| Title | A Quantitative LC-MS Method to Determine Lutein Levels in Whole Human Blood Using Dried Blood Spot Analysis (DBS) |
| Summary | It is believed that lutein keeps eyes safe from oxidative stress and the highenergy photons of blue light. Further, studies have shown that an increase in macula pigmentation, such as lutein, may decrease the risk for disease such as macular degeneration (AMD). There’s also evidence to suggest that consumption of lutein and zeaxanthin lowers the risk of cataract development. An additional benefit of consuming lutein and zeaxanthin is the improvement of visual performance and decrease in light sensitivity (glare). In the work presented here, we have used dried blood spot (DBS) technology in conjunction with addition of an anti-oxidant that is prespotted on the DBS paper in order to stabilize the analyte and thereby preventing oxidation and degradation. Using this approach has led to reliable sensitivity and quantitation down to 10 ppb. |
