Possibility of Venous Serum Cl Concentration ([Cl]) as a Marker for Human Metabolic Status: Correlation of [Cl] to Age, Fasting Blood Sugar (FBS), and Glycated Hemoglobin (HbA1c).

The HCO concentration in venous serum ([HCO]) is a factor commonly used for detecting the body pH and metabolic conditions. To exactly detect [HCO], the venous CO pressure should be kept as it is in the vein. The [HCO] measurement is technically complicated to apply for huge numbers of almost heathy persons taking only basic medical examinations.
