Testing for nutritional deficiencies in blood can be invasive and expensive. A team led by Michigan Technological University explored what it takes to test tears instead.

Maryam Khaksari, a research specialist at the Chemical Advanced Resolution Methods (ChARM) Laboratory at Michigan Tech, is the lead author of a paper on the subject recently published in Experimental Eye Research.
"Our goal was to seek the viability of establishing measurable vitamin concentrations in tears for nutritional assessments,” Khaksari says. "Your body cannot manufacture vitamins, and vitamins reflect available food sources in your body. That's what makes them good indicators of nutritional health."
