Clinical Significance
Lactate (Lactic Acid) is primarily ordered to help determine if someone has lactic acidosis, a level of lactate that is high enough to disrupt a person's acid-base (ph) balance.
Lactic acid is a product of cell metabolism that can accumulate when cells lack sufficient oxygen and must turn to a less efficient means of energy production, or when a condition causes excess production or impaired clearance of lactate.
Lactic acidosis is most commonly caused by an inadequate amount of oxygen in cells and tissues (hypoxia). If someone has a condition that may lead to a decreased amount of oxygen delivered to cells and tissues, such as shock or congestive heart failure, this test can be used to help detect and evaluate the severity of hypoxia and lactic acidosis. It may be ordered along with blood gases to evaluate a person's acid/base balance and oxygenation.
Lactic Acid may also be used as part of an initial evaluation of someone who is suspected of having sepsis. Typically, if the person's lactate level is above normal limits, treatment will be initiated without delay. If a person with sepsis can be diagnosed and treated promptly, their chances of recovery are significantly improved.
Lactate levels may be ordered at intervals to help monitor hypoxia and response to treatment in a person being treated for an acute condition, such as sepsis, shock or heart attack, or a chronic condition, such as severe congestive heart failure.
