Abstract
Some embodiments of the invention provide one sample holder that is suitable for collection and spectroscopic measurement of a blood sample. In some very specific embodiments, the sample holder is provided with an optical chamber that is specifically designed to spread blood into a thin film, thereby reducing the average attenuation of electromagnetic radiation (EMR) due to scattering of EMR by the red blood cells in a blood sample, without having to hemolyze the red blood cells. Also, the sample holder is designed so that air bubbles are easily pushed through the optical chamber and guided out of the sample holder through a vent. In some embodiments, the inlet of the sample holder can be reconfigured with adaptors to receive blood from for example, a pin prick or a syringe. Use of adaptors makes the housing simpler when considering the manufacturing process.
