ABG stands for what?

• A. Atrial Blood Gas
• B. Abnormal Gas
• C. Arterial Biogas
• D. Arterial Blood Gas

Answer: (D)

ABG stands for arterial blood gas. This test uses arterial blood to measure oxygenation and acid-base status, giving pH, PaO2, PaCO2, and bicarbonate levels. These values show how well the lungs are exchanging gases and how the body's acid-base balance is functioning, which helps diagnose respiratory or metabolic disorders and guide treatment. The other phrases aren’t standard terms for a lab test—for example, “atrial blood gas” would imply sampling from the heart, which isn’t routine, and terms like “abnormal gas” or “arterial biogas” aren’t used in clinical practice.
