hemoximetry

arterial blood oximetry

A clinical test that quantifies carboxyhaemoglobin (COHb) and methemoglobin, and calculates the content of O2 bound to haemoglobin (Hb). ABO is indicated in patients with anaemia or polycythaemia, for evaluating altered Hbs, O2 content of the blood, and to correlate the findings of arterial blood gas analysis.

Specimen
Arterial blood; because the analyte, carbon monoxide, is unstable, the specimen must be sent to the lab on ice and analysed as soon as possible.

Ref value
COHb < 1.5%; heavy smokers ≥ 5%.

hem·ox·im·e·try

(hēm'oks-im'ĕ-trē) Spectrophotometric analysis of blood for determination of the saturation of oxyhemoglobin and of dyshemoglobins (e.g., carboxyhemoglobin, methemoglobin).
Synonym(s): haemoximetry.
