Anemia affects 2 billion people worldwide, including >half of preschool children and pregnant women in developing countries and at least 30% of children and women in industrialized nations. Identifying a blood disorder may be as easy as running a blood sample from a finger prick under a smartphone. Point-of-care devices give the user fast, easy-to-understand results from a test performed outside of a lab, such as a blood glucose test or pregnancy test. The device is made with a 3D printer and designed to detect anemia for individuals who have limited access to health care, such as those living in developing countries.
“Anemia is a very prevalent condition in developing countries even though it is easily treated with iron supplements or vitamins and can be prevented with a healthy diet,” Plevniak said. “Often in these developing countries people will have much easier access to smartphones than they will to doctors and trained medical professionals.”
The device consists of 3D printed clear plastic slides containing microfluidics that attach to a smartphone. The user adds a drop of their blood to a slide, which is used for a color scale-based test. The test results are produced in less than 60s and can be read using a smartphone, Plevniak said.
The researchers are developing a companion app with Steve Warren, associate professor in electrical and computer engineering at Kansas State University, that could manage data from the blood sample and even send the results to a doctor. Plevniak and He recently received approval to begin receiving and testing patient samples from the University of Kansas Medical Center. This will help researchers optimize the device for diagnosing different levels of anemia in human blood.
