  Managing blood lipid levels is important for the treatment and prevention of
diabetes, cardiovascular disease, and obesity. An easy-to-use, portable lipid
blood test will accelerate more frequent testing by patients and at-risk
populations. We used smartphone systems that are already familiar to many
people. Because smartphone systems can be carried around everywhere, blood can
be measured easily and frequently. We compared the results of lipid tests with
those of existing clinical diagnostic laboratory methods. We found that
smartphone-based point-of-care lipid blood tests are as accurate as
hospital-grade laboratory tests. Our system will be useful for those who need
to manage blood lipid levels to motivate them to track and control their
behavior.
