I have seen 7.2 - 11.7 fL ( http://www.ncbi.nlm.nih.gov/pubmed/21620440 ) 7.8-11 ( http://www.ncbi.nlm.nih.gov/pubmed/9666418 ) and 7.5-11.5 ( Mean platelet volume ). Or maybe there is no meaningful reference range at all ( http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3755496/ ). Richiez ( talk) 21:58, 30 April 2015 (UTC)
What agency in the U.S. determines the ranges for blood tests? and why do they change over time? — Preceding unsigned comment added by 71.219.204.185 ( talk) 19:15, 10 December 2015 (UTC)

The absolute carbon dioxide content listed in the acid-base and blood-gases table is correct, but deserves more explanation. Absolute carbon dioxide content includes dissolved CO2 as well as CO2 in the form of bicarbonate. The amount in the form of dissolved CO2 is only about 1.2 mEq/L, a small portion of the absolute carbon dioxide content, because CO2 is in equilibrium with bicarbonate in water and the equilibrium tends to favor the bicarbonate form over the dissolved CO2 form. Anatomy and Physiology texts explain that most carbon dioxide in blood is transported in the form of bicarbonate.
The huge (beautiful) graph in this article that shows references ranges for blood tests sorted by mass and molarity is particularly misleading in this regard since it shows CO2 being more abundant than bicarbonate. Most of the CO2 here is in fact in the form of bicarbonate, not actually CO2. It would be more informative for that graph to show "dissolved CO2" and have the concentration down around 1.2 mEq/L, becuase dissolved CO2 is in fact much less abundant in the blood than bicarbonate.
Here is a potential source/reference to use for this, though others should be found perhaps to confirm the 1.2 mEq/L (mmol/L) number. — Preceding unsigned comment added by NeilDD ( talk • contribs) 01:53, 4 May 2022 (UTC)
