1. A fluid test apparatus comprising:
a housing;
a fluid test cartridge that is accommodated in the housing, the fluid test cartridge including an array of chambers configured to accommodate a fluid sample and a drying reagent;
a light emitter configured to emit light towards the array of chambers;
a light sensor configured to receive the light incident on the array of chambers and to detect an optical property of a first material included in the fluid sample based on the received light; and
a processor capable of determining a concentration of the first material based on the optical property detected by the light sensor,
wherein the drying reagent includes a non-metallic particle bound to a second material that specifically binds to the first material,
wherein the non-metallic particle is a nano-sized particle, and the nano-sized particle is at least one element selected from the group consisting of a carbon nanoparticle, a ceramic nanoparticle, and a polymeric nanoparticle, and
wherein the non-metallic particle absorbs an entire wavelength of visible light,
wherein the array of chambers comprises a first chamber which accommodates a first drying reagent, and a second chamber which accommodates a second drying reagent, and
wherein the first drying reagent comprises a first amount of an internal standard material included in the fluid sample and the second drying reagent comprises a second amount of the internal standard material included in the fluid sample,
wherein a first concentration of the first amount of the internal standard material, and a second concentration of the second amount of the internal standard material are preset, and the preset concentrations are mapped to identification information associated with the fluid test cartridge,
wherein the second material of the first drying reagent is different from the second material of the second drying reagent such that the first drying reagent measures a first concentration of the first material, and the second drying reagent measures a second concentration of the first material different from the first concentration, and
wherein the first material is antigens, and the second material is antibodies.
