Arterial Blood Gas Analysis (ABG)

Blood

Biomarkers included in this panel:

A-a O2

In an Arterial Blood Gas (ABG) analysis, the term A-a O2 refers to the alveolar-arterial oxygen gradient. It measures the difference between the oxygen concentration in the alveoli of the lungs and the arterial system. Alveoli are tiny, balloon-

Base Excess

Base Excess (ECF) - Arterial

The Base Excess (ECF) - Arterial marker on Labcorp's Arterial Blood Gas (ABG) Panel quantifies the amount of acid or base required to restore a liter of arterial blood to a normal pH of 7.40 at a PaCO2 of 40 mmHg and a temperature of 37°C. Th

Bicarbonate

Carboxyhemoglobin - Arterial

Glucose - Arterial

The Glucose - Arterial marker on Labcorp's Arterial Blood Gas (ABG) Panel measures the concentration of glucose in arterial blood. Glucose is a primary energy source for the body's cells and is tightly regulated by hormones such as insulin an

HCO3-, Arterial

The HCO3- - Arterial marker on Labcorp's Arterial Blood Gas (ABG) Panel measures the concentration of bicarbonate ions (HCO3-) in the arterial blood. Bicarbonate plays a crucial role in maintaining the acid-base balance of the body, functioning a

PCO2

pCO2 - Arterial

The pCO2 - Arterial marker on Labcorp's Arterial Blood Gas (ABG) Panel measures the partial pressure of carbon dioxide (CO2) in arterial blood. pCO2 is an important indicator of lung function and the body’s ability to remove CO2, a byproduc
