You can actually get the same information from the ABG and the VBG. The only difference is from where the information can be taken. The ABG blood sample is normally used in order to check the current metabolic environment, the oxygenation, and the ventilation status of the blood.

The VBG measures the level of acidity that can be found in the blood. These two may be a bit confusing and it should also be remembered that the venous blood is also going to be darker but you can get the different samples depending on what would need to be measured. For example, if there is a need to measure oxygen, the ABG will probably be the better option.
