Why are plasma hemoglobin levels (Hemopure or Oxyglobin) measured?
Plasma hemoglobin levels are measured to determine the amount of HBOC present in the patient specimen. These levels are used to compare the patient HBOC concentration with that of the predetermined HBOC limit (see Step 2) for accurate results in laboratory assays. The hemolytic index provided by the instrument manufacturer may be used as a conservative estimate.
