Chronically high blood sugar levels in type 2 diabetes can damage tissues throughout the body, such as the nerves, eyes, or kidneys. These vascular complications are a leading cause of death for patients, and scientists have been working toward designing a noninvasive, simple means to detect them early on in the course of disease progression. Typically, clinicians rely on a series of separate tests—from urine screens and ultrasounds to eye examinations—to estimate the risk of developing complications. A blood test based on a biomarker associated with a range of such issues would save time for patients and be more convenient for clinicians.
In the latest development toward that goal, researchers have created a blood test that can predict the likelihood of a diabetes patient experiencing a vascular complication. The signals of present problems came from distinct patterns of epigenetic modifications known as hydroxymethylations on freely circulating ...
