Hyperlactatemia is defined as a persistent, mild to moderate (2-4 mmol/L) increase in blood lactate concentration without metabolic acidosis, whereas lactic acidosis is characterized by persistently increased blood lactate levels (usually >5 mmol/L) in association with metabolic acidosis.
A normal lactate level indicates that a person does not have lactic acidosis, that there is sufficient oxygen at the cellular level, and/or that their signs and symptoms are not caused by lactic acidosis. Is there anything else I should know? Increased lactate levels may be seen with thiamine (vitamin B1) deficiency.
