Claim 13:
14. A method of analyzing a fluid sample, the method comprising:
moving a thin-film element between a first sensor and a second sensor in a direction substantially perpendicular to a vertical direction defined from the first sensor to the second sensor, wherein the thin-film element comprises:
a first layer for processing the fluid sample to generate a first component and a second component,
a second layer configured to be impermeable to the first component to allow the first component to be retained by the first layer and permeable to the second component to allow the second component to pass through the second layer, wherein the second layer comprises a first reflective surface and a second reflective surface, and
a third layer configured to retain the second component;

simultaneously generating a first optical signal by reflecting a first light modulated by the first component off of the first reflective surface and generating a second optical signal by reflecting a second light modulated by the second component off of the second reflective surface; and
simultaneously receiving the first optical signal by the first sensor and receiving the second optical signal by the second sensor.
