The 6 tests in this panel
What each one measures and the range labs usually print for adults. Ranges differ a little between labs, so the range on your own report is the one your result is judged against.
Arterial Blood pH
How acidic or basic your arterial blood is. The body holds it in a very narrow range, so small shifts matter.
- Adults
- 7.35–7.45 pH
Arterial pCO2
How much carbon dioxide is dissolved in your arterial blood. It shows how well your breathing clears this waste gas.
- Adults
- 35–45 mmHg
Arterial pO2
How much oxygen is dissolved in your arterial blood. It shows how well your lungs move oxygen into your blood.
- Adults
- 75–100 mmHg
- 75+
- 68 and above mmHg
Bicarbonate (HCO3-), Blood Gas
The bicarbonate your blood gas analyzer calculates from pH and pCO2. It shows the kidney-controlled side of acid-base balance.
- Adults
- 22–26 mmol/L
Base Excess (Base Deficit)
A calculated number showing extra acid or base in your blood, apart from breathing. A negative value is a base deficit.
- Adults
- -2–2 mmol/L
Oxygen Saturation, Arterial (SaO2)
How much of the hemoglobin in your arterial blood is carrying oxygen, measured directly from a blood sample. Finger pulse oximeters estimate this same number.
- Adults
- 95–100 %
