Abstract:
1. A method of optically analyzing a fluid sample comprising: placing a sample-side surface of an optical format against a skin surface, the optical format including an optical communication path formed by an input light guide coupled with an input reflector, an output light guide coupled with an output reflector, and a sample cavity disposed between the input reflector and the output reflector, the optical communication path being continuous and closed between a first end of the input light guide and the input reflector and being continuous and closed between a first end of the output light guide and the output reflector; puncturing the skin surface with a lancet in communication with the sample cavity to obtain the fluid sample; collecting the fluid sample in the sample cavity; interacting the fluid sample with a reagent; directing light entering the input light guide through the sample cavity; detecting light which has passed through the sample cavity; and optically analyzing the fluid sample using the detected light.
