How does a refractometer measure total protein?
How does a refractometer measure total protein? Modern refractometers measure total protein (TP) by the refraction produced by the total dissolved solids in plasma and have been calibrated to subtract 2.0 g/dL of the expected non-protein solids in plasma. These non-protein solids include urea, triglycerides,cholesterol, and glucose. How do you record total protein?
