Abstract
A system for testing for an analyte includes a test strip. The test strip includes a test strip detection conductor. The test strip includes a first flow path, the first flow path including a heating area, the test strip detection conductor in the heating area, the test strip detection conductor configured to be activated to heat a sample in the heating area.
Claims15
A system for testing for an analyte, the system comprising:
- a test strip including:
- a test strip detection conductor, the test strip detection conductor configured and arranged to provide a signal indicating a heating area has been filled when a first electrical contact and a second electrical contact are powered by a meter;
- a first flow path, the first flow path including the heating area, the test strip detection conductor in the heating area, the test strip detection conductor configured to be activated to heat a sample in the heating area when the second electrical contact and a third electrical contact are powered by the meter;
- wherein test strip further includes an e-gate, the e-gate in the first flow path, the e-gate separating the heating area from a detection area of the first flow path;
- a second flow path;
- an application port in communication with the first flow path and the second flow path, such that both flow paths may receive the sample, wherein the first flow path has a u-shape, such that the first flow path wraps around the test strip, the e-gate at a base point of the u-shape.
