This different form of hemoglobin, which gives blood a brownish color instead of red, most generally is due to a genetic defect, drugs, or food. The patient having this condition may have a bluish skin color. Choose a location to see hospital-reported price summaries. This page does not show national, sample, or aggregate pricing.
