Claim Text:
1. A multiple layer test cartridge comprising: an input opening to receive a sample containing cells; an input channel coupled to the input opening to receive the sample from the input opening; a first lysing channel structure coupled to the input channel and adapted to receive the sample from the input channel, the first lysing channel structure having two side channels coupled to and extending away from an input channel and adapted such that the sample in the input channel is split between the two side channels, the first lysing channel structure having a backbone channel orthogonally coupled to the two side channels and adapted to receive and recombine the split sample; a second lysing channel structure having two side channels coupled to and extending away from the backbone channel of the first lysing channel structure and adapted such that the sample in the backbone of the first lysing channel structure is split between the two side channels of the second lysing channel structure, the second lysing channel structure having a backbone channel orthogonally coupled to the two side channels of the second lysing channel structure and adapted to receive and recombine the split sample; wherein the first lysing channel structure is disposed in a first polymer layer of the multiple layer test cartridge and the second lysing channel structure is disposed in a second polymer layer of the multiple layer test cartridge different from the first polymer layer, wherein the first and second lysing channel structures are adapted to lyse the cells in the sample; and a test chamber coupled to the backbone channel of the second lysing channel structure and is adapted to receive the recombined sample from the backbone channel of the second lysing channel structure.
