Abstract
A test strip for detecting an ion of interest present in urine for a urine optical analysis device cartridge, includes a sample pad configured to receive a urine sample, a test pad including a probe made of a fluorophore conjugated with an ionophore, a backing pad on which the sample pad and the test pad are arranged. The backing pad is configured to transport the ions of interest across to the test strip from the sample pad towards the test pad. The backing pad is made of a porous plastic membrane.

A test strip for detecting an ion of interest present in urine for a urine optical analysis device cartridge, the test strip comprising:
- a sample pad configured to receive a urine sample,
- a test pad comprising a probe made of a fluorophore conjugated with an ionophore, a fluorescence emission intensity of the fluorophore increasing when an ion of interest is binding with the ionophore, and
- a backing pad on which the sample pad and the test pad are arranged, the backing pad being configured to transport the ions of interest across the test strip from the sample pad towards the test pad, the backing pad being made of a porous plastic membrane.
