A method and system is provided that measures plasma protein levels of whole blood while a plasma donor is connected to an apheresis machine. A refractometer associated with the apheresis machine is capable of receiving a portion of a disposable tubing set including an integrated cuvette and prism. The integrated cuvette of the disposable tubing set can be inserted into a receiving space of the refractometer associated with the apheresis machine such that the light source and the sensor are oriented relative to the prism and a sensing surface of the integrated cuvette in a precise alignment. Calibration of the refractometer is made using anticoagulant pumped through the disposable tubing set including the integrated cuvette and prism. Based on a light intensity associated with this calibration, whole blood is then measured to determine plasma protein levels and donor eligibility.
