LP14752-7   pH
pH is a measure of the acidity or basicity of a solution. It is defined as the cologarithm of dissolved hydrogen ions (H+). Hydrogen ion activity coefficients cannot be measured experimentally, so they are based on theoretical calculations. The pH scale is not an absolute one, it is relative to a set of internationally established standard solutions. pH 7.0 is considered neutral.

LP14752-7   pH
Potentia Hydrogenii, commonly known as pH, is a quantitative measurement of the acidity or basicity of a substance. A substance's pH value is based on a relative scale from 1-14 depending on the substance's proton ion concentration (H+). A higher proton ion concentration results in a lower pH value. Therefore, a pH value between 0 and 7 is an acidic substance whereas a pH value between 7 and 14 is an alkaline/basic substance. A pH value of exactly 7 is a neutral substance.

When the blood pH value is below normal range it is called acidosis. When the blood pH value is above normal range, it is called alkadosis. Acidosis/alkadosis can be divided into two categories: metabolic and respiratory. [https://labtestsonline.org/understanding/analytes/blood-gases/tab/test/] Source: Regenstrief LOINC

LP422982-1   BldCV
Central venous blood is blood found in the interior jugular or subclavian vein sampled via a central venous catheter. The composition of central venous blood is different from mixed venous blood, found in the pulmonary artery and also sampled via catheter, and peripheral venous blood, sampled via venipuncture. Central venous blood contains blood from the upper body, whereas mixed venous blood contains deoxygenated blood from the entire body. Source: LOINC
