Abstract
Disclosed is a microfluidic cartridge that can perform highly accurate lab quality DNA tests and other amplification based tests at the point of care. The cartridge may have slanted channels that angle downward from the inlet well, where the sample is deposited, to the reaction well, where the sample will flow down to and initiate the reaction. In some examples, the cartridge may be fabricated from specific materials that enhance passive flow through the channels. Additionally, the reaction wells have an access port that allows ventilation to the reaction wells that enhances the flow of the sample from the inlet to the reaction well. The access ports allow convenient access for depositing the reaction mixture into the reaction wells after the cartridge is fabricated.
