Lactate

What is lactate (lactic acid)?

Lactate, also known as lactic acid, is a chemical substance that naturally occurs in the body as a byproduct of anaerobic metabolism, the process in which energy is produced without oxygen. When your body requires more energy than it can supply through normal, oxygen-dependent processes, such as during intensive exertion, it produces lactate.

Why should you have lactate tested?

Testing lactate levels can be useful for assessing how well your body utilizes oxygen during exertion and for identifying the presence of certain medical conditions, such as lactic acidosis. It can also help in determining the appropriate training level for athletes.

What does it indicate?

Blood lactate levels can provide insight into the balance between oxygen demand and supply in the body. It assists in diagnosing lactic acidosis, a condition where lactate accumulates in the body and lowers the blood pH level, which can indicate issues such as oxygen deficiency in the body.

What does a high lactate level mean?

A high lactate level may indicate lactic acidosis, which can point to underlying issues such as heart failure, kidney failure, or severe infections. It can also result from physical overexertion, particularly in athletes.

What does a low lactate level mean?

A low lactate level is generally not concerning and may indicate that your body produces energy efficiently and handles the oxygen it utilizes well.
