Look at your CMP (Comprehensive Metabolic Panel) blood test results. It has a test named Carbon Dioxide. This test may have a reference range of 20-32 mmol/L. Subtract your value from the max value -- that's your leftover buffer as the atmospheric CO2 rises, although serious intermittent problems are risked at a level of 31 itself. There is a more specific blood gas test that only a hospital can perform.

Fwiw, my value reliably went down after I replaced citrate mineral supplements (calcium and magnesium) with glycinate capsules.

Mine was 26 mmol/L yesterday, but the reference level is given as 22-29 by my lab, not 20-32.

		In an objective sense, I actually think your noted reference level is the more correct level. I say this because I have experienced problems in the 30-32 range. Granted, we know that each lab's reference range can also vary for other reasons.
