Researchers from the University of British Columbia (UBC) have introduced a new and simple test that can detect insulin levels and early signs of diabetes using only saliva — without the need for a blood sample.
According to a medical website, this test is painless, cheaper, and easier compared to current blood-based methods. The study involved 94 healthy participants who were asked to drink a medical shake after fasting. Their saliva samples were then taken at 30, 60, and 90-minute intervals.
Surprisingly, even some people with low body weight showed a sharp rise in insulin levels through saliva, indicating they could also be at risk of diabetes.
The study found that factors like waist size, age, gender, and BMI (Body Mass Index) were linked to insulin levels in saliva, with waist size being the strongest indicator.
Experts say this test could be helpful in the future not only for early diabetes detection but also for other chronic diseases like high blood pressure, heart issues, stroke, cancer, and obesity.
Currently, insulin is measured through blood tests, which are not difficult, but the saliva test offers a much easier and more affordable alternative.
Researchers believe more studies are needed before this test becomes widely available.
