What is it used for?
An ABG test is used to:
- Check your acid-base balance
- Diagnose lung and breathing problems
- Identify kidney disorders
It also helps to monitor the effectiveness of treatment for breathing disorders, kidney disease, or other conditions affecting acid-base balance.
Why is the Arterial Blood Gas (ABG) test performed?
An Arterial Blood Gas (ABG) test may be needed for several reasons:
- If you have symptoms indicating an acid-base imbalance, such as rapid or deep breathing, nausea, vomiting, irregular heartbeat, confusion, fatigue, or muscle cramps.
- If you're being treated for lung diseases like asthma, COPD, cystic fibrosis, or conditions affecting breathing like myasthenia gravis.
- If you've experienced carbon monoxide poisoning, inhaled harmful substances, or sustained a head or neck injury affecting breathing.
- If you're receiving oxygen therapy in the hospital.

What do the ABG test results mean?
Arterial blood gas (ABG) test results typically show what was measured, your result, the normal range, and if the result is normal, high, or low. Abnormal ABG results may indicate low oxygen intake, insufficient carbon dioxide removal, or an imbalance in blood pH (either too acidic or basic).
These results can help diagnose conditions, and if they are abnormal, your healthcare provider may suggest further tests, such as additional blood or imaging tests, to confirm or rule out specific diagnoses.
Normal (ABG) Arterial Blood Gas Levels
-
The normal (ABG) Arterial Blood Gas level is pH range: 7.35-7.45.
-
Partial oxygen pressure (PaO2): 75 to 100 millimeters of mercury (mmHg).
-
Carbon dioxide partial pressure (PaCO2): 35 to 45 mmHg.
-
HCO3 (bicarbonate): 22–26 milliequivalents per liter (mEq/L).
For any abnormal value, you must consult a doctor.
