1) WHAT IS GLUCOMETER ACCURACY?
The U.S. Food and Drug Administration (FDA) released its new recommendations on blood glucose meters saying that new meters need to be more accurate. These new accuracy standards mean that glucose meter values should be within 15 percent of the lab measurement 95 percent of the time and within 20 percent of the lab measurement 99 percent of the time.
2) IS THE GLUCOMETER AND LAB RESULTS SAME ?
All blood glucose meters use whole blood to measure glucose. Whole blood is simply a blood sample that contains the red blood cells. In a lab glucose test, only the plasma portion of the blood is used to measure glucose levels; the red blood cells are removed. Whole blood glucose test results are approximately 12 percent lower than the lab plasma results.
3) HOW CAN WE CHECK THE ACCURACY OF OUR GLUCOMETER?
The best way to measure the accuracy of your meter is to take it with you and check your blood with it immediately after you have a lab glucose test. Keep your glucometer ready while the phlebotomist /nurse is drawing your blood. Once the blood has been drawn for your lab test, ask the phlebotomist to drop some blood into your glucometer strip to get the result , alternately, you can prick your finger and perform a test with your meter soon after giving blood sample. For the best results, request that the lab processes your blood sample within 30 minutes of drawing your blood.
4) WHICH IS THE MOST ACCURATE GLUCOMETER IN THE WORLD?
According to the ,The Diabetes Technology Society (DTS) , which in the year 2017 revealed long-awaited results from its Blood Glucose Monitor System (BGMS) Surveillance Program. The rigorous study tested the accuracy of 18 popular blood glucose meters (BGM) used in the US. These FDA-cleared meters were purchased through retail outlets and tested rigorously at three study sites in over 1,000 people (including 840 people with diabetes). The results were troubling: only six out of the 18 devices met the DTS passing standard for meter accuracy – within 15% or 15 mg/dl of the laboratory value in over 95% of trials.
The devices that passed were:
1. Contour Next from Ascensia (formerly Bayer) – 100%
2. Accu-Chek Aviva Plus from Roche – 98%
3.Walmart ReliOn Confirm (Micro) from Arkray – 97%
4.CVS Advanced from Agamatrix – 97%
5. Free Style Lite from Abbott – 96%
6. Accu-Chek Smart View from Roche – 95%
5) WHICH IS THE MOST ACCURATE GLUCOMETER IN INDIA?
There is no such study done in India. When I searched about the brands available in India, thankfully i got an old study published in 2012. The chart below is from System Accuracy Evaluation of 43 Blood Glucose Monitoring Systems for Self-Monitoring of Blood Glucose according to DIN EN ISO 15197 by Dr. Guido Freckmann and others published in Journal of Diabetes Science and Technology, Volume 6, Issue 5, September 2012.Between 2009 and 2011, over a hundred people were recruited to test each of the meters listed below. The test strips were taken from at least seven different vials of one manufacturing lot. Over at least ten days, the patients tested their blood sugar with the meter and then a second sample was taken for analysis in a lab. open the chart here: https://www.diabetesdaily.com/blog/2013/07/blood-glucose-meter-accuracy-comparison-chart/
