A typical blood gas analysis costs around$400-$1200. Also known as an arterial blood gas test, a blood gas analysis usually measures the amount of oxygen and carbon dioxide in the blood, and it can also be used to determine the blood’s pH and acidity. Blood gas analysis can help doctors determine how well a patient’s lungs and kidneys are functioning, and is commonly used clinically to determine the internal environment of patients with acute or chronic illnesses. If there is an imbalance of oxygen, carbon dioxide, or PH, symptoms of shortness of breath, difficulty breathing, nausea, or impaired consciousness may occur. Blood gas analysis requires only a small sample of arterial blood, making this test relatively low risk. The average price of a blood gas analysis is usually around$400-$1200, but there may be some variation in charges due to differences in the manufacturers and cost prices of the instruments used in each hospital, but the price will usually be within this range.
