When it comes to diabetes care, it's important to test glucose levels in the body. However, researchers are trying to figure out ways to test these levels non-invasively.
Researchers from Purdue University suggest that sensors may be able to detect glucose in tears, saliva and urine, which could be a low-cost and less invasive way to conduct diabetic testing.
"It's an inherently non-invasive way to estimate glucose content in the body," said Jonathan Claussen, a former Purdue University doctoral student and now a research scientist at the U.S. Naval Research Laboratory. "Because it can detect glucose in the saliva and tears, it's a platform that might eventually help to eliminate or reduce the frequency of using pinpricks for diabetes testing. We are proving its functionality."
Claussen continues that the research is important, as previous studies have not been able to prove that urine, tears and saliva could show glucose levels. Instead, these studies focused on measuring glucose levels in the blood. The researchers also noted that this test may require less process to produce than current sensors.
