To help the growing population of diabetics in Singapore better manage the disease, Diabetes Singapore will be giving away free Abbott FreeStyle Libre Sensors from Thursday (Sep 1). CNA Lifestyle looks at how accurate their readings are and whether you'll still need to hold on to your glucometer.
, diabetics know the finger-prick blood test all too well. They have to frequently prick their fingers for blood samples and apply the blood to a glucometer to test their blood sugar levels and assess their insulin requirements.
Still, the frequency of the finger-prick test can come up to once or twice a week, or four times a day, said Dr Ester Yeoh, a senior consultant endocrinologist at Khoo Teck Puat Hospital."It’s not just the number of finger pricks," she said."When testing needs to be done in the middle of the night to monitor for hypoglycaemia , it can be troublesome and annoying for patients and caregivers," she said.
"CGM, on the other hand, offers a constant flow of information in real time, enabling users and their caregivers to identify trends and patterns in their glucose levels," he said. “These readings can be a little different, in part, because they measure different fluids,” he explained, “but also because it takes time for glucose to move from the blood to the interstitium when the blood glucose is changing. It takes 10 to 15 minutes before those changes are seen in the interstitial fluid.”This is particularly so when the glucose levels are very high or very low, he said.
“After a few weeks, they are able to figure out what they need to do in order to improve their blood glucose control and thereafter, if they are able to maintain those changes in medication or lifestyle, they may be able to stop the glucose monitoring,” said Prof Tai.
