Arterial Blood Gases (ABG) Test Price, Preparation, What does it detect - Complete Guide

An arterial blood gas (ABG) test measures how well your lungs supply oxygen to your body while simultaneously eliminating carbon dioxide from your body. Additionally, this blood test gives essential data regarding your body’s acid-base equilibrium. Unlike regular tests conducted on blood drawn directly from your veins, samples for this particular blood test are drawn from an artery, generally at the wrist area. The price of Arterial Blood Gases is between INR 1500 to INR 2100.

What is an Arterial Blood Gas Test?

An Arterial Blood Gas test measures several important components of blood, particularly:

• Partial pressure of oxygen
• Partial pressure of carbon dioxide
• Blood pH
• Bicarbonate
• Oxygen saturation

These values together are helpful for assessing your oxygenation and ventilation, as well as your acid-base status.

Your lungs and kidneys work constantly to keep the right balance between all sorts of things going on in your system including oxygen, carbon dioxide, acids, and bases.

When there's a problem somewhere along the line whether that involves how you're breathing, how stuff gets around (circulation), how much stuff gets made (metabolism), or even if something's wrong with your kidneys it throws off that balance. And an ABG test will be able to catch some of those problems.

Why is an ABG Test done?

Your doctor might recommend getting your ABG done if you have certain health problems that require more details about how well you're breathing or your acid-base balance.

This diagnostic can come in handy for people with serious illnesses or difficulty breathing, including those suffering from:

• Severe asthma
• Chronic obstructive pulmonary disease
• Pneumonia
• Respiratory failure
• Severe infections
• Heart-related conditions
• Metabolic disorders
• Kidney problems
• Unexplained changes in consciousness
• Difficulty breathing or shortness of breath

What does an ABG Test measure?

It measures various things. These are

• Blood pH
• PaO₂
• PaCO₂
• Bicarbonate
• Oxygen Saturation

How is the ABG sample collected?

Generally, an ABG sample will be taken from an artery (most often from the radial artery in your wrist).

The healthcare professional will clean this area before inserting a specialized syringe to take a little bit of your arterial blood. Because arteries have higher pressure than veins, taking an ABG may be just a little bit less comfortable than a regular blood test. You may feel some discomfort such as pain, pressure, or even stinging during this process. However, after you’ve provided your sample, the provider should apply pressure to the location to decrease your chances of having a bleed or a bruise. Then, they’ll run it through their blood gas analyzer appropriately.

Does an ABG Test require fasting?

Fasting isn’t usually specified for this kind of examination. If your physician/health care provider gives you some particular directions then it’s better to stick with them precisely. In case patients are using supplements of oxygen they need to mention that to the concerned health care professionals as well because usage of oxygen affects results of ABG significantly.

Is an ABG Test painful?

You may experience some discomfort when having an arterial blood gas (ABG) test done as your blood will be drawn directly from an artery instead of a vein. You’ll probably feel different levels of discomfort depending on how sensitive you are.

As mentioned earlier, this whole process is pretty quick! Applying firm pressure to where the blood was drawn will help prevent prolonged bleeding and bruising after this is complete. It’s also important that if you’re currently taking blood-thinning medications or have some kind of bleeding disorder that you let your healthcare professional know prior to doing this.

How to understand ABG results?

Doctors usually don’t look just at one value when they interpret ABG results. They look at your pH, PaCO2, bicarbonate level, PaO2, oxygen saturation, as well as your symptoms and medical history.

If you have an abnormal pH that goes along with an abnormal PaCO2 level, this might point toward a respiratory issue. Changes in the levels of bicarbonate might show up if there’s a metabolic cause.

With these values, the doctor can also figure out whether an abnormal result seems to stem mainly from the lungs, metabolism, or both. Remember, your reference range could change according to various things including which lab did the test (and their specific techniques), your age, medical conditions you have, etc.

This means you shouldn't attempt to interpret your ABG yourself using numbers you find online but instead seek guidance from a qualified health care pro.

What can affect ABG results?

Several factors can influence arterial blood gas measurements. These may include:

• Oxygen therapy
• Breathing pattern
• Lung disease
• Recent physical activity
• Certain medications
• Metabolic conditions
• Kidney function
• The patient's overall medical condition

What happens after the Test?

Most of you will be able to get back into your usual activities straight away after we’ve collected your blood but if you have any concerns please talk this through with our nurse before leaving.

Mild soreness and bruising around the area where the needle was inserted is common – applying pressure to the puncture site as soon as possible post-test is really important for preventing complications such as prolonged/heavy bleeding from the puncture site. You should contact us immediately if this does happen, or the site becomes significantly more painful/swollen than expected.

What is the difference between ABG Test and Pulse Oximetry?

Pulse oximetry is a technique that measures oxygen saturation using a device attached to the patient’s finger. It is a very useful tool for regular monitoring but has limited output as compared to arterial blood gas.

The detailed analysis provided by an arterial blood gas includes values for oxygen levels, carbon dioxide levels, and acid–base status. Hence, the doctors may choose to apply it if they need more detailed information.

Who may need an ABG Test?

An ABG may be helpful when the patient shows severe respiratory symptoms or has significant medical problems. The test may be requested by doctors when the gas exchange by the lungs or the acid-base balance needs to be evaluated.

The test may also be repeated throughout treatment to monitor the improvement of the patient's condition or to adjust the course of treatment if necessary.

Final Thoughts

The arterial blood gas test gives important feedback regarding how successfully the lungs carry out gas exchange with the blood and how effectively the body regulates its acid-base status. Although the procedure requires withdrawing blood from an artery and may cause some discomfort, the results obtained from the tests can be very helpful when assessing the state of lungs or overall metabolism requiring thorough examination.

In case your physician has prescribed the ABG test, it is necessary to follow the guidelines on how the test should be performed properly and share all necessary information on medication use, oxygen therapy, and current health condition.

At our imaging clinic, we focus on simplifying diagnostic tests and making them enjoyable for patients. Please contact our medical team or your doctor if you have any questions about the test or how to get ready for it.
