real value; accuracy refers to the testing repeatability. Generally strictly controlled operating conditions and steps of the circumstances, the blood glucose meter accuracy and precision to achieve the standards (generally refers to the coefficient of variation 2% ~ 5%). However, if the following conditions exist, blood glucose meter accuracy and precision will be affected.

In addition to the patient’s mood, ambient temperature and humidity, hypotension, hypoxia, and blood triglyceride levels and other factors will affect the accu chek lancets  test results. In the former two alternative cases, the user’s operative technique becomes particularly important. Medical workers and vendors on behalf of blood glucose meters have the responsibility of the users of technical training.

How to determine the accuracy and precision of blood glucose meters?

Given the current models on the market blood glucose meters wide variety, the larger the variation between the test results, it can only be used for blood glucose monitoring cannot be used for diagnosis and screening of diabetes.

United States Institute of Clinical Biochemistry (NACB) and the American Diabetes Association (ADA) recommended the use of portable blood glucose meter blood glucose in patients must be regularly monitored blood glucose results and the results of the inspection department of the hospital as control to assess the value of their detection accuracy. With the laboratory results for blood glucose control should pay attention to: to do glucose tolerance or postprandial blood glucose test, the blood glucose meters blood glucose measured was significantly higher than hospital laboratories biochemical analyzer measured blood glucose value (an average of 1.7 cents Mount / l ), but no significant difference between fasting (a difference of only 0.1 cents Mount / l).
