1. A system for measuring the concentration of at least one cell-free hemoglobin derivative in a sample containing hemoglobin derivatives contained within erythrocytes, the system comprising:

  • a light source configured to emit light;

    a sample block configured to allow the light to pass through the sample wherein, a first portion of the light, having a wavelength of about 390-460 nm, is absorbed by the cell-free hemoglobin derivatives and a second portion is absorbed by the hemoglobin derivatives contained within erythrocytes;

    at least one absorption detector configured to detect the light absorption within a wavelength range of about 390-460 nm that is absorbed by the sample; and

    a processor configured to compare the change in absorption of the light by the sample at least at two wavelengths and thereby determine the concentration of the cell-free hemoglobin derivatives.
