LOINC description : Used to report the carboxyhemoglobin level as a percent of the total hemoglobin using
pulse oximetry. Note that conventional pulse oximeters are not used to measure carboxyhemoglobin
because they use two wavelengths of light that does not allow distinction between
carboxyhemoglobin, methemoglobin, and oxyhemoglobin. However, newer pulse oximeters
use multiple wavelengths (e.g., seven, eight or twelve) that allow separate measurement
of carboxyhemoglobin. [PMID: 21459480];
