Venous blood gas test

A venous blood gas test measures the levels of oxygen, carbon dioxide, pH, and other chemicals in your veins. It helps doctors assess how well your body is balancing acids and bases, and how effectively your organs are exchanging gases. Unlike arterial blood tests, which analyze blood from arteries, venous tests are less invasive and provide useful information about your overall metabolic state and circulation. Results can help diagnose conditions like infections, metabolic disorders, and respiratory issues, guiding appropriate treatment decisions.
