Simple saliva test could spot early heart disease risk: Study

New Delhi: A simple saliva test could help identify the earliest warning signs of cardiovascular disease, according to a study.

Scientists have identified a link between high white blood cells in the saliva of healthy young adults and an early cardiovascular



disease warning sign.

They used a simple oral rinse to see if levels of white blood cells — an indicator of gum inflammation — in the saliva of healthy adults could be linked to warning signs for cardiovascular disease.
