WebbLactate is the end product of the metabolic process of glucose utilization, known as anaerobic glycolysis, which occurs in the cytosol of all cells. In well-oxygenated tissues this lactate is metabolized further, but if tissues are inadequately oxygenated, lactate accumulates locally and blood concentration rises. WebbThe occurrence of a transient increase in serum lactate level (hyperlactatemia) with or without lactic acidosis during short-term asthma treatment has been a well-known event for several decades.
