Test Blood Sugar Without Pricking Your Finger

Checking Your Blood Sugar--without Checking Your Blood

Checking Your Blood Sugar--without Checking Your Blood

As every patient with diabetes knows, pricking your finger to check your blood sugar is a dreaded daily ritual. Not only is it a painful reminder of the disease itself, it’s currently the only way to consistently and accurately monitor your blood sugar. It’s especially tough on children and leads to much anxiety--beyond having the condition itself. A “fingerstick”, as it is known by many healthcare professionals and patients alike--involves using a sharp lancet to puncture the skin of your fingertip, followed by placement of a drop of blood on a special instrument (glucometer) that can read your glucose level, usually in under a minute or so. Now it seems that a research group from the University of Leeds in England has tackled the problem of how to measure blood sugar noninvasively—without having to actually puncture the skin at all! The new technique, according to the researchers, is based on the interaction of ions in a special nano-engineered silica-type glass device which fluoresce in response to infrared light waves. Embedded in the special silica glass are ions which produce special infrared fluorescent light waves in response to light from certain laser wavelengths. The wavelength produced is related the level of the blood sugar in the blood vessels near the skin when a finger is placed onto a special glass device. And based on their research, it appears that the period of time that fluorescence occurs is related to the concentration of glucose in the superficial blood vessels or capillaries in the skin. In fact, according to a recent study from the Leeds Institute of Cardiovascular and Metabolic Medicine, the results from the device were comparable to results achieved using a standard glucometer with finger pricking. “This device if proven to be eff Continue reading >>

Monitoring Your Blood Sugar Level

Monitoring Your Blood Sugar Level

What tests can I use to check my blood sugar level? There are 2 blood tests that can help you manage your diabetes. One of these tests is called an A1C test, which reflects your blood sugar (or blood glucose) control over the past 2-3 months. Testing your A1C level every 3 months is the best way for you and your doctor to understand how well your blood sugar levels are controlled. Your A1C goal will be determined by your doctor, but it is generally less than 7%. The other test is called SMBG, or self-monitoring of blood glucose. Using a blood glucose monitor to do SMBG testing can help you improve control of your blood sugar levels. The results you get from an SMBG test can help you make appropriate adjustments to your medicine, diet and/or level of physical activity. Every person who has diabetes should have a blood glucose monitor (also called a home blood sugar meter, a glucometer, or a glucose meter) and know how to use it. Your doctor may prescribe a blood glucose monitor. The U.S. Food and Drug Administration (FDA) has approved meters that work without pricking your finger. But these meters cannot replace regular glucose meters. They are used to get additional readings between regular testing. What supplies do I need? You will need a glucose meter, alcohol pads, sterile finger lancets and sterile test strips. Check with your health insurance plan to see if they will pay for these supplies. How do I pick a glucose meter? Check with your health insurance plan to see if they will pay for your glucose meter. If so, your plan may only pay for a certain meter. If your insurance plan doesn’t pay for glucose meters, ask your doctor which meters he or she recommends. Shop around and compare costs. Consider what features are important to you. For example, some meters are Continue reading >>

Apple’s Needleless Blood Sugar Tracker Has An Uphill Battle In Front Of It

Apple’s Needleless Blood Sugar Tracker Has An Uphill Battle In Front Of It

Rumors are flying that Apple is developing some kind of wearable that would continuously track the user’s blood sugar without breaking their skin. For people with diabetes, this would be a huge improvement over the somewhat invasive or downright painful options they currently rely on. But experts warn that if the rumors are true, Apple will be facing a scientific and technological battlefield littered with decades of other companies’ failures. If Apple is chasing a needleless blood sugar monitor, it wouldn’t be that surprising. (Apple declined to comment.) After all, the market would be massive. About 30 million Americans have diabetes, a disease caused when there’s too much sugar, or glucose, in the blood. People with diabetes have to carefully titrate their food intake, or even inject the hormone insulin in order to keep their blood sugar from spiking or dropping to dangerous levels. So regularly measuring blood glucose is key. Right now, it’s also unpleasant. People with diabetes have to prick their fingers to draw blood, or wear a monitor that inserts a tiny tube beneath their skin to continuously measure glucose in the fluid between cells (the same fluid that spills out when you pop a blister). So a needleless device — preferably one that continuously monitors glucose levels and spits them out in real time — would be a huge upgrade. “That is the holy grail,” says Eric Topol, the director of the Scripps Translational Science Institute who also sits on the board of glucose monitor manufacturer Dexcom. And that’s why so many before Apple have made the attempt. Google tried to develop a contact lens to detect glucose in tears, but ever since pharmaceutical giant Novartis licensed the technology in 2014, the project’s gone quiet.

