The Arterial Blood Gas (ABG) Test is a medical test that measures the levels of oxygen and carbon dioxide in the blood, as well as blood pH. It provides critical information about the efficiency of lung function and the body's acid-base balance.
ABG testing is crucial for assessing respiratory function and acid-base balance in patients with respiratory or metabolic disorders.
Results guide clinical decisions for oxygen therapy, ventilation, and acid-base correction.
Test Parameters
1 - Oxygen (O2) Level
Measures the amount of oxygen dissolved in arterial blood.
2 - Carbon Dioxide (CO2) Level
Measures the amount of carbon dioxide dissolved in arterial blood.
3 - Blood pH
Measures the acidity or alkalinity of the blood.
Sample Collection
Arterial blood is drawn from an artery, often from the wrist (radial artery) or groin (femoral artery).
Collection Method : Arterial Blood Collection
Turn Around Time : Quick results are essential for immediate clinical decision-making.
Preparation
No specific preparation is required for the ABG Test.
This Test is Used For
Assessment of oxygen and carbon dioxide levels, acid-base balance in arterial blood
Risks
Since an ABG test involves a small sample of arterial blood, it is considered a low-risk procedure.
Inform your healthcare provider about existing medical conditions that may affect bleeding tendencies.
Disclose any use of over-the-counter or prescription medications, especially blood thinners, that may impact bleeding.
Possible side effects associated with the ABG test include:
Effect : Bleeding or bruising at the puncture site
Management : Apply pressure and a bandage to the puncture site. Report excessive bleeding to your healthcare provider.
Effect : Feeling faint
Management : Inform the healthcare provider if you experience dizziness or faintness during or after the test. Rest and hydrate as needed.
Effect : Blood accumulating under the skin
Management : Monitor for signs of hematoma. Report any significant swelling or discoloration to your healthcare provider.
Effect : Infection at the puncture site
Management : Keep the puncture site clean and watch for signs of infection such as redness, swelling, or discharge. Report any concerns to your healthcare provider.
