摘要： Diagnostic systems, methods, and devices employing low-cost handheld components are disclosed herein. A diagnostic system can include a diagnostic device that is configured to perform one or more assays on a fluid sample, such as a whole blood sample, in one or more microfluidic channels or chambers. The diagnostic device can move the fluid sample into or through the one or more microfluidic channels or chambers without using any electrical power, for example, using manual actuation to generate a positive or negative pressure within the diagnostic device. The diagnostic device can have a connector for interfacing with a separate handheld unit that can provide power and data processing. For example, the separate handheld unit can be a smartphone or PDA, and the connector can interface with an existing input/output port of the unit to draw power and/or transmit data.