Fda Approves 1st Blood Sugar Monitor Without Finger Pricks

Fda Approves 1st Blood Sugar Monitor Without Finger Pricks

Federal regulators have approved the first continuous blood sugar monitor for diabetics that doesn't need backup finger prick tests. Current models require users to test a drop of blood twice daily to calibrate, or adjust, the monitor. The discomfort of finger sticks and the cost of testing supplies can discourage people from keeping close tabs on their blood sugar. Abbott's new FreeStyle Libre Flash Glucose Monitoring System uses a small sensor attached to the upper arm. Patients wave a reader device over it to see the current blood sugar level and changes over the past eight hours. The Food and Drug Administration approved the device Wednesday. Abbott isn't disclosing the price for the reader or the sensors, which should be available in pharmacies within months. Continue reading >>

A Diabetes Monitor That Spares The Fingers

A Diabetes Monitor That Spares The Fingers

For the past year and a half I’ve been buying a medical device from Italy that has improved my life immeasurably. It wasn’t easy: I roped in a good friend who had moved to Milan to buy the device and ship it to me because it wasn’t yet available in the States. And it was expensive: over $1,600 a year. But my black-market purchase helps me manage my Type 1 diabetes without the need to draw blood from my callused fingers 10-plus times a day to track my glucose level, a ritual that had been an unpleasant part of my life for decades. The FreeStyle Libre, made by Abbott, is a flash glucose sensor that allows people with diabetes to view our blood sugar every minute of the day without a single finger prick. While there are similar devices on the market — called continuous glucose monitors, or CGMs — the Libre is the least invasive one I’ve seen. It takes readings from a sensor under the skin but doesn’t require finger sticks for calibration, and is about the size of a quarter and as thick as two. And it’s helping me keep my diabetes under better control. There have been some challenges: The Milanese UPS store wanted a letter detailing exactly what was in the box. My credit card’s fraud department called (“Yes, the charge for $365 from Milan is mine”). So I was thrilled to learn that the Food and Drug Administration recently approved the sale of the Libre in the United States, a decision that may help some of the 29 million Americans with diabetes. The Libre I buy from Italy has a self-adhesive, waterproof white sensor that sticks to my arm for 14 days. It took some trial and error to get used to it. One sensor flipped off from over-aggressive toweling at the gym; another came loose after a backpack strap nicked it. Finally, rather than the spot on my out Continue reading >>

Israeli Device Banishes Finger-pricking For Sugar Levels In Diabetes Patients

Israeli Device Banishes Finger-pricking For Sugar Levels In Diabetes Patients

Diabetes patients know that one of the greatest challenges in managing the ailment is tracking their blood sugar, or glucose, levels. To do that the only option available today is through the use of standard glucose meters — devices that require multiple finger pricks each day, a painful process. For years, researchers have been trying to find a noninvasive, quicker and easier way to monitor blood glucose. Even the most advanced devices in use today, like needle sensors, which can track glucose continuously, need to be inserted under the skin every one to two weeks. Free Sign Up Now, Caesarea-based startup Cnoga Medical Ltd. says it has come up with a way to track blood glucose levels without pricking or pain. Its glucose meter, already approved for use in numerous countries worldwide, uses a camera to provide a diagnosis of blood glucose levels by observing the changing colors of the user’s finger. During a short training period, the device learns to correlate the user’s skin tone with previous glucose level readings. The technology got the green light on Monday from one of the world’s leading diabetes specialists, Prof. Andreas Pfützner, MD, PhD, who came to Israel to present the company with his findings after having tested the technology in two clinical studies in Germany. “The results were surprising,” he told The Times of Israel in a phone interview. Pfützner held two clinical trials at his institute to validate the performance of the technology, and in both studies he found that the medical device performed “with a surprising level of accuracy,” the same as that of needle sensors. “Cnoga achieved the same level of monitoring as the invasive devices,” he said. “I have not seen this before,” he said. “It is a wonderful device” and a Continue reading >>

