Why are blood gas tests typically performed?

Blood gas tests are primarily conducted to assess the respiratory function and the acid-base balance within the body. This is crucial in diagnosing and managing conditions related to breathing problems and lung diseases, such as chronic obstructive pulmonary disease (COPD), pneumonia, or asthma, where oxygen and carbon dioxide levels in the blood may be significantly affected.

By measuring the levels of oxygen and carbon dioxide, as well as the pH of the blood, healthcare providers can gather important information about a patient's lung efficiency and overall metabolic status. This data is vital in making informed decisions regarding treatment options for respiratory conditions and analyzing how well the lungs are functioning in oxygenating the blood.

In contrast, blood clotting disorders, liver function analyses, and infections would require different tests and do not fall within the scope of what blood gas tests evaluate. Each of these other options targets different clinical concerns and would utilize specific laboratory tests designed for those purposes.
