Blood Gas Analysis is a medical test that measures the levels of oxygen, carbon dioxide, and acidity (pH) in the blood. It helps assess how well the lungs and kidneys are functioning and can indicate respiratory or metabolic issues. This test is often performed on arterial blood, which provides a more accurate reflection of oxygen levels in the body. The results of a Blood Gas Analysis can help healthcare providers diagnose conditions such as asthma, chronic obstructive pulmonary disease (COPD), and kidney disease. By understanding the balance of gases and pH, doctors can make informed decisions about treatment and management of these conditions.
