This is not the same as the carbon dioxide gas you exhale; rather, it correspond the dissolved carbon dioxide that behave as a critical buffer to preserve the pH balance of your blood. When the lab reports a Co2 blood test low result, it point that your bicarbonate levels have drop below the standard reference orbit, which is typically between 23 and 29 millimoles per litre (mmol/L).
This precondition, technically known as metabolic acidosis, occurs when your body cumulate too much battery-acid or lose too much bicarbonate. Because your body work tirelessly to keep your blood pH within a very narrow, safe range (usually 7.35 to 7.45), even a slight dip in CO2 degree imprimatur attention from your healthcare supplier to identify the root cause.

Common Causes of Low Bicarbonate Levels
There is no individual reason for a Co2 blood test low determination.

- Kidney Disfunction: Since your kidneys are responsible for sustain bicarbonate levels, any impairment in kidney mapping can lead to lower CO2 in the roue.
- Diabetic Ketoacidosis (DKA): A serious complication of diabetes where the body create eminent levels of roue dot phone ketone, which speedily consume bicarbonate.
- Severe Diarrhea: Prolonged digestive issue can lead to a significant loss of bicarbonate through the dejection.
- Respiratory Alkalosis: Sometimes, hyperventilation (respire too fast) stimulate the body to exhale too much CO2, which can conduct to a compensatory dip in roue bicarbonate grade.
⚠️ Billet: If your rakehell test results testify very low CO2 along with symptoms like confusion, rapid respiration, or fruity-smelling breath, seek exigency aesculapian care immediately, as these can be signs of diabetic ketoacidosis.
Symptoms Associated with Low CO2
Ofttimes, a low CO2 solvent is institute apropos during a routine medical, mean you may have no symptoms at all.
