    No one seems to be able to explain low carbon dioxide lab results....my impression is that they think it's immaterial. Does anyone else have thoughts on this?

    A carbon dioxide test measures the total amount of the three forms of carbon dioxide (bicarbonate, carbonic acid, and dissolved carbon dioxide) in your blood. Results are usually available in 1 to 2 days.

    Normal
    Carbon dioxide Adults: 23-29 millimoles per liter (mmol/L)

    Children: 20-28 mmol/L

    Babies: 13-22 mmol/L


    High values

    High values may be caused by:


    Diseases that decrease blood pH (respiratory acidosis), such as chronic obstructive pulmonary disease (COPD), emphysema, and pneumonia.
    Diseases that increase blood pH (metabolic alkalosis), such as Cushing's syndrome, Conn's syndrome, and alcoholism.
    Vomiting.

    Low values

    Low values may be caused by:

    Problems that increase blood pH (respiratory alkalosis), such as pneumonia, cirrhosis, liver failure, or hyperventilation.
    Problems that decrease blood pH (metabolic acidosis), such as uncontrolled diabetes, kidney or heart failure, aspirin overdose, shock, frequent diarrhea, dehydration, long-term (chronic) starvation, and swallowing antifreeze (ethylene glycol) or wood alcohol (methanol).
    What Affects the Test
    Reasons you may not be able to have the test or why the results may not be helpful include:

    Taking medicine, such aspirin, antacids, some antibiotics, corticosteroids, diuretics, barbiturates, sodium bicarbonate, or high doses of steroid hormones.
    Having a high body temperature (hyperthermia).
    Many medicines may change the results of this test. Be sure to tell your doctor about all the nonprescription and prescription medicines you take.
