Abstract: A sample holder that enables mid-infrared spectroscopy of a test sample using mid-infrared light is disclosed. The sample holder includes an inlet port and a sample chamber that comprises a sample region and a capillary channel that fluidically couples the inlet port and the sample region. The capillary channel is characterized by a higher capillary force than the sample region. As a result, when the inlet port is put in contact with a liquid containing the test sample, the liquid is drawn into the sample region without the formation of bubbles that could obscure the optical analysis. In some embodiments, the inlet port is the free end of a draw tube having an outer diameter that is smaller than the minimum spacing between pain receptors at a draw site on a patient, which mitigates pain felt by the patient due to insertion of the draw tube at the draw site.
