+<br>Finger-prick tests to monitor blood glucose levels can be the bane of a diabetic's life. In a move that could put an end to such tests in the future, researchers at Princeton University have developed a non-invasive way to test blood glucose levels using a laser. Like a number of other blood glucose measuring research efforts we've seen in recent years, such as carbon nanotube "tattoos" and biochips that measure glucose in saliva, the Princeton team's method doesn't require direct analysis of a blood sample. Instead, the new approach detects the level of blood sugar by directing a specialized laser at a person's palm and measuring the amount of absorption by the sugar molecules in the person's body. Rather than the person's blood, the laser targets dermal interstitial fluid, which has a strong correlation with blood sugar. Instead of near-infrared light, which is used by many medical devices, the Princeton team's method uses mid-infrared light. This is because although near infrared light is not blocked by water, making it suitable for use in the human body,  [GlycoMode](http://pourboy.wiki/index.php/User:TUEHannelore) it [interacts](https://www.trainingzone.co.uk/search?search_api_views_fulltext=interacts) with a number of acids and chemicals in the skin, making it unsuitable for detecting blood sugar.<br>
+
+<br>However, the use of mid-infrared light presents its own problems - it is difficult to harness with standard lasers and requires relatively high power and stability to penetrate the skin and scatter off bodily fluid. The researchers found the answer in the form of a new type of device particularly capable of producing mid-infrared light called a quantum cascade laser. Quantum cascade lasers boast the ability to produce one of a number of frequencies by passing electrons through a "cascade" of semiconductor layers. Recent developments have also provided increased power and stability, allowing the researchers to produce mid-infrared light with the properties required to penetrate the skin. In testing the approach the researchers measured the blood sugar of three healthy subjects before and after eating 20 jellybeans and compared the results to measurements taken with a finger-prick test. These measurements were [conducted repeatedly](https://www.medcheck-up.com/?s=conducted%20repeatedly) over a period of several weeks. Although the laser measurement readings produced average errors larger than the standard blood sugar monitors, the researchers said they remained within the clinical requirement for accuracy. Glucose monitors need to produce a reading within 20 percent of the patient's actual level and the early version of the new system met that standard with an accuracy of 84 percent.

However, they have since solved the cooling problem, allowing the laser to work at room temperature,  [GlycoMode](https://www.curry-pot.com/uncategorized/glyco-mode-blood-sugar-a-comprehensive-overview/) and will now look to shrinking the device.<br>

+<br>Healthy kidneys maintain the blood creatinine within a normal range. However, as kidney function declines, the kidneys may be unable to clear the creatinine level in the blood. Abnormally high levels of creatinine could indicate potential kidney malfunction or failure. For this reason, the doctors conduct a creatinine test (along with other tests) to determine how well your kidneys perform. Any condition that affects the function of the kidneys is likely to elevate the creatinine level in the blood. It is essential to work with your nephrologist to develop a treatment plan to address any medical issues that might be implicating your kidney function. In this article, we will look at the definition of creatinine, the test to determine the creatinine levels in the blood, ways to lower creatinine levels, and myths about lowering creatinine. Creatinine is a waste product produced mainly by muscle activities from the breakdown of the compound called creatine. Creatine is a metabolite from creatine phosphate from muscle and protein metabolism, which the body uses to supply energy to the muscles.<br>

+<br>As the muscles use energy, the tissue that comprises the muscles break down naturally, releasing the creatinine into the bloodstream. Creatinine can build up in the blood from a high protein intake, intense workout, medication or supplement dosage, or if a person has a kidney problem. Healthy kidneys filter creatinine from the blood and excrete it from the body through urine. However, impaired kidneys couldn’t filter creatinine and other waste materials properly from the body, thereby causing waste buildup. Doctors typically use a creatinine test to determine kidney function. However, checking the presence of creatinine alone in your blood isn’t the best way to evaluate your kidney health since your creatinine level is dependent on your age, race, gender, and body size. The best way to determine your kidney function is through Glomerular Filtration Rate (GFR). GFR is a calculation of your creatinine level, age, gender, race, and weight. Your GFR number will help your doctor determine if you have kidney disease.<br>
+
+<br>If your GFR number is below 60 for three months you may have kidney disease. Moreover, you may have kidney disease if your GFR number is above 60 with signs of kidney damage (presence of protein in the urine). Creatinine levels can be determined through two types of tests: a blood test and a urine test. The blood test a.k.a. A healthcare specialist will draw blood from a vein in your arm during this test, then send the blood samples to a lab for further analysis. Serum creatinine levels will elevate as kidney function declines. In the case where your kidney function is very low, or your muscle mass is abnormal, a creatinine clearance test becomes necessary. Your doctor may likely request a random single 24-hour urine sample, which involves collecting your urine for 24 hours. Serum creatinine is measured by milligrams (mg) of creatinine per deciliter (dL) of the blood.<br>
