Abstract: A diagnostic system is provided, which can include a sample tube having an input end and an output end, a microfluidic device, a heating member, and a reagent. The microfluidic device may include a port member configured to couple with the sample tube, a sample distribution member coupled with the port member and having a microfluidic network with microfluidic channels, reaction chambers fluidly coupled with the microfluidic channels, a top cover configured to receive the sample tube therein and having openings corresponding to the reaction chambers, and a bottom member configured to mate with the top cover to enclose the port member and the sample distribution member. The bottom member may include a bottom chamber for retaining a composition. The heating member may be placed in the bottom chamber, and the reagent in the reaction chambers may provide a colorimetric reading upon interaction with a target analyte in the sample.
