Oxygen saturation
An estimate of how much of your hemoglobin is carrying oxygen, usually from a pulse oximeter on a finger.
What it measures
A pulse oximeter shines light through the skin and estimates oxygen saturation, written SpO2. It is not a blood gas drawn from an artery, but it is a useful everyday number. Cold fingers, dark nail polish, poor circulation, and movement can make the reading wander.
Why it is on the panel
It documents breathing and oxygen delivery at the time of the visit. People with asthma, lung disease, anemia, or a recent respiratory infection use it as a home checkpoint. On a screening panel it is a baseline.
How to read it
Sit still, warm the hand, and wait until the number settles. Compare it with how you feel. A low saturation with a low hemoglobin means there is both less hemoglobin and less oxygen loaded onto it.
When it runs higher
Readings of 99% or 100% are ordinary in healthy people at sea level. Supplemental oxygen is the setting where a very high reading is expected and intentional.
When it runs lower
For most healthy adults at sea level, a resting saturation of 95% or higher is the usual expectation. Readings that stay under 92%, or a sudden drop with shortness of breath, chest pain, or confusion, need urgent care. Altitude lowers the expected number.

How to use this page
This page explains what the measurement is for. It is educational. Your Healiam report includes the reference interval for your age and sex, and a clinician reads that result with your history, medicines, and the rest of the panel. Talk with a clinician before changing diet, supplements, or treatment because of a number on a report.
Oxygen level
Oxygen level is part of the full panel.
No referral or insurance required.
One preventive draw covers this measurement and the rest of the Healiam panel. CLIA-certified results come back in days.
