Claim:
1. A photonic system for testing a sample to determine a blood type, comprising: (1) a first photonic device for determining the blood type, comprising: a first sample waveguide having a first sample surface; and a first binding coating covering and in optical communication with at least a portion of the first sample surface, the first binding coating being configured to directly bind to a blood cell target moiety in the sample indicative of the blood type, wherein the blood cell target moiety is attached to a blood cell body selected from the group consisting of a blood cell, a blood cell membrane, a blood cell fragment, a microvesicle, a microparticle, and a blood cell-associated antigen, and wherein the first photonic device is configured such that light passed through the first sample waveguide has an evanescent field that extends a distance beyond the first sample waveguide sufficient to detect the bound blood cell target moiety; and (2) a second photonic device for determining blood type, comprising: a second sample waveguide having a second sample surface; and a second binding coating covering and being in optical communication with at least a portion of the second sample surface, the second binding coating comprising specifically defined antigens configured to bind to an antibody in the sample indicative of immunity to blood antigens, wherein the second photonic device is configured such that light passed through the second sample waveguide has an evanescent field that extends a distance beyond the second sample waveguide sufficient to detect the antibody indicative of immunity to blood antigens, wherein the first photonic device and the second photonic device are configured to simultaneously test the sample.
