Arterial blood gas test
Arterial Blood Gas Test
The Arterial Blood Gas Test (pronunciation: /ɑːrˈtɪərɪəl blʌd gæs tɛst/), often abbreviated as ABG, is a diagnostic procedure used to measure the levels of certain gases and other parameters in the blood.
Etymology
The term "Arterial Blood Gas Test" is derived from the method of the test, which involves taking a blood sample from an artery to measure the gases present in the blood.
Procedure
The ABG test is typically performed by a healthcare professional who will draw a small amount of blood from an artery. The most common site for the blood draw is the radial artery in the wrist, but other sites can also be used. The blood sample is then sent to a laboratory where it is analyzed for levels of oxygen (O2), carbon dioxide (CO2), and bicarbonate (HCO3-), as well as blood pH.
Interpretation
The results of an ABG test can provide valuable information about a patient's respiratory and metabolic status. Abnormal results may indicate a variety of conditions, such as respiratory acidosis, respiratory alkalosis, metabolic acidosis, or metabolic alkalosis.
