| name | Carboxyhemoglobin/Hemoglobin.total in Arterial blood by Pulse oximetry | ||
| 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] | ||

| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | ||
