Arterial Blood Gas Test

An Arterial Blood Gas (ABG) test measures the levels of oxygen and carbon dioxide in your blood, as well as the acidity (pH). It's often performed by drawing blood from an artery, usually in the wrist. This test helps doctors assess how well your lungs are functioning and whether your body is getting enough oxygen and removing carbon dioxide effectively. The results can indicate respiratory issues, metabolic problems, or kidney function, guiding treatment decisions for various health conditions.
