Healthcare workers use diagnostic tools to detect and determine the severity of a disease, as well as plan treatment and track the patient's response. There aren't many diagnostic tests that are portable and easy to use, and the ones that are often don't have enough sensitivity to offer any information other than if a biomarker is there or not. The optimal quantitative diagnostic test is the enzyme-linked immunosorbent assay, or ELISA, which is sensitive enough to identify how many specific antigens (protein markers) are in a particular biological sample. But researchers at Duke University have used 3D inkjet printing to create a diagnostic tool that has the potential to be better than ELISA.
