Normal value ranges may vary slightly among different laboratories. May also be used to differentiate between lactic acid acidosis and ketoacidosis by evaluating blood glucose levels. While the two terms are often used interchangeably, lactate is different from lactic acid. A level > 4 mmol/L defines lactic acidosis3, a level high enough to tip the acid-base balance, which may result in a serum pH < 7.35 in association with metabolic acidosis. Normal results range from 4.5 to 19.8 milligrams per deciliter (mg/dL) (0.5 to 2.2 millimoles per liter [mmol/L]). Lactate can be measured from both venous and arterial blood. Normal lactate levels range from 4.5 mg/dL to 19.8 mg/dL, MedlinePlus cites. Talk to your provider about the meaning of your specific test results. Technically speaking, an acid is a molecule which is capable of donating a hydrogen ion. Lactate measurements that evaluate the acid‐base status are used in the diagnosis and treatment of lactic acidosis (abnormally high acidity in the blood). I have also seen both used in the ICU to gauge a mortality outcome; with the Lactic Acid being more of a confirmation on an elevated Procal level. A: First, let’s spend some time talking about hyperlactatemia, defined as a persistent, mild to moderate (2-4 mmol/L) increase in blood lactate concentration without metabolic acidosis . A high lactate level in the blood means that the disease or condition a person has is causing lactate to accumulate. Talk to your provider about the meaning of … Severe levels of lactate are 4 mmol/L or higher. Normal Results. Furthermore, patients whose lactate level is less than or equal to 1.4 mmol/L may benefit from vasopressin infusion. Lactic acid tests are typically performed only in patients suspected of having lactic acidosis. Lactate is chemically similar to lactic acid, but does not possess the extra hydrogen[3]. Just my experience which as a New Grad (still feels weird to say that) is somewhat limited. 4. Normal lactate levels are less than two mmol/L, with hyperlactatemia defined as lactate levels between 2 mmol/L and 4 mmol/L. Normal value ranges may vary slightly among different laboratories. Normal results range from 4.5 to 19.8 milligrams per deciliter (mg/dL) (0.5 to 2.2 millimoles per liter [mmol/L]). Lactate is mainly metabolized in the liver . Lactate is produced by many cells of the human body, mostly by muscle cells. Patient Preparation There are no activity or medication restrictions unless by medical direction. 5. This test is most often done to diagnose lactic acidosis. Convert Lactate (Lactic Acid) level to mmol/L, µmol/L, mg/dL, mg/100mL, mg%, mg/L, µg/mL. In general, a greater increase in lactate means a greater severity of the condition. Do not exercise for several hours prior to taking the test because exercising can temporarily increase lactic acid levels. Lactate is different from lactic acid. Other definitions for lactic acidosis include pH less than or equal to 7.35 and lactatemia greater than 2 mmol/L with a partial pressure of carbon dioxide (PaC02) less than or equal to 42 mmHg. A normal blood lactate level is 0.5-1 mmol/L. Whereas lactic acidosis is characterized by persistently increased blood lactate levels (usually greater than 5 mmol/L) in association with metabolic acidosis. SI units Conversion Calculator. The normal value for lactic acid test is 4.5-19.8mg/dL, and this range is unisex for all age groups. Lactate concentrations within the "normal" range can be a useful prognostic indicator in septic shock. Levels around 4–5 mmol/l are universally accepted as being elevated. To assess for lactic acid acidosis related to poor organ perfusion and liver failure. Though, some old-school Attendings were mildly ambivalent about the results and still preferred Lactic Acid.
