can someone tell me the procedure is for a arterial blood test (ABG) and if so how does this test different?

Question

from carboxyhemoglobin test, is there a difference of the two test? and if so, how does the procedure, differ, thank you

what i am realy trying to find out is how does a doctor make a chioce between having a carboxyhemoglobin test are a arterial blood gas test? lets just say that a doctor ordred a carboxyhemoglobin test on a person in the paper work but when the test was done the person giving the test did a arterial blood gas test, i just wonder how this could happen, thank all of you that have given me such great answers

Answer 1

A carbon monoxide blood test measures the level of carboxyhemoglobin. Carbon monoxide (CO) is a colorless, odorless, poisonous gas that binds to the hemoglobin in red blood cells much more strongly than oxygen does. Hemoglobin that comes in contact with carbon monoxide is converted into carboxyhemoglobin.

This test is done when carbon monoxide poisoning is suspected, either because of a history of exposure to the gas or because of such symptoms as headache, dizziness, muscle weakness, nausea, problems with judgment, vision problems, and sleepiness. However, it is often difficult to tell the severity of the poisoning based on symptoms alone.

An arterial blood gas (ABG) test measures the levels of oxygen and carbon dioxide in the blood to determine how well your lungs are working. It evaluates the ability of your lungs to move oxygen into the blood and to remove carbon dioxide from the blood.

An ABG test uses blood drawn from an artery, where the oxygen and carbon dioxide levels can be measured before they enter body tissues and become changed.

An ABG measures:

1. Partial pressure of oxygen (PaO2).
2. Partial pressure of carbon dioxide (PaCO2).
3. pH.
4. Bicarbonate (HCO3).
5. Oxygen content (O2CT) and oxygen saturation (O2Sat) values.

An arterial blood gas (ABG) test is done to:

1. Evaluate severe breathing problems and lung diseases, such as asthma, cystic fibrosis, or chronic obstructive pulmonary disease. It may also be used to monitor treatment for problems that affect breathing.
2. Evaluate your need for extra oxygen or help with breathing (mechanical ventilation).
3. Qualify you for home oxygen use.
4. Measure the acid-base level in heart or kidney failure, uncontrolled diabetes, sleep disorders, a drug overdose, or a severe infection.
5. Detect exposure to carbon monoxide and other chemicals.

I hope this information is helpful for you.

Answer 2

ABG's don't measure carboxyhemoglobin. Only a test for that measures it. An ABG measures the Ph, oxygen content, carbon dioxide content, bicarb, o2 saturation, and ratio's of arterial blood. They can tell the doctor if you are in acidosis, (even diabetic) or alkalosis. The ABG can tell the doctor you are low on oxygen. So, hope that helps. Carboxyhemoglobin measures if you have carbon monoxide poisoning, as in faulty heaters.

Answer 3

ABG is Arterial Blood Gas test. It detects the concentration of oxygen and carbon-dioxide in the blood and also the pH (acidity) of the blood, which is very relevant in Acute heart failure, respiratory failure etc.
