A method and apparatus for measuring Tot-Hb in a sample are provided. The method comprises collecting absorbance measurements of a sample using a spectroscopic apparatus that comprises a first primary calibration algorithm for one of Oxy-Hb, "Oxy-Hb plus Deoxy-Hb", or "Total-Hb minus Met-Hb" and a second primary calibration algorithm for one or more than one of Met-Hb, Carboxy-Hb, or Sulf-Hb, or comprising a third primary calibration algorithm obtained by adding terms of the first primary calibration algorithm and the second primary calibration algorithm together. Followed by predicting either a first value for one of Oxy-Hb, "Oxy-Hb plus Deoxy-Hb," or "Total-Hb minus Met-Hb" and predicting second value for one or more than one of Met-Hb, Carboxy-Hb, or Sulf-Hb in the sample and add the first and second value together, or predicting a value for Total-Hb.
