What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Oxyhemoglobin/Hemoglobin.total. It is commonly used with the system or sample type Bld.preductal.

When is it used?

  • Used in lab systems, EHRs, and clinical data exchange.
  • May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
  • Status: DEPRECATED
  • Method: Pulse oximetry

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

  • Deprecated Fractional oxyhemoglobin in Blood Preductal by Pulse oximetry
  • Oxyhemoglobin/Hemoglobin.total
  • The component for this term Oxyhemoglobin/hemoglobin.total =O2Hb/(Deoxy HB+ O2Hb+ COHb +MetHb) and such a measure requires a co-oximter. It is not possible with oximetry or pulse oximetry. We have depricated this term and likned it o the test that this term was meant to represent with with Oxygen Saturation = O2Hb/(O2Hb+DeoxyHb) as the component and with method = pulse oximetry.