The Fda Has Approved A Blood Sugar Monitor That Doesn’t Require A Finger Prick

The Fda Has Approved A Blood Sugar Monitor That Doesn’t Require A Finger Prick

Further proof the U.S. Food and Drug Administration has been warming up to modern technology — it has just approved the first continuous blood sugar monitor that doesn’t require the user to prick themselves over and over for a blood sample. Today, the FDA cleared Abbot’s FreeStyle Libre Flash Glucose Monitoring System, a device that uses a small sensor wire inserted under the skin to determine glucose levels in adult diabetics. Another wand-like device is then waved over the sensor to measure and give a readout of those glucose levels. This is a milestone move for the FDA as diabetes affects nearly 30 million people in the United States who currently have to test their blood sugar by pricking themselves several times throughout the day and every time they eat. However, the idea for a prickless blood sugar monitor isn’t new. Tech companies have increasingly shown an interest in the massive diabetics market over the past few years. Apple is rumored to be working on such a device and its CEO Tim Cook has even been spotted wearing a possible prototype that could connect to the Apple Watch. Other companies endeavor to build something similar, including Glucowise, which has a device still under development. However, it seems it’s not so easy to create a needleless blood sugar detector. Google tried to build a contact lens that could detect glucose but it seems the project has gone nowhere since drug company Novartis licensed the tech in 2014. Another FDA-approved device for glucose monitoring without the prick called the GlucoWatch was approved in the early 2000’s, but consumers found it cumbersome and it happened to cause a bad rash in some. But there’s new hope today that the Freestyle monitor has worked out all the kinks. The device is intended for those 18 a Continue reading >>

Most of the 30 million Americans with diabetes use standard glucose meters, which require multiple finger pricks each day and only show current sugar level. More-accurate continuous glucose monitoring devices are used by about 345,000 Americans. But most don't do the finger pricks to calibrate them and may get inaccurate readings, said Dr. Timothy Bailey, who helped test FreeStyle Libre. "We're able to lower blood sugar safely" with this technology, said Bailey, director of the Advanced Metabolic Care and Research Institute in California. He receives consulting fees from various diabetes device makers. Too-high blood sugar levels can damage organs and lead to heart attacks, strokes, blindness and amputations. Very low blood sugar can cause seizures, confusion and loss of consciousness. Abbott's device was approved for adults with Type 1 or Type 2 diabetes and should be available in pharmacies within months. The company, based near Chicago, did not disclose the price of the reader or the sensors. Abbott's system can't be used with an insulin pump, a device worn against the skin th Continue reading >>

The Fda Just Approved A Device That Can Monitor Blood Sugar Without Finger Pricks

The Fda Just Approved A Device That Can Monitor Blood Sugar Without Finger Pricks

Abbott's device continuously monitors blood sugar levels.Abbott The FDA on Wednesday approved a device that monitors blood sugar levels without needing to draw blood via a finger prick. The device, which is made by Abbott and called the "FreeStyle Libre Flash Glucose Monitoring System," continuously monitors a person's glucose level via a sensor that's stuck on the body. It's the first device of its kind that doesn't require users to calibrate the system with a traditional finger-prick blood draw twice a day. "This system allows people with diabetes to avoid the additional step of fingerstick calibration, which can sometimes be painful, but still provides necessary information for treating their diabetes—with a wave of the mobile reader," the FDA's Donald St. Pierre said in a news release. For people living with diabetes, checking blood sugar levels with a drop of blood from the finger is a common practice. Diabetes is a condition in which people have a hard time processing sugar, which can lead to complications if those levels get too high or drop too low. Continuous monitoring lets you see not only when blood sugar is too high or too low, but also whether it is rising or falling. According to a review of literature by the American Association of Clinical Endocrinologists, testing blood sugar more frequently tends to be related to better blood sugar control. Abbott's competitor Dexcom, which still requires the finger sticks for calibrating its device, was down 34% on the news Thursday. "The clear loser in the FDA’s decision is Dexcom," Jefferies analyst Raj Denhoy said in a note Wednesday. That's because on paper, Abbott's device looks better since it doesn't require finger pricks, has better accuracy, and is cheaper. "We believe we've got something here that's rev Continue reading >>

