SPECIMEN COLLECTION
Specimen type: 

Whole Blood


Preferred collection container: 
Specimen required: 

1 mL whole blood; minimum 0.4 mL.


Special notes: 

Expel excess air from syringe. Mix well immediately after collection. Due to sample instability, this test may only be collected and analyzed at a performing laboratory site (see below).

Test includes: 

Oxygen saturation.


Methodology: 
Optical
Synonyms: 

OXYGEN SATURATION ARTERIAL, OS2SAT, O2 SAT


Clinical significance: 

Oxygen saturation (or hemoglobin oxygen saturation) is a percentage of the volume of oxygen carried to the maximum volume that can be carried by hemoglobin for a whole blood specimen. It is useful for evaluating the amount of oxygen actually available for tissue perfusion and can be used to determine the effectiveness of oxygen therapy.
