WebLactic acid is a chemical your body produces when your cells break down carbohydrates for energy. You might see it referred to as lactate. Muscle cells and red blood cells make the most lactic acid, but it can come from any tissue in your body. Most people think of lactic acid in their muscles during a tough workout. WebLactic acidosis is a medical condition characterized by a build-up of lactate (especially L-lactate) in the body, with formation of an excessively low pH in the bloodstream. It is a form of metabolic acidosis, in which excessive acid accumulates due to a problem with the body's oxidative metabolism.. Lactic acidosis is typically the result of an underlying acute or …

WebThe plasma lactate concentration was significantly higher ( P <0.001, approximately 50%) than in the erythrocytes. This difference was not altered by the venous blood lactate concentration or exercise intensity. A significant difference ( P <0.01) in lactate concentration was also found between capillary whole blood and venous whole blood. WebWhole blood lactate concentration was measured over 5 different times spanning 80-90 min in a blood gas lab at a major hospital center. Samples were stored at room temperature (22-24°C) or in slushed ice conditions (0.1-0.2°C) before analysis.