Test Your Glucose Level Without Drawing Blood

Test Your Glucose Level Without Drawing Blood

People with diabetes and impaired glucose tolerance are advised to spot-check their blood-glucose levels several times daily to reduce the risk of serious complications. That’s a lot of finger-pricking, considering that about 700 million people fall into one of those categories. The Israeli company Integrity Applications put more than a decade into developing GlucoTrack, described as the first truly noninvasive system for self-monitoring glucose levels. Instead of drawing blood, you clip the GlucoTrack sensor to your earlobe. A patented combination of ultrasonic, electromagnetic and thermal technologies works with a proprietary algorithm to measure physiological parameters correlated with glucose level. Results are displayed within about a minute on a USB-connected handheld control unit, which also stores and compares previous readings. The number is announced verbally, facilitating use by elderly and vision-impaired people with diabetes or pre-diabetes. Sales in parts of Europe, South America, Australia and New Zealand began in 2016, after the newest version of the device won regulatory approval in Europe and in South Korea. Integrity is soon beginning clinical trials of GlucoTrack Model DF-F in the United States required for US Food and Drug Administration (FDA) approval, and is working toward approval in China. The “DF” stands for David Freger, the late Israeli physicist who envisioned a novel noninvasive glucose monitor. His colleagues Avner Gal and David Malka helped him turn it into reality. “David passed away from diabetes complications at age 48 in 2004, and we called our device models DF to memorialize him,” Gal tells ISRAEL21c.

Device To Keep Tabs On Blood Sugar Levels Without Finger-pricking Available In Singapore

Device To Keep Tabs On Blood Sugar Levels Without Finger-pricking Available In Singapore

SINGAPORE: When Mr Kevin Lim was diagnosed with diabetes in June last year, the 40-year-old wanted to do all he could to improve his condition. The first step would be to start monitoring his blood glucose levels so he could get a better sense of the severity of his diabetes. With that, however, he faced the inevitable task of pricking his finger almost daily - or so he thought. Through some research, Mr Lim, who works in an innovation lab, discovered a flash glucose monitoring device online that he could buy and use at home that could do away with the need for pricking his fingers. Self-monitoring for diabetes patients typically involves pricking the finger for a drop of blood that has to be transferred onto a test strip and read with a small machine. The flash glucose monitoring device measures the glucose level of tissue fluid through a sensor about the size of an old Singapore 50-cent coin. The sensor is attached to the back of the upper arm by painless self-insertion and an adhesive pad. Readings are made by scanning the sensor with a separate machine. The sensor that can be worn for up to two weeks and holds eight hours of 15-minute glucose readings at any time is water-resistant. Mr Lim ordered it on eBay, but the device, that for a few years has been available in the US and Europe, landed in Singapore in May this year. Advertisement With the device, Mr Lim has been able to observe which foods cause his blood glucose level to spike, which activities help him to maintain a healthy blood sugar level, and whether the medication he was prescribed were effective. In diabetic patients, high blood glucose levels after a meal has been linked to heart disease. The monitoring being more discreet than finger-pricking is something Mr Lim appreciates. “It’s demoralising t Continue reading >>

Diabetes System Continuously Checks Glucose Without A Finger Prick

Diabetes System Continuously Checks Glucose Without A Finger Prick

Thanks to a system developed by Dexcom, a developer of technology for diabetes, diabetics won’t need to prick their fingers anymore to check their glucose levels. The Dexcom G5 is a glucose monitoring system that uses a sensor, a transmitter, and the user’s smartphone to continuously monitor the user’s glucose levels. “The Dexcom G5 Mobile system is the only continuous glucose monitor that the FDA has approved to replace finger stick blood glucose measurements when making diabetes treatment decisions,” says Jake Leach, senior vice president of research and development at Dexcom. A hair-like, stainless steel needle is inserted into the abdomen and releases the sensor, a flexible, metal wire with proprietary embedded membranes. After insertion, the needle is removed while the sensor is left behind. “These membranes are highly biocompatible and include glucose oxidase enzyme technology, which allows the sensor to accurately measure glucose” Leach says. "It undergoes testing to ensure biocompatibility." The coding also manages the amount of glucose that goes to the sensor enzyme, allowing consistency with the amount of glucose being transported. The sensor is connected to a thin, patch-like transmitter with two electrodes that use a 12-amp signal. As soon as the transmitter snaps with the sensor, it begins to function. The sensor comes out when the patch is removed. The transmitter is similar to a shell, designed with a polymer resin using a custom molding process. It was designed without a seal so it cannot be opened, which keeps it waterproof. Since the transmitter is not disposable, the batteries, two silver oxide coin cells, cannot be replaced. The transmitter, which runs on low power to ensure only its frequency is picked up, should be replaced after thre Continue reading >>
