laktátérték

Laktátérték refers to the concentration of lactate, a byproduct of anaerobic metabolism, in the blood. Lactate is produced when the body breaks down glucose for energy in the absence of sufficient oxygen. Under normal physiological conditions, lactate is produced at a low rate and is continuously cleared by the liver, heart, and other tissues. Therefore, a resting laktátérték is typically quite low.

Elevated laktátérték, also known as lactic acidosis when it reaches a significant level, can indicate an imbalance between lactate production and clearance. This imbalance can arise from various causes. In the context of physical activity, intense exercise can temporarily increase laktátérték as muscles work anaerobically. However, this is usually temporary and resolves with rest. Medical conditions that impair oxygen delivery to tissues, such as sepsis, shock, or severe anemia, can also lead to a sustained rise in laktátérték. Certain medications and metabolic disorders can also contribute to increased lactate levels.

Measuring laktátérték is a valuable diagnostic tool in clinical settings. It can help assess the severity of certain conditions, monitor treatment effectiveness, and guide therapeutic interventions. A persistently high laktátérték often signifies a serious underlying problem that requires prompt medical attention.
