WebLactic acid, also called lactate, is a product of pyruvate metabolism under anaerobic conditions. The tissues that produce most lactic acid are the muscle cells and red blood cells. An elevated lactate level and a pH equal to or less than 7.35 cause lactic acidosis. WebAs a consequence, the lactate concentration measured in whole blood (the method preferred for capillary samples) is only 60–70% of that measured in plasma after separation from the red cells; the latter method is often applied for venous blood. This must be taken into account for comparisons.
